1. Weathering and Erosion | 风化与侵蚀
Freeze-thaw weathering: Water enters cracks in rocks, freezes and expands by 9%, exerting pressure that widens the cracks. Repeated cycles break the rock apart. Most effective where temperatures oscillate around 0 °C.
冻融风化： 水渗入岩石裂缝，冻结时体积膨胀约9%，产生压力使裂缝扩大。反复冻融使岩石破碎。在温度常在0°C上下波动的地区最为显著。速记：冰撑裂岩石，像冰箱中结冰撑裂瓶子。
Biological weathering: Roots of plants grow into cracks and fissures, prying rocks apart. Burrowing animals and lichen acids also contribute to the mechanical and chemical breakdown of rocks.
