Igneous rocks are formed from the solidification of lava or magma . When an igneous rock cools and hardens above ground, it cools quickly, resulting in a little to no grained rock. This is called an extrusive rock. An example of an extrusive rock is obsidian. When an igneous rock forms below ground, it cools slowly, resulting in a well developed mineral composition, with large crystals. Granite is an example of an intrusiveigneous rock.

Which is older igneous or sedimentary?
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks.
