What is frost wedging?
200
Sediments are compacted and cemented together to form this.
What are sedimentary rocks
200
A naturally occurring, inorganic solid with a specific chemical composition and a definite crystalline structure?
What is a mineral.
200
The deepest layer of the earth found 4000 miles beneath the crust made of solid iron and nickel.
What is the inner core.
200
Magma is forced upward toward the crust, magma fills the gap that is created, magma hardens to form new ocean crust.
