Take a look at these awesome Rocks and Mineral websites!
Here are some important vocabulary words we will be using throughout this unit. I will be adding to the list in about a week. This week in class, we will be taking notes on them so everyone will have a study guide to take home.There will be a quiz over these terms later on, but start studying now!!!!
metamorphic rocks-rocks formed when heat and pressure change one kind of rock into another.
sedimentary rocks- rocks formed over time by the hardening of layers of sediment like mud, shell particles, pieces of bone, and rock fragments.
igneous rocks- rocks that are formed when melted rock cools and hardens, either under or above the surface.
lava- molten rock found on top of Earth's crust
magma- molten rock underground
minerals- solid, pure substances found in the Earth that combine to form rocks. Minerals are made by a process deep within the Earth.
