How are oceanic crust and continental crust different?

Oceanic crust is thinner and more dense

What is Plate Tectonics?

Great movements in the lithosphere

What is one of the types of plate boundaries?

Transform Boundary, Convergent Boundary, Divergent Boundary

What happens at divergent boundaries?

Magma rises and new crust forms

Do you feel ready for the test tomorrow?

Yes I do, No, but I am going to study more tonight
