How are stratovolcanoes different from shield volcanoes?

Answer 1

Strato volcanoes and shield volcanoes are different because of their shape and also because of the may they erupt.

Strato volcanoes have steep slopes, shaped like a tall narrow cone.. when a strato volcano erupts vast amounts of gasses such as sulphur dioxide, water and dust are thrown up into the atmosphere. This can cause global warming and pretty sunsets, magma obviously comes out too ( the magma in strato volcanoes is very thick ) . These eruptions are very violent, they can blow up to half of the volcano away leaving a massive crater in the middle of it.

Shield volcanoes have gentle slopes, shaped like a low wide cone ( or a shield -hence the name ) when a strato volcano erupts lava fountains can form as hot liquid lava is thrown into the air but these are not usually very high. The lava that comes from shield volcanoes is very runny ( unlike strato volcanoes ) so red hot rivers of lava run down the sides of the volcano.

i hope that answered your question. :)

Answer 2

The difference between a strato volcano and a shield volcano can be found in their structure, and many other characteristics. Please read the explanation below:

Shield Volcanoes:

These types of volcanoes are formed when lava pouring out from a vent hardens on top of a previous layer of hardened lava. Over time, a wide, slightly sloping mountain (as shown in the picture above) is formed: a shield volcano. Shield volcanoes rising over hotspots formed the islands of Hawaii.

Answer 3

No. A stratovolcano is a large volcano with steep slopes composed of ash and lava flows, mostly from high viscosity material. Such volcanoes are prone to highly explosive eruptions.
A shield volcano is a large volcano with shallow slopes composed of flows of low-viscosity lava. Such volcanoes usually do not have explosive eruptions.

Answer 4

Stratovolcanoes are steep-sloped volcanoes composed of layers of ash, tuff, and lava flows. They can erupt a wide virtually any type of volcanic material, ranging from basalt, to rhyolite, and even carbonatite. They often have different phases of activity, sometimes producing explosive pyroclastic eruptions, and somtimes producing simple lava flows.

Shield volcanoes are borad-sloped volcanoes composed of layers of sucessive lava flows. They exclusively erupt basaltic lava. Sheild volcanoes generally erupt non-explosively, with lava either oozing or fountaining out and the flowing downhill. Occasionally there can be explosions if water comes in contact with the magma, but this is rather rare.

Answer 5

A shield volcano is a large volcano with broad slopes at a low angle. They are composed primarily cooled lava flows of basalt, a dark, dense volcanic rock with a low silica content. Most eruptions from these volcanoes ooze or fountain lava and are not explosive.

A stratovolcano is a large, steepsloped volcano composes of layers formed by lava flows and ash deposits. These volcanoes vary in the kind of activity and the composition of the material they produce, but it most often has a moderate to high silica content. These volcanoes often erupt explosively, producing large clouds of ash. Lava flows may also develop at some times.

Answer 6

Dome volcanoes are tall and are not broad where as shield volcanoes are broad and low.
