VOLCANOES

RIZTIE RABACAL'S GEOLOGIC STUDIES


VOLCANO

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface

SUNSET CRATER IS A CINDER CONE VOCANO
Mauna Loa IS A SHEILD VOLCANO


  • TYPES OF VOLCANOES
  • stratovolcano (or composite volcano) — a conical volcano consisting of layers of solid lava flows mixed with layers of other rock
  • cinder cone volcano — doesn’t have any horizontal layers, and is instead a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from the vent.
  • shield volcano —  a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.
SUPERVOLCANO
An unusually large volcano having the potential to produce an eruption with major effects on the global climate and ecosystem.

YELLOWSTONE IS A SUPERVOLCANO

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. A large number of submarine volcanoes are located near areas of tectonic plate movement, known as mid-ocean ridges.
