- Distribution of Oceans and Continents: Drift, Spreading and Plates – In 1912 Alfred Wegener said all continents were once one landmass, Pangaea, surrounded by one ocean, Panthalassa, and that they drifted apart. Matching coastlines, rocks, fossils, glacier deposits and placer gold supported him, but he could not explain the force. Mapping the ocean floor showed ridges, plains and trenches; Harry Hess then proposed sea-floor spreading: new crust forms at mid-ocean ridges and old crust sinks at trenches. This led to plate tectonics: the lithosphere is broken into rigid plates that move on the soft asthenosphere and meet at divergent, convergent and transform boundaries. The Indian plate broke away from the south, moved north, and collided with Asia to raise the Himalayas.
- 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.
- 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.

- The Making of a Global World – People, goods, ideas and germs have moved across the world for thousands of years: on the silk routes, with food crops like potato and maize, and with diseases like smallpox. Between 1815 and 1914 the world economy grew through three flows: goods, labour and capital, helped by railways, steamships and refrigerated ships. Colonies paid a price: rinderpest in Africa and indentured labour from India. After the First World War came mass production in the USA and then the Great Depression of 1929, which hit India's farmers hard. After 1945, the Bretton Woods system, the IMF and the World Bank rebuilt the world economy.
- Development Geography: Why Places Are Rich or Poor – Development means people living better lives: more income, better health, more schooling and more freedom. We measure it with indicators such as GNI per person, life expectancy and years at school, and with the Human Development Index (HDI, 0 to 1), which joins all three. Development is uneven: rich cores and poorer peripheries exist between world regions and inside one country. Where rich and poor areas touch, there are strong contrasts and flows of workers, goods, factories and money, with both good and bad effects. There is no single model of development: countries have grown through export factories, services, or mines and farming, each with risks.
- 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.
