Section 2 Igneous Rocks and the Geologic History of Your Community
... Magma, Lava, and Igneous Rock Igneous rocks are formed from the cooling of magma. Suppose that you could drill a hole very deep into Earth. You would find that Earth’s temperature initially rises by about 30°C with every kilometer of depth. This rate of increase slows down at deeper depths. At a dep ...

Properties of Minerals
... Minerals can form as hot magma cools deep inside the crust, or as lava hardens on the surface. When these liquids cool to the solid state, they form mineral crystals. The size of these crystals depends on several factors. The rate at which magma cools, the amount of gas magma contains, and the chemi ...
