Russia 10 класс Geography (basic)

1. Geography as a science

Methods of geography

• 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. Nature use and geoecology

Geographic environment · Natural resources

• Resources and Development – A resource is anything in nature that people can use with the help of technology. Resources can be grouped by origin, by how long they last, by who owns them and by how much we have developed them. India must plan how it uses resources, look after its land, and protect its soils from erosion.

4. World population

Population dynamics · Composition and distribution

• 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.
• 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.

5. World economy

Structure of the world economy · Branches of world economy

• Globalisation and Global Governance – Globalisation is the growth of flows of goods, capital, information and labour that tie places together. Technology, transport and trade deals drive it. The flows are unequal: rich economies hold more power, poorer ones have weaker market access. TNCs spread production of one product across many places. Agencies like the UN, WTO, IMF and World Bank try to govern these flows, and treaties protect global commons such as Antarctica. Globalisation brings growth and cheaper goods but also inequality, conflict and environmental harm.
