Question

which process will transform a metamorphic rock into an igneous rock? compression under intense pressure over time melting due to high temperatures weathering into much smaller particles deposition from sediment within a river

Explanation:

Igneous rocks form from the cooling and solidification of magma or lava. Metamorphic rocks need to melt due to high - temperatures to become magma or lava first, which then cools to form igneous rocks. Compression forms other metamorphic rocks, weathering breaks rocks into smaller pieces for sedimentary rock formation, and deposition is related to sedimentary rock formation.

Answer:

Melting due to high temperatures
