Description

Rocks that solidified from a hot, molten matrix such as Magma or Lava. When the magma cools slowly, individual components can crystalline and form coarse-grain rocks, such as Granite, Diorite, Basalt, and Syenite. When the magma or lava cools quickly, fine-grain minerals and glass-like rocks, such as Rhyolite and Obsidian, are formed.
