5. 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?

Question

Responses

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 response that accurately explains how energy can play a role in the formation of different rock types 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 response appropriately identifies the different sources of energy (geothermal and solar) and correlates them with the processes that lead to the formation of different rock types, such as igneous and sedimentary rocks.
