What are igneous extrusions?
== == Extrusive igneous rocks are formed from the solidification of lava on or above the surface. Rapid cooling from exposure to air or water results in rapid crystallization of their component minerals, normally creating a fine grained texture as opposed to intrusive igneous rocks which have a coarser texture. Examples of extrusive igneous rocks would include obsidian, pumice, basalt, and rhyolite.

What do a entrusive ingneous look like?
I think it is "extrusive Igneous rock". Well, the magma,the hot liquid earth material which flows out through a vent(ways or cracks in the earth's crust), if on coming over to the surface of the earth, cools or solidifies, it is called "extrusive rock". If the magma, cools before coming over to the surface of the earth it is called "intrusive rock". the rocks formed this way are generally Igneous rocks. More detailed answer may follow.
