Epicenter
What is the process that breaks rocks into smaller pieces?
Weathering
What is a crack in Earth’s crust called?

What is one way the rock cycle changes rocks over time?
Erosion
What word means "experiencing something personally, not secondhand?"
Firsthand
What causes volcanoes and hot springs to form beneath Earth’s surface?

What happens to the seafloor when one plate slides under another?
An oceanic trench forms
