Answer 1

Answer: (A), (B), (C)

The correct options are
A

reduces soil erosion

B

reduces air pollution

C

reduces noise pollution

Roots of trees bind the soil and can reduce the chance of flood and soil erosion. Carbon dioxide is one of the major gases that affects the atmosphere. Plants balance the percentages of carbon dioxide and oxygen in the atmosphere. Trees can act as sound barries between the source of sound and the hearer thereby decreasing the intensity of sound and reducing noise pollution.
