Question

A region experiences frequent landslides from heavy rains. How can the local residents lower the frequency of landslides in the region?
Start contour plowing on the slopes where landslides happen.

Plant vegetation on the slopes that experience landsides.

Encourage deforestation in the regions that haven’t suffered landslides.

Divert water so it flows into the affected region.

Reduce the slopes where landslides occur.

Answer 1

Answer:

The correct answers are the statements 1st and 2nd.

Explanation:

A landslide refers to the movement of debris, rocks, or the earth down the slope. It refers to the down-slope rock and soil movement under the effect of gravity that causes enormous destruction to property and life on Earth.  

In order to restrict the occurrences of landslides, the native residents should try to minimize the loss of soil in order to limit the erosion of soil. Therefore, the best approach in the given case would be to do contour plowing and planting vegetation on the slope, as it helps in holding the soil.
