Where are igneous rocks mostly commonly found?
Where Igneous Rocks Are Found. The deep seafloor (the oceanic crust) is made almost entirely of basaltic rocks, with peridotite underneath in the mantle. Basalts are also erupted above the Earth’s great subduction zones, either in volcanic island arcs or along the edges of continents.
Are igneous rocks common everywhere?
Igneous rocks are everywhere! One of the most common igneous rocks that make up the crust is granite. Many mountain ranges are made of granite.

What does igneous rock have large crystals?
Igneous rocks are called intrusive or plutonic when they cool and solidify beneath the surface. Because they form within the Earth, cooling occurs slowly. Such slow cooling allows time for large crystals to form, therefore, intrusive or plutonic igneous rocks have relatively large mineral crystals that are easy to see.
What are the physical properties of igneous rocks?
The prime characteristics of igneous rocks used for identification purposes are color and size of crystals. Color of igneous rocks may be light or dark, whereas the crystal size is either small or large, based on how crystallization process takes place.
What is the process of igneous rock?
In essence, igneous rocks are formed through the cooling and solidification of magma ( or lava). As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize. All told, there are over 700 known types of igneous rock,…
