Question
Fully saturated soils have a steeper angle of repose than drier soils. True O False DQuestion 21 Because low-latitude areas receive far more solar radiation than polar areas, high-altitude tropical mountains experience very little freeze-thaw weathering True False Question 22 Which of the following statements about weathering is TRUE? O Physical weathering precedes chemical weathering Physical weathering exposes more surface area, so that chemical weathering takes place faster O Chemical weathering precedes physical weathering Mass movement takes place before either physical or chemical weathering.Explanation / Answer
20) false
it will be higher for slightly wet soil because the surface tension between water and soil grains bound them together, but when it saturated with water angle of repose reduces and the grains will flow like a fluid.
21) False
freeze thaw weathering occurs when the ice freezes in the rock gap and due to the expansion of its volume rocks will crack and it will lead to the breaking of rocks, melting of ice and freezing will be higher in the low latitude region mountains.
22) physical weathering exposes more surface area, so that chemical weathering takes place faster.
