Answer to Question 1
Climate influences the rate and type of weathering, which in turn will affect the type of mass movements. Some lines of evidence to support this statement are:
In arid regions, the weathering zone is shallow, and mudflows are likely to result.
In humid regions, the weathering zone is deeper and resultant mass movements like earth flows and creep.
Physical and chemical weathering can enlarge and weaken joints and fractures resulting in rock falls and slides.
