Question

2. Stonemasons work with rock, cutting it into shapes to use for building. One stonemason was unloading a new delivery of rocks and noticed that the delivery contained two different types of rock.

How could energy have played a role in the different rock types forming?

Responses

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 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.

c
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.

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.

Answer 1

The best response that accurately addresses how energy plays a role in different rock types forming is:

**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.

This option correctly explains that different energy sources (geothermal energy from within the Earth and solar energy from the sun) contribute to the formation and alteration of various types of rocks, highlighting the processes involved in both igneous and sedimentary rock formation.
