Question

Dr. Laszlo and his colleague Dr. Obasi are studying two different rock samples of different types of rock. How could energy have played a role in the different rock types forming?
A.
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.
B.
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.
C.
Energy changes rock in different ways, depending on the starting rock type. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.
D.
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.

Answer 1

The best answer is:

**D. 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.**

This option accurately describes how different energy sources (like heat from within the Earth and sunlight) contribute to the formation and alteration of different rock types. Melting due to geothermal energy leads to igneous rocks, while weathering and erosion driven by solar energy can lead to sedimentary rocks.
