Rocks formed from molten Earth materials are 16______rocks. There are two kinds of molten materials: magma and 17______. 18______and heat caused by overlying rocks and 19______elements produce magma. When magma cools below Earth's Surface, it forms 20______-grained, 21______igneous rocks. The 22______of these common rocks grow large because of the 23______rate of cooling. When magma moves to Earth's 24______, it is called lava. When lava cools on Earth's surface, it forms fine grained, 25______igneous rocks. Minerals of extrusive rocks are so small that 26______is needed for identification. Igneous rocks can be classified by their 27______. They can also be classified by the types of 28______in them.
