China 八年级（初二） Geography

Chapters: 12

1. Ch.1 China from a world view

Territory overview and administrative divisions (34 provincial units) · Population · Ethnic groups

Territory and Administrative Divisions: Where a Country Is and How It Is Divided – A country's location is described by its hemispheres and by what lies next to it: land neighbours and sea neighbours. To run a large country, the government splits it into smaller units such as provinces or states, and each unit into still smaller ones. China has 34 provincial-level units and India has 28 states and 8 union territories.
The World Population: Distribution, Density and Growth – People are not spread evenly on Earth. Most live on fertile plains near water; few live in deserts, high mountains or icy lands. Density tells how many people live on each square km. Geographical, economic and social factors explain the pattern. The world grew slowly for thousands of years and then very fast after 1800. Population changes through births, deaths and migration. The demographic transition theory shows how birth and death rates fall as a society moves from rural farming to urban industry. Countries use family planning and health care to control growth.
Ethnic Groups: Many Peoples, One Country – An ethnic group is a community that shares a history, language, customs or festivals. Most countries have more than one. Usually one group is much bigger and the others are smaller, and they often live mixed together, with some small groups gathered in particular regions. Respect and equality hold them together.

2. Ch.2 Natural environment

Landforms and terrain · Climate and its influences · Rivers and lakes (Yangtze, Yellow River) · Interdisciplinary: silt-flushing principle

Relief of a Country: Mountains, Plateaus, Plains and Delta – Relief means the ups and downs of the land. A country's relief is usually arranged in belts: high mountains, then hills and plateaus, then low plains, and at the end a river delta or the sea. The belts are linked by height, by rock type and by how they formed. Romania is a clear example: the Carpathian arc, the Transylvanian basin inside it, hills and plateaus around it, the Romanian Plain in the south and the Danube Delta by the Black Sea.
Climate Zones of the World – Climate is the average weather of a place over about 30 years. It depends mainly on latitude (how high the Sun climbs), altitude (about 6.5 °C cooler per km up), distance from the sea, winds and ocean currents. Using these, the Köppen system sorts the world into five groups: A tropical, B dry, C temperate, D continental and E polar, plus highland climates on high mountains. Monsoon climates have winds that change direction with the seasons.
Rivers: From Source to Sea – A river is fresh water flowing in a channel from high land (the source) to a sea, lake or bigger river (the mouth). On the way it erodes, transports and deposits rock. The upper course is steep, with V-shaped valleys and waterfalls. The middle course has meanders. The lower course is flat, with floodplains, levees and deltas. Heavy rain can make a river flood; we manage floods with hard (dams, levees) and soft (trees, floodplain zoning) methods. Lakes store water; rivers flow into and out of them.
Silt-Flushing Principle: Why Fast Water Carries Silt Away – Silt is tiny bits of soil in river water. Slow water drops it on the river bed. Fast water lifts it and carries it on. If the same water is squeezed into a narrower channel, it moves faster, so it can wash the bed clean.

3. Ch.3 Natural resources

Land resources · Water resources · Mineral resources · Marine resources · Interdisciplinary: world irrigation heritage

Land Use: How Communities Decide What Each Piece of Land Is For – Land use is what people do with land: homes, shops, factories, schools, roads, parks, farms and forest. The natural environment (rivers, slopes, soil, climate) sets the first limits. Then economic, social and cultural factors such as land price, jobs, transport and zoning rules shape the pattern, often in rings around the city centre. As towns grow they can sprawl outward or grow compactly upward. Changing land use changes ecosystems, so planning and conservation matter.
Water Resources and the Hydrosphere – Almost all of Earth's water is salty sea water. Only about 1% is liquid fresh water we can easily use, from groundwater, rivers and lakes. People often take water faster than nature refills it: aquifers fall, rivers run dry and wetlands shrink. Sustainable management means using no more than the recharge, sharing water fairly and keeping it clean. The ocean itself moves heat around the planet through thermohaline circulation, driven by differences in temperature and salt. Dirty water can be made safe by screening, settling, filtering and disinfecting. New sources include desalination, water reuse and rainwater harvesting, while saving water cuts demand.
Mineral and Energy Resources of India (Class 12) – Minerals are natural substances with a fixed make-up. Most of India's minerals lie in old plateau rocks, in three belts: the north-eastern plateau, the south-western plateau and the north-western belt. Metallic minerals include iron ore, manganese, bauxite and copper; mica is a non-metallic mineral. Coal, petroleum and natural gas are conventional energy that will run out. Nuclear, solar, wind, tidal, geothermal and bio-energy are non-conventional and cleaner. Because minerals are non-renewable, we must use less, recycle scrap and use substitutes.
Mineral Resources – A mineral is a natural solid formed in the earth, usually found mixed in rock. Useful minerals are mineral resources. The main groups are metals (iron, copper, aluminium), fuels (coal, oil, gas) and building or other minerals (sand, limestone, salt). We get them by open-pit or shaft mining, then crush and smelt ore to make metal. Minerals take millions of years to form, so we must use them wisely: reduce, reuse and recycle.
Oceans: The Sea Floor, Moving Water and Life – Oceans cover about 71% of the Earth. Their floor has a shallow continental shelf, a steep slope, a deep plain, underwater ridges and very deep trenches. Water moves in three ways: waves (made by wind), tides (made by the Moon's pull) and currents (rivers in the sea, warm and cold). Oceans give fish, salt, oil, gas and trade routes, and millions of people earn their living from them. Cyclones and tsunamis are ocean hazards; early warning saves lives. International rules (UNCLOS) set how far a country's sea rights reach: 12 nautical miles of territorial sea and a 200-mile Exclusive Economic Zone.
World Irrigation Heritage – Irrigation means bringing water to crops by canals, channels or tunnels. Some ancient systems still work after more than two thousand years. Dujiangyan splits a river with a fish-mouth island, takes a limited share through a narrow neck, sends flood water back over a spillway and throws sand outward with a bend, so no tall dam is needed. Other heritage systems include karez tunnels in dry lands, river weirs and village tanks in South Asia, and terrace water-sharing in Southeast Asia.

4. Ch.4 Economic development

Agriculture · Industry · Transport (highways, high-speed rail)

Agriculture Basics: How Farming Began, Changed and Feeds the World – Agriculture is growing crops and raising animals on purpose. It began about 10,000–12,000 years ago in several separate hearths, where people domesticated wild plants and animals; it then spread by diffusion. The Second Agricultural Revolution (about 1700–1900) brought better tools, crop rotation and machines, so fewer farmers fed more people. The Green Revolution (from the 1960s) used high-yield seeds, irrigation and fertiliser. Farming can be subsistence or commercial, intensive or extensive. The von Thünen model explains why land use forms rings around a market. Today agriculture is a global system facing challenges of sustainability, climate, land use, food security and fair roles for women.
Manufacturing Industries – Manufacturing changes raw materials into more valuable products. It gives jobs, reduces dependence on farming, and earns money through exports. Industries are grouped by raw material, role, capital, ownership and bulk. Their location depends on raw material, power, labour, capital, transport and market. Industries pollute air, water, land and cause noise, but this can be controlled.
Lifelines of National Economy – Transport, communication and trade connect producers with consumers and join the country together, like blood vessels in a body. India has roads, railways, pipelines, waterways, ports and airways. Communication carries messages; trade exchanges goods within and between countries. Tourism is also a trade that earns money and jobs.

5. Ch.5 Building a beautiful China

Natural hazards and disaster reduction · Environmental protection and development

Natural Hazards – A natural hazard is a natural event that can harm people and property, such as an earthquake, volcano, landslide, flood, drought or cyclone. It becomes a disaster when it hits people who are not ready. Geological hazards come from inside the Earth; meteorological (weather) hazards come from the air and water. Risk = hazard × vulnerability ÷ capacity to cope, so warning systems, strong buildings and trained people cut the damage.
Environmental Issues: Causes, Effects and Solutions – Environmental issues are harmful changes to air, water, land, climate and living things, mostly caused by human activity. The big ones are air pollution, water pollution, land pollution and waste, climate change, deforestation and loss of biodiversity, and overuse of resources. They grow with the number of people and how much each person uses (the ecological footprint). We can reduce them with clean energy, saving and recycling, treating waste water, protecting forests and good laws, at home, in the city, in the country and across the world.

6. Ch.6 Geographic differences

Four major regions; Qinling–Huaihe line · Interdisciplinary: 24 solar terms

Regional Geography: How We Divide the World into Regions – A region is an area that shares one or more features, which makes it different from the areas around it. Formal (uniform) regions are alike inside, like a plain or a rice-growing belt. Functional (nodal) regions are held together by links to a centre, like a city and the villages that travel to it. Perceptual regions exist in people's minds. Region edges are usually transition zones, and regions depend on each other through flows of people, goods, water and ideas.
The 24 Solar Terms – The 24 solar terms are a farming calendar made in ancient China. Farmers watched the sun and the noon shadow of a stick. They cut the year into 24 parts of about 15 days, each with a name that tells what the weather and the fields are doing. Four of them start the seasons, two are solstices and two are equinoxes. The calendar follows the sun, so the dates stay almost the same every year.

7. Ch.7 Northern region

Natural features and agriculture · Northeast provinces · Loess Plateau · Beijing, the capital

Natural Features and Agriculture – What a farmer can grow depends on four natural things: relief (land shape), temperature, water and soil. Cool, drier plains suit dry farming (wheat, maize); warm, wet lowlands suit paddy rice; dry lands allow farming only at oases and canals plus grassland herding; cold high plateaus allow hardy crops, terraces and yak or sheep herding.
Northeast China: Black Soil, Grain and Heavy Industry – Northeast China (Liaoning, Jilin and Heilongjiang) has long cold winters and warm short summers. Its flat plains have deep black soil, rich in humus, so it is a major grain base for corn, rice and soybean. Thick forests cover the Khingan and Changbai hills. Coal, iron and oil helped build heavy industry like steel, machines and cars. Today the region renews old factories and protects its black soil.
The Loess Plateau – The Loess Plateau in north China is covered by a very thick layer of loess: fine, yellow, wind-blown dust. The loose soil is carved by rain into gullies, leaving flat tablelands, long ridges and round hills. Heavy summer rain and few plants cause serious soil erosion, and the mud turns the Yellow River yellow. Planting grass and trees, building terraces and check dams, and farming gently have cut erosion and made the land greener.
Beijing, the Capital of China – Beijing is the capital of China. It lies on the northern edge of the North China Plain, with mountains to its north and west and the sea to its south-east. A capital has four jobs: government, culture, links with other countries, and new ideas and science. Beijing was planned along a straight central axis and holds many old buildings. As it grew, it added ring roads, metro lines and sub-centres to deal with crowding.

8. Ch.8 Southern region

Natural features and agriculture · Yangtze River Delta · Hong Kong and Macao SARs · Taiwan Province (physical geography, economy) · Interdisciplinary: origins of place names

Natural Features and Agriculture – What a farmer can grow depends on four natural things: relief (land shape), temperature, water and soil. Cool, drier plains suit dry farming (wheat, maize); warm, wet lowlands suit paddy rice; dry lands allow farming only at oases and canals plus grassland herding; cold high plateaus allow hardy crops, terraces and yak or sheep herding.
The Yangtze River Delta – The Yangtze River Delta is the flat land where China's longest river reaches the East China Sea. Silt carried by the river built the land. Canals cross it, with old water towns, rice and fish. Shanghai, a huge port and finance city, stands at the river mouth, and many other cities such as Suzhou, Nanjing, Hangzhou and Ningbo lie close by. Fast rail and roads link them into a city cluster, which is one of China's richest regions.
Hong Kong and Macao: the two Special Administrative Regions – Hong Kong and Macao are two small coastal places at the mouth of a big river on the south coast of China. Both are called Special Administrative Regions (SARs). Hong Kong is hilly, has a deep harbour and earns mostly from finance, trade and shipping. Macao is tiny and crowded, and earns mostly from tourism and hotels. Bridges, trains, water pipes and trade link both places to the mainland.
Taiwan: island landforms, climate, products and economy – Taiwan is a long island in the western Pacific, about 36,000 square km, off the south-east coast of the mainland across the Taiwan Strait (130 to 180 km wide). A mountain chain runs from north to south and Yushan (3,952 m) is the top peak. Plains are in the west, the east coast is steep. The Tropic of Cancer crosses it, so it is warm and wet, with typhoons. It grows rice, tea and fruit and is famous for electronics and computer chips. Trade and travel link it with the mainland.
Origins of place names: how names begin and how they change – Every place name is a small piece of history. Many names describe the land (hill, river, lake), some give a direction (north of the river), some honour people or events, and some tell what the place was famous for (a tea market). Names also change when rulers change, when a local language is brought back, when a new spelling system arrives or when towns join. To study a name, use maps, old records, language and the memory of elders.

9. Ch.9 Northwest region

Natural features and agriculture · Tarim Basin

Natural Features and Agriculture – What a farmer can grow depends on four natural things: relief (land shape), temperature, water and soil. Cool, drier plains suit dry farming (wheat, maize); warm, wet lowlands suit paddy rice; dry lands allow farming only at oases and canals plus grassland herding; cold high plateaus allow hardy crops, terraces and yak or sheep herding.
Tarim Basin: desert and oases, oil and gas, and ecological protection – The Tarim Basin is a huge inland bowl in north-west China, over 500,000 sq km, with the Tianshan, Kunlun and Pamir mountains around it. Its middle is the Taklamakan, a moving-sand desert with under 100 mm of rain a year. Snowmelt rivers from the mountains make green oases at the foothills where cotton and fruit grow. Under the sand are oil and gas, sent east by pipeline. Taking too much river water dries the lower Tarim River, so water saving, shelterbelts and careful sharing protect the land.

10. Ch.10 Qinghai–Tibet region

Natural features and agriculture · Sanjiangyuan (source of three rivers)

Natural Features and Agriculture – What a farmer can grow depends on four natural things: relief (land shape), temperature, water and soil. Cool, drier plains suit dry farming (wheat, maize); warm, wet lowlands suit paddy rice; dry lands allow farming only at oases and canals plus grassland herding; cold high plateaus allow hardy crops, terraces and yak or sheep herding.
Sanjiangyuan: the source region of the Yellow River, Yangtze and Lancang – Sanjiangyuan means "source of three rivers". It lies on the high Qinghai-Tibet Plateau, mostly above 4,000 m. Snow peaks, glaciers, lakes and wet meadows act like a sponge and give rise to the Yellow River, the Yangtze and the Lancang (called Mekong downstream). About half of the Yellow River water and a quarter of the Yangtze water start here, so it is called a "water tower". Too many grazing animals and a warming climate shrink grass and wetlands, so a national park and careful grazing now protect it.

11. Ch.11 China making progress

Regional development overview

Regional Development – Regional development means improving the economy and living standards of different places in a country. Investment, jobs and people tend to gather in a few big hubs, while smaller towns lose young people and services. This causes crowding, high rent and conflict in hubs and decline elsewhere. Policies like new growth centres, better roads and local jobs aim for balanced development.

12. Geographic tools and fieldwork

Globe and maps (latitude, longitude, contour maps, digital maps, satellite navigation) · Experiments, surveys, fieldwork · Home region study

Map Skills: Reading and Using Maps – A map is a flat, scaled-down view of a place from directly above. To read one you need: the key (symbols), the scale (to measure distance), direction (compass points and bearings), grid references (to find and give a location) and contour lines (to see height and slope). Today GPS finds our position from satellites, and GIS stacks many map layers of data on a computer to answer questions about places.
Geographical Enquiry and Fieldwork – A geographical enquiry is a small research project about a real place. It follows clear steps: ask a question and write a hypothesis; collect primary data (your own measurements and surveys) and secondary data (census, maps, websites) using a fair sampling method; process and present the data in suitable graphs and maps; analyse the pattern and reach a conclusion; then evaluate how reliable the results are. The same skills are used to make decisions: weigh options using evidence and justify the best one. Older students write a longer independent investigation with their own question, primary and secondary data, analysis and conclusions.
Local Geography: Studying Your Own Region – Local geography is the study of the place where you live: your town, district or home region. A full description answers six questions: where it is (position), what nature gives it (relief, climate, water, soil, forests, minerals, protected areas), who lives there and how (population and settlements), how people earn a living (economy, jobs and services), what the environment is like and how it is monitored, and how all of this has changed over time. Geographers find the answers with a field study: ask a question, collect data by observing, measuring and interviewing, show it on sketch maps and graphs, and draw conclusions about strengths, problems and ideas for the future.
