Question

Which of the following is a method used to prevent soil erosion? A. Tilling the soil / B. Contour farming / C. Adding worms to soil / D. Adding fertilizers to soil

Answer 1

Answer: B. Contour farming

Explanation:

Contour farming is a sustainable practice of conserving the soil from erosion so as to retain it's fertility for the next harvest.  In this method plants are grown over the contours of the slopes at a slight elevation. This process allows the absorption of water by the soil and prevents the surface runoff. Hence, prevents the loss of soil fertility by soil erosion due to water.

Answer 2

I'd say
B. Contour Farming 
since it's planting on a flat surface and creating w/ridges to help prevent water from taking the crops away
