Magma that reaches the surface is referred to as lava.
magma that has reached the earth's surface tends to cool faster, that is why the rock will have more holes in it than a rock that has not reached the earth's surface. magma that has cooled enough to become a rock is known as a igneous rock. but there are two types of igneous rock. ther is intrusive igneous and extrusive igneous. intrusive is when the magma has cooled on the inside. this rock will have large crystals because it has cooled slower and most likely it will have a fine grained texture. extrusive igneous is when magma has reached earths surface (thats when it becomes lava) and has cooled. these rock with either have very small microscopic crystals or no crystals at all because the lava cools so quickly that they do not have enough time to really form.
