A continuous process that causes rock to change from one form to another. 2. Rock Any solid mass of minerals or mineral-like matter 3. Do most rocks occur as one mineral or as a mixture of minerals? 4. Some rocks are made of non- mineral material, can you name one? Coal Draw the rock cycle in your science notebook The Rock Cycle is a group of changes, this change does not necessarily have to be a chemical change. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Almost all of rock today that we have on earth is made up of all the same stuff as the rocks that dinosaurs and other ancient life forms walked, crawled, or swam over Over time rocks are recycled into other rocks Moving tectonic plates are responsible for destroying and forming many types of rocks List the 3 types of rocks List the 3 types of rocks In what ways are the two rocks similar? Look at the granite rock and the rhyolite rock GraniteRhyolite 15. In what ways are the two rocks different? GraniteRhyolite Granite coarse texture, made from magma Rhyolite fine texture, made from lava 16. What causes the two rocks to be different? GraniteRhyolite Granite Slow cooling below the earths surface Rhyolite Quick cooling on the earths surface Classifying Rocks Rocks can be classified by looking at the rocks texture, mineral composition, and color. Slow cooling magma will form rocks with a a. coarse grained texture. b. fine grained texture. c. glassy texture. d. porphyritic texture. Question What is texture? The size, shape, and pattern of the rocks grain (nice) Glassy The minerals that make up the different parts of a rock Composition (what it is made of?) Examples are: Quartz Feldspar Magnesium Iron Bet Cha Werent Expecting A. POP QUIZ!!!!!* WW hat are the three types of rock? WW hich type of rock has been formed by magma or lava?
