12. A mining company was comparing rock samples from two different mines. Their observations showed that the rock samples were two different types of rock.
How could energy have played a role in the 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 small 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.
С
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.
d
Energy caused one rock type to form, but not the other. Rock that forms because of energy
is a different type of rock than rock that forms without energy.
