Is mount tambora an explosive volcano?
No, Mt. Stromboli is a very active Volcano.
A steep-sided volcano formed entirely of ash and cinders is a?
A Stratovolcano is a steep volcano made mostly of layers of ash, lava and cinders. Stratovolcanoes have a tendency to be very explosive and produce significant quantities of ash.
Does a composite volcano erupt quietly or explosively?
A composite volcano is the most explosive type of volcano there is. Mt. St. Helens and Mt.Vesuvious in Pompeii are both examples of composite volcanoes, and look at the damage they did. a composite volcano usually has pyroclastic flows to accompany the traditional lava and ash.
How does cider cone volcano and shield volcano differ?
Cinder cones are small and steep-sloped, composed of volcanic cinders, and have mildly explosive eruptions. Shield volcanoes are large and shallow-sloped with very runny lava and generally non-explosive eruptions.
What is the difference between composite volcano and cinder volcano?
A shield volcano is made from lava flows that flow far, making a very wide, not very steep mountain. A cinder cone volcano is the most common type of volcano. It is formed from volcanic fragments and is very steep sided, although not always extremely tall. They usually have just one main vent, and can also sometimes form from a vent of a larger volcano, growing and becoming a whole new volcano. Composite volcanoes resemble very large cinder cone volcanoes at first, but have bigger particles making them up usually and also have multiple vents more often. They also are potentially more explosive.
What type of lava does an explosive eruption produce?
An explosive eruption typically produces thick and sticky lava known as silica-rich or felsic lava. This type of lava has high viscosity and trapped gas bubbles, causing it to erupt violently. As the lava is very viscous, it can block and build pressure in the volcano, resulting in explosive eruptions.
Why doesn't a volcano mountain explode everyday if the lava is always hot?
There are several reasons. First, there isn't always magma (what lava is called when it is underground). The magma is usually trapped far below the volcano, unless the volcano is erupting or about to erupt. Second, heat alone cannot create an explosion. An explosion requires rapid expansion. Explosive volcanic eruptions occur when gas trapped in the magma is suddenly released as pressure on the magma decreases, or when water flash boils on contact with lava or magma. If there is no gas, and no water, there cannot be an explosive eruption. Third, the kinds of magma most likely to cause explosive eruptions are very viscous, meaning they do not flow very easily. As a result, they tend to get "stuck." Finally, the poper term is "erupt" not "explode" as not all eruptions are explosive. If there is not enough gas the volcano will ooze out lava rather than causing an explosion.
How does a volcano cause a lot of damage?
when it erupts the lava can flow to places and the ash cloud and gases from the volcano are very dangerous for humans.
What is different between cinder cone volcano and shield volcano?

Which type of volcano forms a large cone-shaped mountain from alternating layers of lava flow and volcanic ash?
A volcano that forms very large lava flows and builds itself up that way is known as a shield volcano. This type of volcano may not always erupt from a central summit vent but can have satellite vents (Rift Zones) that will form long channels of lava flows going down the slopes. These volcanoes are often times known as erupting in a very placid style and although can have explosive eruptions are very very rare. A volcano of this type would be either KIlauea or Mauna Loa on the big island of hawaii.
Why does a runny volcano not explode?
The explosive force of an explosive eruption comes from gasses trapped in the magma. Runny magma does not hold gasses very well, and so those gasses escape before the magma erupts. The runny magma can also easily flow to the surface without getting stuck and having to be blown out, unlike thicker types of magma.
What is the difference between composite and cinder cone volcanoes?
