Sedimentary Igneous Metamorphic Rock Sedimentary Rock What is

Sedimentary, Igneous & Metamorphic Rock

Sedimentary Rock What is it made up of? � Sand, clay, silt, organic matter (fossils) How is it formed (process)? � Weathering (wind, flowing water, ice, living organisms) create sediment � Erosion moves/transports the sediment (water, wind etc. ) � Deposition – sediment is deposited at the bottom of bodies of water � Cementation/lithification – the layers are pressed together (cemented) to form rock

Where are sedimentary rocks formed? �At the bottoms of lakes, rivers, oceans, streams… Examples: Sandstone, limestone, shale Sedimentary rocks are used For: Buildings, statues Video: https: //www. youtube. com/watch? v=e. Ou. Ps. Jw. Yu 9 I

Metamorphic Rock �What is it made up of? � Previous sedimentary and igneous rock � MAY HAVE fossils � Contain layers which look like wavy bands � Hardest rock �How is it formed (process)? � Extreme heat and pressure due to the movement of the Earth’s crust

Where are Metamorphic rocks formed? �Underground in hot temperatures Examples: Slate and marble Metamorphic rocks are used for: Countertops, chalkboards, roof shingles, floors � Video: https: //www. youtube. com/watch? v=e 15 n 7 -zq 0 m. A

Igneous Rock What is it made up of? � Previous sedimentary and metamorphic rock � Intrusive igneous rock- cooled magma � Extrusive igneous rock-cooled lava How is it formed (process)? � When magma and lava cools and hardens � Intrusive – cools slowly and forms large crystals � Extrusive – cools quickly and forms small crystals or none at all

Where are Igneous rocks formed? �Intrusive igneous rock is formed �from magma below ground. �Extrusive igneous rock is formed �from lava above ground. Examples: Intrusive – granite Extrusive - obsidian and pumice Igneous rocks are used for: Intrusive - buildings, countertops, statues Extrusive - arrow heads, sharp blades
