__________ rocks forms when a rock is changed by heart,pressure, or chemical reactions.

a) Igneous
b) Sedimentary
c) Metamorphic
d) Chemical

i think its c

Right.

thanks Ms. Sue i just posted another question do you think you could help me with that? then i'll leave you alone. :)

wait is it C? I'm confused >_<

You are correct! The type of rock that forms when a rock is changed by heat, pressure, or chemical reactions is called metamorphic rock.

To determine the correct answer, it is helpful to understand the three main types of rocks: igneous, sedimentary, and metamorphic.

- Igneous rock is formed from the solidification of molten magma. This can happen either above the Earth's surface, where it is called extrusive, or below the surface, where it is called intrusive.

- Sedimentary rock is formed through the accumulation and compaction of sediment, which can include fragments of other rocks, minerals, or organic matter. This process typically occurs near the Earth's surface.

- Metamorphic rock, on the other hand, is formed when pre-existing rocks (igneous, sedimentary, or other metamorphic rocks) go through changes due to intense heat, pressure, or chemical activity. These changes cause the minerals within the rock to recrystallize, resulting in a new rock with a different structure and sometimes different minerals.

Therefore, in this case, the correct answer is c) Metamorphic, as the rock in question is being changed by heat, pressure, or chemical reactions.
