100
Materials that settle out of water and/or air

What is metamorphism?
100
Melted rock inside Earth
What is magma?
200
Set of natural processes that form, change, break down, and reform rocks
What is the rock cycle?
200
Forms when lava cools on Earth's surface
What is an extrusive igneous rock?
200
These two elements transport or carry sediment to places where rocks are formed
What are wind and water?
200
Process by which pressure and heat can break bonds of atoms in minerals and then new bonds form to make new minerals
What is recrystallization?
200
Most common rock at Earth's surface
What are sedimentary rocks?
300
Forms when molten rock cools into a solid
What is an igneous rock?
300
Slow cooling time allows these to form to a large size
What are crystals?
300
Unusual sedimentary rock made from the remains of plants
What is coal?
300
Arrangement of minerals in flat or wavy bands
What is foliation?
300
Limestone is this type of rock
What is a sedimentary rock?
400
Forms when pieces of older rocks, plants, and other loose material get pressed together
What is a sedimentary rock?
400
Lava that contains a large amount of this flows slowly
What is silica?
400
This sedimentary rock is formed from the shells and skeletons of ocean organisms
What is limestone?
400
Nonfoliated rock often used by artists because it won't shatter; it is easiest of rock to sculpt
What is marble?
400
Lava rich in silica forms this shape volcano
What is a cone-shaped volcano?
500
Forms when heat and/or pressure causes older rocks to change into new types of rocks
What is a metamorphic rock?
500
One of three markings on a sandstone which indicate the action of past wind or water currents
What are crossbeds, ripples, and mud cracks?
500
Changes in metamorphic rocks over a large area can push these up onto Earth's surface
