Hot enough to flow slowly 10 a large valley between two sets of opposite-facing Normal faults, resulting from tension forces in the rocks. 11 a river mouth where a river splits into many channels as it deposits sediment on meeting a lake or the sea 12 ground shaking caused by the energy that is released when rock on either side of a fault suddenly moves. 13 breakdown and removal of rock material by flowing water, wind, or moving ice. 14 slow breakdown of rock at the Earth's surface, due to climatic and biological processes. 15 rigid portions of the lithosphere that are constantly moving, exerting huge forces in the Earth's crust. volcanic ash plate tectonics delta rift valley weathering evaporation fossil abyssal plain expansion earthquake vent oxidation groundwater erosion mantle
