Chapters: 7
1. National land and geographic information
Korea's location in the world · Traditional views of land in old maps · Collecting and analysing geo-information
- 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.
- Old Maps and Worldviews: How People Saw the Land – An old map is not a mistake-filled modern map. It is a picture of what its makers knew and believed. Early maps began as local sketches. Round maps placed the maker’s own region at the centre and often put east or south at the top. Grid ideas (latitude and longitude) let places be measured. Many cultures also read land through belief, such as feng shui: hill behind, water in front. Reading old maps means asking who made them, why, and how they saw the world.
- Spatial Information Technology: GIS (Class 12 Geography Practical) – A Geographical Information System (GIS) is a computer system that stores, links, analyses and shows data about places. It keeps the world in layers. It needs hardware, software, data, people and methods. Spatial data come in raster (grid of cells) and vector (points, lines, polygons) formats. Data are entered by digitising, scanning, GPS or satellite images and linked to attribute tables. Overlay combines layers to find where conditions meet; buffer draws a zone of fixed distance around a feature.
2. Landforms and human life
Formation of the peninsula and mountains · River and coastal landforms · Volcanic and karst landforms
- Major Landforms and How They Form – Landforms are the natural shapes of the land: mountains, volcanoes, plains, valleys, deltas, beaches and caves. Forces from inside the Earth (plate movement, volcanoes) build them up. Forces from outside (rain, rivers, waves, wind, ice) wear them down and move the pieces. People choose where to live and work according to these landforms.
3. Climate and human life
Korea's climate · Climate landscapes · Natural hazards and climate change
- 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.
- Cultural Geography: How Places Shape Culture and Culture Shapes Places – Cultural geography studies how human culture differs from place to place and how it spreads. Culture is a group's shared way of life: language, religion, food, clothing, buildings, art and festivals. People change the land to fit their culture, making a cultural landscape. The natural environment, especially climate and nearness to the sea, influences homes, food and clothing, though people also use technology and choice. Areas with similar traits form culture regions. Cultures start in hearths and spread by diffusion: relocation (people move) or expansion (the idea moves), which can be contagious, hierarchical or stimulus. Diffusion can lead to acculturation, assimilation, syncretism and, today, globalisation.
- 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.
4. Settlements and regional development
Rural change · Urban structure · Urban planning · Effects of regional development
- Rural Geography: How Countryside Areas Live and Change – Rural areas have few people per square kilometre, lots of open land and small settlements. Farming shaped them, but machines mean fewer farm jobs. Today rural land has many uses: homes for commuters, tourism, nature protection and energy. Areas near cities often grow (the rural-urban fringe), while remote areas may lose people and services. Farmers, residents, local councils and businesses all want different things, so land-use planning sets rules.
- Urbanisation: Why Cities Grow and How to Make Them Work – Urbanisation is the rise in the share of a country's or the world's people who live in towns and cities. In 1950 about 30% of the world was urban; since 2007 more than half is, and about 68% is expected by 2050. Cities grow by rural–urban migration (push factors from the countryside, pull factors to the city) and by natural increase. Today the fastest growth is in lower-income and newly emerging countries of Asia and Africa, where megacities of 10 million or more are forming; in many rich countries growth is slow and people also move out to suburbs (suburbanisation and counter-urbanisation). Fast growth brings opportunities (jobs, services) and problems (informal housing, traffic, pollution, waste, flooding, the urban heat island). Sustainable urban development tries to fix these with public transport, green spaces, clean water, recycling, affordable housing and renewable energy.
- Urban Planning and the Quality of Urban Life – Urban planning means deciding in advance how land in a town or city will be used, where roads, homes, jobs, parks and services go, and how the place will grow. Without planning, cities sprawl over farmland, traffic jams grow and slums lack water and drains. Planners use land-use zoning, public transport, the right density and green space to raise the quality of life. They measure it with factors such as housing, jobs, clean air, services, transport and safety. Modern ideas include the liveable city, the 15-minute neighbourhood, smart cities and city branding. Villages and small towns are planned too, as a shared social task.
- 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.
5. Production and consumption
Resources · Agriculture · Industry · Commerce and services
- Natural Resources – Natural resources are useful things we take from nature: sunlight, wind, water, soil, forests, minerals, oil, gas and coal. Renewable resources come back in a human lifetime; non-renewable ones took millions of years to form and run out when used. Resources are spread unevenly because they form only where certain geological processes happened in the past (old seas, volcanoes, mountain building). Using them brings benefits such as energy, jobs and materials, but also costs such as pollution, habitat loss and hazards, so societies weigh costs against benefits and try to use them sustainably.
- 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.
- Economic Geography: Where Things Are Made and How They Move – Economic geography studies where people produce, trade and consume, and why. Work is grouped into sectors: primary (farming, fishing, mining), secondary (factories, building) and tertiary (shops, transport, banks, software, tourism); a quaternary sector of research and information is sometimes added. Firms choose places that cut costs and reach buyers: raw materials, energy, transport, workers, markets, government support and nature all matter. Most products are now made in global value chains, with steps spread over many places; value grows most at design, branding and sale. Multinational firms and public actors (states, regions, cities) shape these spaces. Goods move in containers and trucks, while money, data and ideas flow through cables. Production crowds into big cities (metropolises) and coasts, and places compete to attract firms. Old industrial regions restructure, sometimes shrinking and sometimes turning to new industries and services.
6. Population and multicultural space
Population distribution · Low birth rate and ageing · Migrants and multicultural families
- 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.
- Population Ageing – Population ageing means older people form a growing share of a population. It has two drivers: fewer births (total fertility rate below about 2.1) and longer lives. Fewer workers per older person strains pensions, health care and the labour supply, while schools need fewer places. Societies respond with support for families, later and flexible retirement, pension and care reforms, technology, lifelong learning and sometimes immigration.
- Migration – Migration is the movement of people from one place to another to live there, for some time or for good. The place left is the origin; the place reached is the destination. People move because of push factors (problems at home) and pull factors (attractions elsewhere), but obstacles like cost, distance and laws stop some. Migration can be internal or international, temporary or permanent, voluntary or forced, and it changes both the origin and the destination.

- 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.
