Interesting fact: Volcanoes are found not only on Earth but on other planets and satellites in our solar system. Images and data from space probes have revealed that the moon, Mars, Venus, and possibly Mercury all have a history of volcanic activity, although none appear to have active volcanoes. One of the largest extraterrestrial volcanoes is Olympus Mons, on Mars. This extinct volcano is about 17 miles (27 kilometers) high and 373 miles (600 kilometers) across. Scientists have discovered active volcanoes on Lo, a satellite of Jupiter, and on Triton, a satellite of Neptune.
A volcano is a place where molten rock, pieces of hot solid rock, and hot gases formed inside the earth erupt through its surface.
Volcanic activity is the most dramatic and rapid of all geologic processes that shape the surface of the earth.
There are four different types of volcanoes. There are stratovolcanoes, shield volcanoes, cinder cone volcanoes, and ashflow calderas volcanoes.
Stratovolcanoes, or composite volcanoes, get their name from different layers, or strata, of ash and lava that form them.
Shield volcanoes, formed when large flows of lava spread rapidly from central vents or rows of vents, are the largest volcanoes.
Cinder cone volcanoes are the most common type of volcano on the earth's surface.
Ashflow calderas volcanoes produce the most explosive eruptions on earth.
