volcanoes earthquakes new rock is formed layers rise to the surface
I gave my students this multiple choice question: When buried sediments are subjected to pressure, the mineral grains are squeezed together. What is the result of this action?

Only one answer is correct among these 4 choices:
- volcanoes
- earthquakes
- new rock is formed
- layers rise to the surface

Could you tell me which one is correct?

new rock is formed
