The type of igneous rock that takes the longest time to cool is metamorphic. This is mainly due to the fact that they made from a combination of all the other rocks.
A metamorphic rock can melt into magma and then cool and crystallize to become an igneous rock. Or, a sedimentary rock (or sediments) can melt into magma and then cool and crystallize to become an igneous rock. Also, an igneous rock itself can undergo this process of melting and cooling as well.
Igneous rock.
Metamorphic because they use different minerals to form
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
An igneous rock's crystal size is dependent on how long it takes to cool from magma into a solid. Intrusive igneous rocks, the ones that solidify from magma underground, are slow to harden, giving crystals plenty of time to grow larger. Extrusive igneous rocks, formed from lava above ground, cool fairly rapidly, not allowing the crystals much time to grow in size.
Igneous rocks that cool under the Earth's surface. They are called intrusive rocks.
Old, cool igneous rock sinks.
It becomes a Igneous rock.
The sedimentary rocks would have to melt and cool again to make an igneous rock.

An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
intrusive igneous rock
No, first it has to melt, then erupt, and then it has to cool down. When it solidifies completely, it becomes an igneous rock.
magma cools into intrusive igneous rock while lava into extrusive igneous rock
