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

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.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
