What does the rate of cooling determine about igneous rocks?
The rate at which a rock cools will determine its grain or crystal size. Igneous rocks are widely classified into volcanic, hypabyssal and plutonic. Those that cool deep inside the earth are plutonic and those that cool and crystallize at or much near the Earth's surface are volcanic. The intermediate rocks are the hypabyssal ones. Volcanic rocks come immediately in contact with air or water and get quenched developing finer grained crystals that are best identified under a petrological microscope or a high power electron microscope. But plutonic rocks have a hell lot of time to cool due to their hotter surroundings resulting in well grown big crystals, which can usually be identified by naked eye or with the help of a hand lens. You should have now guessed the hypabyssal rocks will have medium sized crystals.
What are types of rocks formed by volcanoes?

And the last one is 3) composite volcanoes; they are medium sized mountains made up of layers of lava that alternates with cinders. That is it.
