• Composition – chemical make up of rock; can be minerals

or other materials.

• Texture – size, shape, and position of the grains that make up the rock.

• Rock Cycle- the continual process by which

new rock forms from old rock.

• Weathering - rocks broken into sediments

• Erosion - sediments moved

• Deposition - sediments dropped

Made of: volcanic material

Intrusive – formed below Earth’s surface

(magma) Cools slowly, large crystals

Extrusive – formed above Earth’s surface

(Lava). Cools Fast, Small Crystals

Granite, obsidian, basalt

Made by: cooling magma/lava

How are sedimentary rocks formed?

Look at the layers!
