igneous rock - rocks that have formed by the cooling and hardening of molten lava or magma., sedimentary rock - made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock., metamorphic rock - formed when other rocks are affected by great temperatures and pressures. They do not melt, but the chemicals they contain may change their forms, or crystal shapes. Marble and slate are two examples., magma - molten rock within (inside) the earth, lava - hot, liquefied rock that flows from a volcano or other opening in the surface of Earth., erosion - The process by which soil and rock is removed from one area of the Earth through natural causes such as wind, water, and ice and transported elsewhere is called ..., weathering - describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all causes of ..., compaction - the weight of layers of sediment upon layers of sediment causes pressure that makes the layers more compact., cementation - Dissolved minerals become deposited in the spaces between sediments. These minerals act like glue to cement the sediments together., pressure - the force over a given area, sediment - material (as stones and sand) carried onto land or into water by water, wind, or a glacier,
