1 A rock is a mixture of minerals and possibly organic material.
2 The continuous process that turns one rock into another.
3 Rocks are classified by their composition and texture along with the process that forms them.
4 Igneous rocks are formed from magma or lave cooling.
5 Intrusive igneous rocks cool slowly inside the earth creating course crystals and extrusive igneous rocks cool
fast on the surface of the earth with fine or no crystals.
6 Sedimentary rocks form from weathering, erosion, deposition, compaction, and cementation.
7 Clastic – sediments compacted together, chemical – formed from evaporation, and organic – made from once
living things
8 Metamorphic rocks form from heat, pressure, and chemical reactions.
9 The two classes of metamorphic rocks are foliated, layers or bands of minerals, and unfoliated, no layering or
bands.
10 Weathering is the breaking down of rocks
11 Mechanical weathering breaks rocks down into smaller size pieces. Chemical weathering changes the
chemical properties of the rock.
12 Erosion is the transportation of rock sediments
13 Wind, running water, glaciers, waves, and gravity
14 Deposition is where the rock sediments get laid to rest.
15 Contact metamorphism happens when rocks come in close quarters to magma plumes. Regional
metamorphism occurs in greater areas deep in the Earth’s crust.
16 Mafic igneous rocks are darker in color, contain heavier elements like iron, and denser. Felsic igneous rocks
are lighter in color, contain lighter elements like silicon, and less dense.
