What factors contribute to mass wasting in tropical versus arid and semiarid climates? What will be an ideal response?
In the tropics, high temperatures and rainfall extend weathering to depths of tens of meters, and mass
movements are common in the deep weathering zone. In arid and semiarid regions, the weathering
zone is much shallower, but a short period of intense rain falling on a slope with little vegetation to
absorb the water can cause rapid runoff and mass wasting.
