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
