Question

Where is contour ploughing done ?

• A. Plain area
• B. Coastal area
• C. Mountainous area
• D. All of these

Hint:

Associate "contour" with the lines on a topographical map that show elevation. Therefore, contour ploughing is a technique used on sloped land (hills and mountains) to combat soil erosion by water.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Contour ploughing is a specific farming technique designed to conserve soil and water. The question asks where this technique is typically practiced.

Step 2: Detailed Explanation:
Contour ploughing is the practice of ploughing and planting crops along lines of equal elevation, following the contours of a slope. This is done in hilly or mountainous areas. The furrows and ridges created by this method act as small dams, slowing down the flow of rainwater down the slope. This prevents the formation of gullies, reduces soil erosion, and allows more water to infiltrate the soil. This technique is not needed in plain or flat coastal areas where water runoff and slope-related erosion are not major issues.

Step 3: Final Answer:
Contour ploughing is done in mountainous areas.
