IMPORTANT QUESTION AND ANSWER

Answer The Following Questions:

1. How much rainfall occurs annually on the Earth’s surface?

Ans: The Earth’s surface receives about 108 × 10¹⁷ litres (around 1,08,000 cubic kilometres) of rainfall every year.

2. How much sediment does the Brahmaputra River carry annually toward the plains?

Ans: The Brahmaputra River carries about 616 crore tons of sediment annually toward the plains.

3. What is a Plunge Pool?

Ans: At the base of a waterfall, water falls with great force and forms a large, deep depression called a plunge pool.

4. What is meant by an Alluvial Fan?

Ans: When a river descends from a mountain to a plain with a steep slope, the sediments spread out in a fan shape, forming an alluvial fan.

5. What is the area of the world’s largest delta — the Sundarbans?

Long Question & Answer:

1. What is the Fluvial Process? How does it form landforms?

Ans: The fluvial process refers to erosion, transportation, and deposition carried out by rivers and surface water.

Rivers erode rocks and soil from highlands and carry sediments downstream.These materials are later deposited in plains, deltas, and river basins.Erosion forms valleys and gorges; transportation moves sediments; deposition creates flood plains and deltas.Thus, running water continuously shapes and modifies the Earth’s landforms.

2. What are Flood Plains and Deltas? Explain their formation.

Ans: Flood plains are flat areas on both sides of a river that flood during heavy rainfall.

Sediments deposited by floodwater make the land fertile and ideal for agriculture. Deltas form when a river slows down near the sea and deposits sediments at its mouth. The Ganga-Brahmaputra Delta is the world’s largest, spread across India and Bangladesh.
