Question

1. hank passes by a building every day on his way to school. he notices that the rock used to build the walls of the building is a different type than the rock used to build the steps. 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 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 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.

Explanation:

Energy from different sources leads to different types of rock. Energy inside the Earth (like heat and pressure) can melt rock into liquid rock (magma/lava), which forms igneous rocks when it cools. Energy from the Sun causes processes like weathering (physical, chemical, biological) that break rocks into smaller pieces. These smaller pieces can then be compacted and cemented to form sedimentary rocks. So, different energy sources (internal - Earth's heat; external - Sun's energy) play roles in forming different rock types.

Answer:

A. Energy from different sources leads to different types of rock. Energy inside the Earth melts rock into liquid rock, but energy from the Sun causes rock to weather into small pieces of rock.
