Igneous rocks form when magma or lava cools and hardens into a rock. Magma and lava are rocks that are so hot they move like a liquid. Magma is molten rock that is underground; lava is molten rock that is above the ground â and that is the only difference between them.A common igneous rock is granite.gneous rocks form when magma or lava cools and hardens into a rock.

As the rock cycle illustrates, rocks can form in a wide assortment of geologic settings. Rocks differ in their mineral composition and their rock texture. Texture (the size, shape, and distribution of particles that collectively constitute the rock) is a function of the geologic processes related to a rock's formation.For instance, granite is an intrusive igneous rock in which the mineral grains display visible crystal surfaces.owever, discussions below on rocks and minerals, plate tectonics, the evolution of life, and the stratigraphic record have a New York City orientation; for the sake of brevity the discussion is both limited and generalized.
