When magma cools close to the earth's surface, as in the case of volcanic eruptions, more rapid cooling creates smaller crystals. These rocks are classified as extrusive igneous rocks. Examples include granite, obsidian and pumice. Sedimentary rocks Sedimentary rocks are created by the accumulation ...
Igneous Rock When magma (the molten liquid inside of volcanoes) cools, it forms igneous rock. Though their formation may be similar, igneous rocks can look and feel quite different. Phaneritic rocks are coarse, while aphanitic rocks have a much finer grain and are smoother. ...
type of rock, the other two being igneous and sedimentary. Because of how they are formed, metamorphic rocks constitute a great deal of the bedrock in Earth's crust. Many precious materials, such as marble and many types of gemstones, including diamonds, are formed by the metamorphic process...
The sapphire and ruby crystals that form inside these rocks are usually quite small and getting them out of these rocks is an expensive and long process that often results in broken crystals. Luckily the corundum is even harder and the gems have been working their way free through weathering ...
The thinner parts are the oceanic crust, which underlies the ocean basins at a depth of 5-10 km (~3-6 miles), while the thicker crust is the continental crust. Whereas the oceanic crust is composed of dense material such as iron magnesium silicate igneous rocks (like basalt), the contine...

What type of rocks recrystallize to form metamorphic rocks? What process creates metamorphic rocks? What are biochemical sedimentary rocks? What are the most common minerals in granite and basalt? What mineral group is feldspar in? How does a sedimentary rock become an igneous rock?
