Question

the rock cycle describes the formation, breakdown and reformation of rocks. it includes many processes that move and shape earths materials.
after an igneous rock forms, it can melt into magma and then cool into a new igneous rock.
or, weathering and erosion can break it into sediments that create a sedimentary rock.
otherwise, it may be heated and/or put under pressure, transforming into a metamorphic rock.
like igneous rocks, a metamorphic rock can break down into sediment and then become part of a sedimentary rock. a metamorphic rock can also melt into molten rock and cool into an igneous rock.
if exposed to wind and water, a sedimentary rock can become sediment again. that sediment might be eroded, deposited and compacted as a new sedimentary rock. or, like igneous rock, a sedimentary rock can be heated and put under pressure to become a metamorphic rock.
which of the following is true?
choose one option
a igneous rock can melt and cool to form new igneous rock.
b igneous rock can break into sediments that will form a sedimentary rock.
c metamorphic rock can break into sediments that form sedimentary rock.
d all of the above.

Explanation:

• Option A: The text states “After an igneous rock forms, it can melt into magma and then cool into a new igneous rock.” This matches the description in Option A.
• Option B: The text says “weathering and erosion can break it (igneous rock) into sediments that create a sedimentary rock.” So, igneous rock can break into sediments (though it's the sediments that form sedimentary rock, not directly stated as “will form” in a strict sense here, but the process of breaking into sediments is correct).
• Option C: The text mentions “Like igneous rocks, a metamorphic rock can break down into sediment”.

Answer:

D. All of the above.
