magma
Actually, it is called intrusive rock and not platonic rock. Intrusive rock forms from magma that solidifies beneath the Earth's surface, while extrusive rock forms from lava that solidifies on the Earth's surface.
When magma solidifies before reaching Earth's surface it is called intrusive igneous rock, plutonic rock, a pluton. Igneous rock is formed from crystallization of molten magma.
IT IS CALLED INTRUSIVE (PLUTONIC) ROCKS WHICH ARE BELOW THE SURFACE. iT IS WHEN MAGMA COOLS AND SOLIDIFIES WITHIN THE EARTH.They are called intrusive igneous rocks or plutonic rocks/plutons.
The most common plutonic igneous rock is granite. There are various types of granite based on whether the rock cooled above or below the surface of the earth. The major differences among these types of granitic rock is their crystalline structure.
A plutonic dome is found in areas of flat-lying sedimentary rocks that sloped up to create a roughly circular shape. Its core is made up of plutonic or igneous rocks that arched up the overlying sedimentary layers.
When molten rock solidifies it forms igneous rock.
A plutonic intrusion.Igneous rock.
Plutonic intrusion refers to the process by which molten rock (magma) is forced into pre-existing rock formations beneath the Earth's surface. As the magma cools and solidifies underground, it forms intrusive igneous rocks, such as granite. These rocks can later be exposed at the surface through processes like erosion.
Cooled magma is turned into a plutonic igneous rock, eg. Granite (you can see the difference between plutonic and volcanic because plutonic have large crystal particles)
plutonic and volcanic
Plutonic rock tends to have large crystals because it solidifies deep underground, where the overlying material insulates it so that it cools slowly, allowing time for large crystals to form. Volcanic rock tends to have small crystals (or to be amorphous) because it solidifies above ground, where air and water can cool it quickly by convection. Rapid cooling does not allow time for crystals to grow large. Plastic rock I don't know about.
