Explain the difference between an alluvial plain and an eroded plain, and give one example of each from India.
Answer
An alluvial plain is formed by deposition of river sediments, e.g., the Gangetic plain; an eroded plain results from weathering and erosion of rocks, e.g., the Deccan Plateau.
Step-by-step solution
- Step 1: Define an alluvial plain as land formed by the deposition of sediments by flowing rivers.
- Step 2: Give an Indian example – the Gangetic plain.
- Step 3: Define an eroded plain as land that has been worn away by weathering and erosion.
- Step 4: Give an Indian example – the Deccan Plateau.
Common mistake: Mixing deposition and erosion terms
Concept tested: Types of plains and their formation
