Geography

Earth's lithosphere is broken into moving plates whose interactions build mountains, cause quakes, and shape continents.

Earthquakes and volcanoes occur mainly at plate boundaries and result from the release of built-up stress in the Earth's crust.

Water continuously moves between the atmosphere, land, and oceans through evaporation, condensation, and precipitation.

Weather describes short-term atmospheric conditions, while climate describes long-term average patterns over decades.

Rivers shape landscapes through erosion, transportation, and deposition as they flow from source to mouth.

Climate change refers to long-term shifts in temperature and weather patterns, largely driven by human greenhouse gas emissions.

Ecosystems are communities of living organisms interacting with their environment, and biomes are large regions with distinct climate and life.

Natural resources sustain human life and economies, but their extraction and use must be managed sustainably to avoid depletion and environmental harm.

Human populations grow, shrink, and move due to economic, social, political, and environmental factors.

Urbanisation is the growing shift of population from rural to urban areas, reshaping cities and economies worldwide.
