The term lithosphere is derived from the Greek words … WebThe lithosphere refers to the solid outer layer of the Earth, which includes rocks and soil. Drought can affect this layer in several ways, one of which is increased erosion and weathering. Erosion is the process by which rock and soil are worn away by wind or water. During a drought, there is less vegetation to hold soil in place, making it ...
