3. Mauna Loa
The largest volcano in the world is Mauna Loa. It has a volume of about 40,000 cubic kilometers, and an above-sea level area of 5125 square kilometers (these values come from an article by Jack Lockwood and Peter Lipman in U.S. Geological Survey Professional Paper #1350, pages 509-535).
4. Fault
In geology, fracture in the rocks of the Earth's crust, where compressional or tensional forces cause the rocks on the opposite sides of the fracture, or fault, to be displaced relative to each other.
5. Volcanic rock
is an igneous rock of volcanic origin.
Volcanic rocks are usually fine-grained or aphanitic to glassy in texture. They often contain clasts of other rocks and phenocrysts. Phenocrysts are crystals that are larger than the matrix and are identifiable with the unaided eye. They were created during fractional crystallization of magma before extrusion. Rhomb porphyry is an example with large rhomb shaped phenocrysts enbedded in a very fine grained matrix.
