1. Rocks are classified as: Sandstone, Slate, Obsidian Hard, shiny, grey Sedimentary, Metamorphic, Igneous Sedimentary, marble, Igneous Basalt 2. Choose the correct statement about rocks. Igneous rocks form when magma cools and hardens. Fossils can be found in Igneous and metamorphic rock. Not usually in sedimentary rock. You can often see sand, pebbles or stones present in Metamorphic rocks. All rocks are hard, grey, and form the same way. 3.Which of the following are all classified as Igneousrocks? (look at journal p.74) Obsidian, Granite, Scoria Conglomerate, Sandstone, Shale Granite, Sandstone, Quartzite Slate, Gneiss, Marble 4.The process in which water, wind and ice weardown rocks and other surfaces is called: Erosion wearation weathering deposition 5.The process where sediments are reduced in volume and are pressed and squeezed into layersis called: pressure packing cementation squishing compaction 6.One process by which Igneous rock can be changedinto Sedimentary rock is: Weathering, erosion, deposition, then heat & pressure. Weathering, erosion, deposition, then compaction & cementation heat & pressure, then melting & cooling melting, then weathering, erosion & deposition 7.Metamorphic rock can change to sediment throughthe process of: Melting, cooling, meling & heat Heat & pressure, then compation & cementation Weathering, heating, melting & compaction Weathering, erosion & deposition 8. Igneous rock can change to Metamorphic rock through the process of: Melting and cooling Heat & pressure, cooling & melting Heat & pressure All of the above |
