World Geography
World Geography is the study of the Earth's physical features and how they relate to the environment and humans. It covers everything from high mountains to deep ocean basins. For competitive exams like UPSC, this subject is divided into physical geography and economic geography. Physical geography looks at landforms like Fold and Block mountains. Fold mountains, such as the Andes in South America or the Himalayas in Asia, are formed when the Earth's crust is pushed together.

These are carbon-rich wetlands found in tropical regions. The Congo Basin holds a massive amount of peat. They are 'carbon sinks,' meaning they trap carbon dioxide.
These are carbon-rich wetlands found in tropical regions. The Congo Basin holds a massive amount of peat. They are 'carbon sinks,' meaning they trap carbon dioxide. If they are drained or burned, they release three years' worth of global fossil fuel emissions.
On June 21, the Sun is directly over the Tropic of Cancer. This results in the longest day of the year for the Northern Hemisphere. Any place from the Equator to the North Pole will see more than 12 hours of sunlight on this day.

Mountains are classified by how they are formed. Fold mountains (like the Alps and Andes) are created by pushing forces. Block mountains (like the Vosges) are created by cracking or faulting forces.
