Erosion can be reduced by: predicting earthquakes stripping the land of trees planting crops at an angle breaking down large rocks

The correct answer is - planting crops at an angle;

The most effective way to stop the erosion is to cover the barren land with vegetation. By planting crops on the soil, the soil will be protected much more from erosion because the roots of the crops will hold it tight. Also the crops will be leaving a lot of organic material for decomposition which will contribute to the renewing of the soil's top layer. By planting the crops at an angle the efficiency will increase further more in the prevention of the erosion because the crops and their roots will be positioned in a manner that will not allow for exposure of the soil to the erosive processes, thus keep it in place.
