Question

explain how deforestation is responsible for land degradation and soil erosion

Answer 1

deforestation is responsible for land degradation because due to deforestation since the roots hold the soil firmly and when we cut trees the soil gets loose and this can be eroded easily by the natural actions such as rain wind etc. so we can conclude that trees prevent soil erosion and thus Land Degradation

Answer 2

as we know that roots of trees holds the soil around it. Therefore if this trees are cutted then there will be nothing to hold the soil and thus the soil can easily be eroded by the wind or water.
