a clastic rock that has tiny particles of clay
What is shale?

a black(low silica)clastic rock rhymes with bowl
What is coal?
A clastic rock that has angular, gravel sized particles.
What is Breccia?
Rock salt crystallizes from this mineral.
What is Halite?
Running water, rain, wind, ice, and gravity
What are the agents of erosion.
When particle size progressively gets smaller from the bottom to the top (larger particles at the bottom) and they are arranged in horizontal layers.
What is graded bedding?
This is a clastic rock with small particles of sand
What is sandstone
List 2 important organic rocks.
What is coal and limestone?
Rocks that have well-rounded, gravel- sized particles.
What are conglomerates?
The process by which sediments are placed (deposited) in another place by agents of erosion.
What is deposition?
Particles squeezed together under great pressure
What is the definition of compaction?
In this type of rock, the remains of plants and animals are deposited in thick layers.
What is Biochemical rock?
Rocks formed from the remains of once- living organisms.
