Granite (heat)) o Sedimentary- rocks formed through the layering of mineral particles (ex. Limestone (deposition)) o Metamorphic- existing rocks are altered through heat/pressure (ex. Shale transformed into slate (heat/pressure)) Landform Processes  Erosional processes: the wearing away of something by a force o Water, ice, wind  Depositional processes: o Water, ice, wind
