Question

Soil erosion is prevented by …………………. of grasses.

• A. fibrous roots of grasses
• B. Tap roots
• C. All of above
• D. Bushes

Answer 1

The correct option is A fibrous roots of grasses

Plants of the grass family have a fibrous root system and not a tap root system. Fibrous roots spread through the soil and help to hold the soil more firmly than tap roots. This helps prevent washing away of soil and thus, helps in conserving soil.
