Geomorphology is the study of the Earth’s surface features and their processes of formation. It is a branch of geology that deals with the physical and chemical processes that shape the Earth’s surface, including weathering, erosion, and deposition.
Hydrology is the study of water on, above, and below the Earth’s surface. It is a branch of Earth science that deals with the distribution, movement, and properties of water.
Biogeography is the study of the distribution of plants and animals on Earth. It is a branch of biology that deals with the geographic distribution of species and the factors that influence it.
Pedology is the study of soils, while geomorphology, hydrology, and biogeography are the study of the Earth’s surface, water, and plants and animals, respectively.
