The picture shows an example of contour plowing. how does this method farmers? a. it reduces soil erosion. b. it reduces landslides. c. it reduces flooding. d. it increases crop yield. e. it reduces pollution.

Answer is: A. It reduces soil erosion.

Contour plowing or contour farming is the plowing and planting across a slope following its elevation contour lines.

This lines create a water break which reduces the formation of rills during rains, because lines let more time for the water to settle (stay) into the soil.

Contour plowing is effective on slopes with between 2% and 10% gradient.

The correct answer is option A which is It reduces soil erosion.
