The two main categories of igneous rocks areextrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. Which type ...

Sedimentary rocks are largely formed by erosion of other types of rocks, most drama...
