Answer 1

Answer: (A), (B), (D)

Shelterbelts

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Soil erosion on hill slopes can be checked by contour barriers and by making flat terraces. Ploughing done along contour barriers is called Contour Ploughing. In dry areas, to reduce the force of the wind, trees are planted to protect soil cover and form a shelterbelt. Overgrazing is a human activity which results in soil erosion.
