उत्तर
Structural Plain:
- Formation: A structural plain is formed due to the uplift or subsidence of land caused by tectonic forces.
- Characteristics: These plains are typically flat, large areas of land formed by geological processes like faulting and folding. They are often found in regions where the land has been uplifted or subsided, such as plateau regions or basins.
- Example: The Great Plains of the USA.
Depositional Plain:
- Formation: A depositional plain is formed by the accumulation of sediments deposited by natural agents like rivers, glaciers, and wind.
- Characteristics: These plains are formed by sedimentation and are typically fertile, flat areas of land. They often occur in areas near rivers, lakes, or coastlines where material has been deposited over time.
- Example: The Indo-Gangetic Plains in India.
