Question

Explain the difference between how intrusive and extrusive igneous rock form and how those formation processes affect the minerals in these rock.

Answer 1

Extrusive molten rocks are formed from lava while the intrusive molten rocks are formed from magma.

Explanation:

Extrusive molten rocks originate from lava, framing at the outside of the Earth and cooling rapidly, which means they structure little precious stones. Intrusive volcanic rocks originate from magma, shaping profound underground and taking more time to cool, which means they structure bigger crystals.

Intrusive molten rocks are framed when magma cools gradually underneath the surface, while extrusive rocks are shaped when magma cools quickly at the surface.
