How does the cooling rate of igneous rocks relate to their crystal size?
Slower cooling = bigger crystals
Rapid cooling = smaller crystals
How are igneous rocks formed and what are the 2 main types?
Magma cooling and solidifying.
Intrusive and Extrusive.
For sedimentary rock to become metamorphic rock it undergoes change through ________ and _________
Heat and pressure
Example of chemical, biological and physical weathering

How does sediment relate to the formation of sedimentary rocks (describe the process)
Small pieces of sediment build up in layers over time. These layers get pressed down by more layers on top. The pressure and minerals glue the layers together, turning them into solid rock.
Weathering and erosion.
