What are some differences between Igneous and Metamorphic rocks?
Drupady [299]

Answer:

Igneous rock , formed by the cooling of magma inside the Earth or on the surface.

Metamorphic rocks, formed by temperature and pressure changes inside the Earth.

Explanation:

Igneous and Metamorphic are formed in different ways,

<em>Metamorphic rocks: arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock may be a sedimentary rock, an igneous rock or another older metamorphic rock.</em>

<em>Igneous rocks: began as magma (molten rock) which cooled and crystallized into minerals. This magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.</em>
