Rock cycle, snap! Rock cycle, snap! – First game cementation the process which ‘glues’ sediments to form rocks sedimentary rocks rocks formed in layers at the surface of the Earth, either in water or on land fossils the remains or imprints of plants and animals found in rocks igneous rock a rock formed from melted rock which has cooled and solidified metamorphic rock a rock changed by intense heat and/or pressure erosion the wearing away of rocks by the sea, glaciers or rivers etc. minerals the grains of a single substance found in rocks melting the process of changing from a solid rock to a liquid rock lithification the process where sediments compact under pressure and gradually become solid rock weathering the process of breaking up and weakening the surface of rocks in situ Rock cycle, snap! – Second game transportation the process which moves pieces of rock slate, marble and gneiss examples of metamorphic rocks the wearing away of rocks by the sea, glaciers or rivers etc. the process of breaking up and weakening the surface of rocks in situ erosion weathering basalt a type of lava marble metamorphosed limestone the mixture of molten or semi molten rock found inside the Earth a type of granular and crystalline intrusive igneous rock the process of changing from a solid rock to a liquid rock magma granite melting chalk, sandstone and limestone © www.teachitgeography.co.uk 2012 examples of sedimentary rocks 18849 Page 1 of 1
