Question

Which of the following is a method used to prevent soil erosion?
Answer

Tilling the soil

Contour farming

Adding worms to soil

Adding fertilizers to soil

Answer 1

Contour Farming

Answer 2

Not tilling the soil, because it actually only breaks it apart.

Not adding worms, because they create holes in the earth, they do not bind them.

Adding fertilizers only help nutrition, not the physical properties of soil.

Thus, B is the answer.

Why? This is why:

Contour plowing (or contour ploughing) or contour farming is the farming practice of plowing across a slope following its elevation contour lines. The rows formed slow water run-off during rainstorms to prevent soil erosion and allow the water time to settle into the soil. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level. A similar practice is contour bunding where stones are placed around the contours of slopes.
