Answer:
Extrusive igneous rocks come from lava, forming at the surface of the Earth and cooling quickly, meaning they form very small crystals. Intrusive igneous rocks come from magma, forming deep underground and taking longer to cool, meaning they form larger crystals.
Explanation:
If magma takes hundreds of years to cool into rock, the mineral crystals within the rock most likely will be large.
All igneous rocks are formed from magma, which is a naturally occurring substance that is molten or semi-molten.
The Earth possesses magma beneath its surface, and other terrestrial planets and several naturally occurring satellites have also been confirmed to have magmatic activity.
Magma may also include gas bubbles and suspended crystals in addition to molten rock.
Rock is a solid mineral component that is present on the earth's surface or beneath the soil. Rocks are created in the earth's crust.
According to geology, rocks are created when one or more minerals are combined.
For instance, the minerals quartz, feldspar, and biotite make up granite.
