3.1 The Rock Cycle !. 3.1 Rock Cycle. Interactions among water, air, and land can cause rocks to change from one type to another. The continuous processes that cause rocks to change make up the ROCK CYCLE. Main Idea: Rocks get around and recycle!. 3.1 The Rock Cycle.

Shows the interrelationships among the three rock types(igneous, sedimentary, and metamorphic)
Magma is molten material that forms deep beneath the Earth’s surface.
Lava is magma that reaches the surface.
Weathering is a process in which rocks are broken down by water, air, and living things.
Sediment is weathered pieces of Earth elements.
how the rocks are formed!!!
Metamorphic rocks are formed under the surface of the earth (from meta=change; morpho=form).
Metamorphic rock is either igneous or sedimentary rock that (under incredible pressure and heat) gets baked. This pressure and heat rearranges the atoms of the mineral.
Minerals are defined by their physical and chemical properties. There are several common characteristics that we will use in our rock lab.
Mineral fluorescence takes place when the incoming ultraviolet energy is absorbed by a mineral and is immediately given off as visible light.
Under ultraviolet light.
With regular visible light.
