These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
100

These 2 things form metamorphic rocks

The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
200

This is what happens to the density and color as a rock becomes more mafic (must address both).

What is the density gets higher and the color gets darker?

These are two ways that sediments are formed.

What is weathering and erosion?

200

This type of metamorphism does not occur from pressure and happens over a short area.

500

This is the difference between high grade metamorphism and low grade metamorphism.

What is that high grade metamorphism has a higher temperature and pressure than low grade?
