Question

1. reina is making museum exhibits about two different rock types. how could en played a role in the different rock types forming?

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.
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.
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:

• Option a: Igneous rock is formed from liquid rock (magma/lava), not changed into liquid rock. Sedimentary rock is formed from small pieces of rock (sediments) cemented together, not just changed into small pieces.
• Option b: All rock types (igneous, sedimentary, metamorphic) form because of energy. For example, igneous from heat (energy) inside Earth melting rock, sedimentary from processes like weathering (involves energy from sun etc. for temperature changes causing weathering) and cementation (involves chemical energy in some cases), metamorphic from heat and pressure (energy).
• Option c: Energy inside Earth (geothermal energy) can melt rock into liquid rock (magma). Energy from the sun causes temperature changes that lead to physical weathering (e.g., expansion and contraction of rocks due to heating and cooling) which breaks rocks into small pieces. This is a correct description of how energy from different sources (internal - Earth's heat; external - solar energy) leads to different rock - related processes (formation of igneous - from melted rock; formation of sediments for sedimentary - from weathering).
• Option d: The type of rock and how energy affects it is not mainly determined by the continent. It is more about the source of energy (internal or external) and the rock - forming processes.

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.
