The study of landforms and their evolution is called:

Correct option is C

The correct answer is (C) Geomorphology.

Geomorphology is the scientific study of landforms and the processes that shape them. It involves understanding the formation, evolution, and classification of various landforms like mountains, rivers, valleys, and deserts. Geomorphologists study the forces of nature (such as weathering, erosion, and tectonic activity) that contribute to the development and transformation of the Earth's surface over time.

• Soil Geography: This refers to the study of the distribution, formation, and characteristics of soils across the Earth's surface. It's a branch of geography concerned with the relationship between soil and the environment.

• Climatology: This is the study of climate, which involves examining long-term weather patterns, variations, and their effects on the environment. It's focused on atmospheric conditions rather than landforms.

•  Hydrology: This is the study of water, particularly the distribution, movement, and properties of water in the Earth's atmosphere and on its surface. Hydrologists study rivers, lakes, groundwater, and precipitation but not the landforms themselves.
