100
This is the study of rocks
What is geology

This is made of solid iron and nickel.
What is the inner core.

This says that rocks that are cut by a fault or piece of igneous rock are older than what cut them.
What is the law of cross cutting relationships
300
Volcanic islands are found at this type of boundary

This law says that a layer that has inclusions of another layer must be younger than the layer that it the inclusions came from
What is the law of inclusions
400
Rift valleys are formed at this plate boundary
What is continent-continent divergence?

How do volcanoe and asteroids cause extinctions?
What is, they send debris into the air which block out the sun. This causes producers to be unable to make glucose, which impacts the whole food web.

What is difference between oceanic and continental crust?
What is oceanic crust is younger, thinner, and more dense. Continental crust is older, thicker, and less dense.
