Geography is the study of the Earth and its features, both natural and human-made. It can be divided into two main branches: physical geography, which examines the natural environment including landforms, climate, plants and animals; and human geography, which focuses on how human societies interact with and change the environment through activities like agriculture, industry and urbanization. Geography is an important field of study as it helps explain the relationships between humans and their surroundings at various scales, from local to global. Understanding geography promotes awareness of world issues and makes people better global citizens.
