Question

1. jasmine travels a lot and collects rocks wherever she goes. she was examining two rocks from her collection, and she noticed that they are different types of rock. how could energy have played a role in the different rock types forming?

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.
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.
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.
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.

Explanation:

• Option a: Incorrect. The type of rock - forming process (not the continent) determines how energy affects rock.
• Option b: Incorrect. All rock - forming processes involve energy.
• Option c: Correct. Igneous rocks form from the melting of rock due to internal Earth energy (magma/lava). Sedimentary rocks start with weathering (caused by solar - powered processes like wind, water) of pre - existing rocks into small pieces.
• Option d: Incorrect. Energy changes igneous rock from magma/lava (when it cools) but sedimentary rock forms from the compaction and cementation of small rock pieces (which are created by weathering, often a solar - related process), not just energy changing sedimentary rock into small pieces.

Answer:

C. 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.
