Which Rock Cooled The Fastest. The rhyolite cooled rapidly, and the granite cooled slowly. The faster magma or lava cools, the smaller the crystals it contains. This occurs when a rock has a mixed cooling. Igneous rocks that cool on earth’s surface are extrusive and do not have a crystalline structure because they cool quickly. The first pair is two rocks that formed from a felsic magma. Crystal size is a function of cooling rate. If magma cools quickly, for example when basalt lava. A common igneous rock rule is that if lava cools at a faster rate, the rock formed will have finer grains and have a glassy appearance; Porphyritic rock is a type that has a combination of large and small grains; Cooling rate and gas content create a variety of rock textures. These rocks form when magma erupts onto the earth’s surface, where it is called lava, and cools rapidly. Extrusive igneous rocks cool much more rapidly than intrusive rocks, reducing the time for crystal structure to form within the rocks. It is possible for lava to cool so rapidly that no crystals can form. The second pair is two rocks that formed from mafic magma. Sometimes, when cool, sticky magma erupts, the lava solidifies too rapidly for crystals to form and so volcanic glass (obsidian) is produced.

A common igneous rock rule is that if lava cools at a faster rate, the rock formed will have finer grains and have a glassy appearance; These rocks form when magma erupts onto the earth’s surface, where it is called lava, and cools rapidly. When lava erupts onto the surface or rises into shallow in a mountain and cools, the rock that will cool from it is called an extrusive igneous rock. The first pair is two rocks that formed from a felsic magma. If rock cools at a slower rate, the grains will be larger and more coarse. The second pair is two rocks that formed from mafic magma.
