Learning Objective
I can analyze the interactions between tectonic, weathering, and erosional processes in shaping Earth's surface.
- 1
Minerals are inorganic, naturally occurring chemical compounds with a crystalline structure, while rocks are solid collections of minerals.
- 2
Igneous rocks make up about 90 percent of the Earth’s crust and are formed from the cooling and solidification of magma or lava.
- 3
The pressure from the weight of overlying material compacts, cements, and transforms sediments into sedimentary rock, while intense temperature and pressure changes cause existing rock to undergo metamorphism and change into a completely new metamorphic rock type.
