Ploughing along the contours of a slope to slow down running water is called:
AStrip cropping along the slope
BTerrace farming on the slope
CContour ploughing across the slope
DShelter belts against erosion
Answer & Solution
Correct answer: C. Contour ploughing across the slope
Contour ploughing is ploughing ALONG the contour lines of a slope (across, not up-and-down). It slows water, prevents gullies, and conserves soil. Terrace farming cuts steps; strip cropping alternates strips; shelter belts break wind.
