Geography (from Greek: γεωγραφία, geographia, literally "earth description") is the study of earth and its people. Its features are things like continents, seas, rivers and mountains. Its inhabitants are all the people and animals that live on it. Its phenomena are the things that happen like tides, winds, and earthquakes.
A person who is an expert in geography is a geographer. A geographer tries to understand the world and the things that are in it, how they started and how they have changed.
Geography is divided into two main parts called physical geography and human geography. Physical geography studies the natural environment and human geography studies the human environment. The human environmental studies would include things such as the population in a country, how a country's economy is doing, and more. There is also environmental geography.
