Question

which kind of rock requires heat and pressure to form?
igneous rock
clastic rock
metamorphic rock
sedimentary rock

Explanation:

Metamorphic rocks are formed from pre - existing rocks (igneous, sedimentary, or other metamorphic rocks) that are subjected to high heat and pressure. This process causes changes in the mineralogy, texture, and sometimes chemical composition of the original rock. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks form from the accumulation and lithification of sediment (such as fragments of other rocks, minerals, and organic matter). Clastic rocks are a type of sedimentary rock that is composed of fragments (clasts) of pre - existing rocks.

Answer:

metamorphic rock
