What are plains and how are they formed?

Plains are flat and large stretches of land formed by river deposits, erosion, or tectonic movements. Plains are one of the major landforms on Earth. They can be formed in different ways, such as the deposition of sediments by rivers, the erosion of high lands, or the uplifting of land during tectonic activities.

Types of Plains

• Alluvial Plains: Formed by rivers depositing sand and silt over time (e.g., Indo-Gangetic Plain).
• Structural Plains: Formed due to uplift or subsidence of land.
• Erosional Plains: Formed by erosion of high lands over millions of years.

Plains are important for agriculture due to their fertile soil and flat terrain which makes farming easier.
