Why are composite volcanoes named that?
Stratovolcanoes are also called composite volcanoes because they are built of layers of alternating lava flow, ash and blocks of unmelted stone, according to the U.S. Geological Survey. Stratovolcanoes are considered the most violent.
What are composite volcanoes also known as?
Composite cone volcanoes are also called stratovolcanoes. They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form.
What is the name of a famous composite volcano?
Famous composite volcanoes include Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Shasta and Lassen in California, Mount Hood in Oregon, Mount St. Helens and Mount Rainier in Washington, Mt Pinatubo in the Philipenes, and Mt. Etna in Italy.
What is the characteristics of composite volcano?
The characteristics of composite volcanoes, also known as stratovolcanoes, are: cone shape with steep sides. made of layers of hardened cinder, lava and ash. most violent eruptions of all volcano types.
What best describes a composite volcano?
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity.
Why is Kilauea considered one of the most active volcanoes in the world?
This is because Kilauea is a so-called shield volcano, which is typically broader in shape and has lava that is relatively fluid. Helens in Washington State — are usually taller and have more viscous lava flows with trapped gas that can generate volatile explosions.
What are facts about composite volcanoes?
Composition. Composite volcanoes-also called stratovolcanoes-are named for their composition.
What are the different types of composite volcanoes?
Composite volcanoes are usually found at destructive plate margins. Examples of composite volcanoes include Mount Fuji (Japan), Mount St Helens (USA) and Mount Pinatubo (Philippines). Shield Volcanoes. Shield volcanoes are low with gently sloping sides and are formed from layers of lava.
What are some interesting facts about composite volcanoes?
Composite cone volcanoes are quite large and spread across between one and ten kilometers.
What are the characteristics of a composite volcano?
Composite volcanoes consist of alternating layers of ash and lava flows. Known also as strato volcanoes, their shape is a symmetric cone with steep sides that rise as high as 8,000 feet. They form along Earth’s subduction zones where one tectonic plate pushes beneath another.
