What are the 7 types of volcanoes?

The result is the classic cone shape of composite volcanoes. A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow, (7) vent, (8) lava, (9) ash cloud.

What are the 11 types of volcanoes?

What are the Different Types of Volcanoes?

• Cinder Cone Volcanoes: These are the simplest type of volcano.
• Composite Volcanoes: Composite volcanoes, or stratovolcanoes make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example.
• Shield Volcanoes:
• Lava Domes:

Is Yellowstone a composite volcano?

Whats hotter fire or lava?

While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.

What kind of material is ejected from a volcano?

Material explosively ejected from a volcano. The ascending, vertical part of the mass of erupting debris and volcanic gas that rises directly above a volcanic vent. Higher in the atmosphere, columns usually spread laterally into plumes or umbrella clouds.

What kind of rock is formed by a volcano?

Fine fragments (less than 2-4 mm in diameter) of volcanic rock formed by a volcanic explosion or ejection from a volcanic vent. Volcanic rock (or lava) that characteristically is dark in color (gray to black), contains 45 to 53 percent silica, and is rich in iron and magnesium.

What kind of rock is lava made of?

Volcanic rock (or lava) that characteristically is light in color and contains 62 to 69 percent silica and moderate amounts of sodium and potassium. Moving masses of rock, soil and snow that occur when the flank of a mountain or volcano collapses and slides downslope.

Which is the best synonym for a volcano?

Synonym is stratovolcano. A dome-shaped volcano constructed of multiple lava domes and flows. Volcanic rock (or lava) that characteristically is light in color and contains 62 to 69 percent silica and moderate amounts of sodium and potassium.
