The Main Types And Features Of Volcanoes Internet Geography

The Main Types And Features Of Volcanoes Internet Geography The main types and features of volcanoes. a volcano is a landform, usually the size of a mountain, that is typically conical and has a cater and vent through which lava, hot gases, steam and rock fragments are or have been erupted through the crust of the earth. at constructive (divergent) plate margins, when two tectonic plates move apart. The main features of a volcano include the magma chamber, vents, craters and slopes. the diagram below shows the main features of a volcano. the magma chamber is a large underground pool of magma. under pressure, the magma in the chamber can rise up the main vent, which is the central tube through the volcano.

What Are The Main Features Of A Volcano Internet Geography Features of volcanoes. crater: the bowl shaped opening at the top of a volcano, where eruptions occur. vent: the channel or opening through which lava and volcanic gases are expelled. magma chamber: an underground reservoir containing molten rock, feeding the volcano. lava flow: the stream of molten rock that flows out during an eruption. The three main types of volcanoes are cinder cones, composite volcanoes (stratovolcanoes) and shield volcanoes. lava domes are a common fourth type of volcano. however, there are other kinds of volcanoes, plus they are compound or complex volcanoes that have features of multiple types. for example, trident volcano in alaska is a complex volcano. A crater can sit at the top of a volcano and is the location where much of the lava, gas, rock fragments and ash are ejected from. figure \(\pageindex{1}\): mt. st. helens last major eruption left the huge crater seen in the center of the photograph. (courtesy usgs cvo) lateral vents are found on the sides of some volcanoes where lava is extruded. 6.12: types of volcanoes. a volcano is a vent through which molten rock and gas escape from a magma chamber and they can differ in height, shape, and slope steepness. some volcanoes are tall cones and others are just cracks in the ground. as you might expect, the shape of a volcano is related to the composition of its magma.

A pyroclastic flow is a superheated mixture of hot steam, ash, rock and dust. a pyroclastic flow can travel down the side of a volcano at very high speeds with temperatures over 400 degrees celsius. composite volcanoes can rise over 8000 feet. a simple cross section of a composite volcano. when composite volcanoes erupt they are explosive and.
