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.
The melting of metamorphic or igneous rock forms magma.
It will for an intrusive igneous rock. They usually take longer to cool and have more coarse grains.
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 such as granite and basalt can melt under high temperatures when forming. This molten rock, or magma, can then cool and solidify to form igneous rocks.
If sedimentary rock melts and then cools, it can form igneous rock. This process involves the melting of the sedimentary rock due to high temperature and pressure, which leads to the formation of new igneous rock as it cools and solidifies.
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.
Igneous rock is formed when melted minerals cool and harden. This process can happen either beneath the Earth's surface (intrusive igneous rock) or on the surface (extrusive igneous rock). Examples of igneous rocks include granite, basalt, and obsidian.

Igneous Rock.
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.
