Hot enough to flow slowly 4 a growth in volume which happens when most solids get hotter, but also when water freezes to form ice. 5 deep ocean floor, generally flat apart from occasional volcanic mountains and mid-ocean ridges 6 breakdown and removal of rock material by flowing water, wind, or moving ice. 7 ground shaking caused by the energy that is released when rock on either side of a fault suddenly moves. 8 a river mouth where a river splits into many channels as it deposits sediment on meeting a lake or the sea 9 drying out of sea water, usually, in warm, dry climates, leaving behind deposits of crystallized mineral salts 10 rigid portions of the lithosphere that are constantly moving, exerting huge forces in the Earth's crust. 11 fragments of rock and pumice thrown out of volcanoes by explosive eruptions, The finest particles are carried long distances by winds. 12 slow breakdown of rock at the Earth's surface, due to climatic and biological processes. 13 a large valley between two sets of opposite-facing Normal faults, resulting from tension forces in the rocks. 14 a weathering process where iron-rich minerals (usually) react with air to form rusty-brown oxides. 15 water trapped in gaps between the grains of rocks (usually sedimentary rocks) beneath the surface. plate tectonics expansion delta vent groundwater mantle earthquake erosion evaporation weathering oxidation fossil volcanic ash rift valley abyssal plain
