Hank passes a bank made of stone bricks everyday on his way to school. He notices that the stones are made of two different types of rock. How could energy have played a role in different rock types forming?

a) Energy from different sources leads to different types of rock. Energy inside earth melts rock into liquid rock, but energy from the sun causes rock to weather into smaller pieces of rock.

b) energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

c) Energy caused one rock type to firm, but not the other. Rocks that form because of energy are different type of rock than rocks that form without energy.

d) energy changes rock on different continents in different ways. Each continent on Earth has different rock that might form liquid rock or small rock pieces when exposed to energy
