1: Minerals You can tell minerals from rocks because of some characteristics of minerals are: They are usually shiny, they usually have a luster, they are usually hard, they are sometimes dark, and they usually do not have layers.
2: minerals some mineral tests are cleavage, luster, acid, mass, and hardness
4: Igneous Rocks Igneous rocks are formed through lava and magma. They form in a range of 45 seconds to 1000 years. Igneous rocks are usually smooth. There are two types of igneous rocks. They are extrusive and intrusive. | Obsidian | Pumice | Granite
5: Metamorphic Rocks Metamorphic rocks are formed through tons of heat and pressure. They have very compact layers. You can tell metamorphic rocks from sedimentary rocks because sedimentary rocks have fossils and pebbles in them. There are two types of metamorphic rocks. They are foliated and nonfoliated. | Marble | Schist | Slate
6: Sedimentary Rocks Sedimentary rocks are a type of rock that is made by a lot of pressure and heat. You can tell sedimentary rocks from metamorphic rocks because sedimentary rocks have fossils and pebbles in them. There are two types of sedimentary rocks. They are clastic and organic. | Sandstone | Limestone | Shale
7: A rock is a mixture of 2 or more minerals.
9: The Rock Cycle is a cycle of which rocks turn into each other. A few examples of how rocks can change into each other are: erosion, heat and pressure, and weathering.
