What are three ways that climate affects the rate of weathering?

Climate is a major factor in the weathering of rocks. Some aspects of climate such as average temperature, rainfall, and the presence or lack of trees and plant life can also impact weathering. Temperature can impact weathering because the freezing and thawing can lead to weathering of rocks. Rainfall has an impact on weathering because some rocks weather more easily in wet climates and others weather more easily in dry climates. In addition the presence of plant life can lead to the weathering of rocks because tree roots and other plant features can help to break up or weather rocks.
