Geography is the study of the Earth and its features. It aims to spatially and holistically synthesize how physical landscapes, environments, and human activities are interconnected. Geography can be approached systematically, by examining specific phenomena globally, or regionally, by focusing on individual areas. Key branches of physical geography include geomorphology, climatology, hydrology, and soil geography. These natural sciences inform the study of landforms, atmosphere, hydrosphere, and biosphere. Human geography also encompasses social, cultural, population, economic, historical, and political studies. Physical geography is important as it influences settlement patterns, industries, agriculture, and more.
