what is the difference between Clastic, Chemical and Biochemical sedimentary rocks
Clastic Rocks- broken pieces of minerals and rock fragments that make up sedimentary rocks
Chemical Rocks- form when minerals crystallize directly from water
Biochemical- a sedimentary rock that was formed by organisms or contains the remains of organisms.

What is Metamorphism?
Metamorphism- any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure or the addition of chemical fluids

How do extrusive igneous rocks form?
Extrusive igneous rocks form when lava cools quickly above the surface creating volcanic glass
500
What is the difference between Compaction and Cementation?
Compaction- the weight from layers of sediment forces out fluids and decreases the space between grains
Cementation- when minerals dissolve in water crystallize between sediment grains.
