What are Stratovolcanoes?

Answer 1

stratovolcano is a tall, conical mountain (volcano) composed of both hardened lava and volcanic ash. The shape of these volcanos is characteristically steep in profile because the lava flows that formed these volcanos were highly viscous, and so cooled and hardened before spreading very far. Such lava are classed as acidic to be high in silica. At the other end of the spectrum are shield volcanoes (such as Mauna Loa in Hawaii), which are formed from less viscous, basic lavas (high in metals such as magnesium and iron), giving them a wide base and more gently sloping profile. Many stratovolcanos exceed a height of 2500 m. They are often created by subduction of tectonic plates.

Although stratovolcanoes are sometimes called composite volcanoes, volcanologists prefer to use the term stratovolcano to distinguish among volcanoes because all volcanoes of any size have a composite (layered) structure — that is, are built up from sequential outpourings of eruptive materials.

Answer 2

Stratovolcanos are ones that have alternating layers of composition, typically andesite and another rock such as dacite. Mount Saint Helens is an example of a stratovolcano.

Answer 3

Stratovolcanoes, also known as composite cones, are the most picturesque and the most deadly of the volcano types. Mt. Fuji is one of them

Answer 4

A stratovolcano (also composite cone or composite volcano) is a tall, conical mountain (volcano) composed of both hardened lava and volcanic ash. The shape of these volcanoes is characteristically steep in profile because lava flows that formed them were highly viscous, and so cooled and hardened before spreading very far. Such lava tends to be high in silica. At the other end of the spectrum are shield volcanoes (such as Mauna Loa in Hawai'i), which are formed from less viscous lavas, giving them a wide base and more gently sloping profile. Many exceed a height of 2500m. Stratovolcanoes are often created by subduction of tectonic plates.
Because all volcanoes of any size have a stratified (layered) structure — that is, are built up from sequential outpourings of eruptive materials — volcanologists prefer to use the term stratovolcano for these mountains.Examples of stratovolcanoes are:

Cotopaxi in Ecuador
Mount Erebus in Antarctica
Mount Fuji in Japan
Mount Hood in north Oregon state in the United States
Kolló´´¡dyngja in North-East Iceland
Mayon Volcano in the Philippines
El Misti in Southern Peru's city of Arequipa
Mount Rainier in the north-central Washington state in the United States
Mount Ruapehu in New Zealand's North Island
Mount Shasta in northern California state in the United States
Soufriere Hills volcano on the Caribbean island of Montserrat
Mount Spurr in Alaska state in the United States
Mount St. Helens in southern Washington state in the United States
Mount Tambora Sambawa Island, Indonesia
Mount Taranaki (formerly Mount Egmont) in New Zealand's North Island
Teide on Tenerife, Canary Islands, Spain
Tr?dyngja in North-East Iceland
Mount Vesuvius near Naples, Italy
