Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.

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.
The columbus plates are what caused this volcano to form.
Because when the volcano erupts it lets all the hot volcanic acid and lava out of the ground making the earth's surface cooler.
Just use cardboard as the base. Cut slightly triangular sections of cardboard out of a cardboard box and tape together to form a cone shape. If it is irregular so much the better as it will look more natural. Use strips of papier mache to cover the form completely. If you are making a volcano, leave the top and bottom open to do the volcano thing.
Mount Pinatubo is a composite volcano, also known as a stratovolcano. It is characterized by its steep symmetrical cone shape and explosive eruptions caused by the combination of lava flows and pyroclastic material.
A combination volcano develops from repeated lava eruptions and the accompanying tephra deposits Tephra is the debris from the eruption..
A cinder cone volcano forms from tephra eruptions. Tephra consists of volcanic matter like ash, cinders, and volcanic rocks exploded into the air during an eruption, which then settle around the vent to form a steep-sided cone-shaped structure.
The volcano eruption was when the layers of the earth crack..and it form into a volcanic cone,thats where the lava comes out...and the volcano is build by the lava,is because that every time the lava turns cold it drys..and becomes hardend
Mount Etna is a Composite Volcano.
A cinder cone volcano can form relatively quickly, typically in a matter of a few months to a few years. This type of volcano usually erupts intermittently, with each eruption depositing layers of ash, cinder, and lava that build up the cone shape over time.
Not really. While there is nothing that would prevent a composite volcano from developing under an area where a pond happens to be, there is no pond big enough to contain a composite volcano. As soon as the volcano starts forming, the first significant eruption would probably fill in or blast away the pond.
Krakatoa is a volcanic island with a caldera volcano. The caldera was formed during the catastrophic eruption in 1883, which caused the island to collapse and form a large caldera. Today, Krakatoa is composed of three main volcanic cones within the caldera.
Cinder cone volcanoes form from the accumulation of cinders and tephra during an explosive volcanic eruption. This material is ejected from the volcano and falls around the vent, building up a cone-shaped structure. Examples of cinder cone volcanoes include Paricutin in Mexico and Sunset Crater in Arizona.
Mauna Loa is a shield volcano. It is one of the largest in the world and is characterized by its gentle sloping sides built up from numerous lava flows. Shield volcanoes are primarily composed of basaltic lava.

Mount Mayon, the Phillipines, is a stratovolcano, or a composite volcano. The lava erupted has a high silica content and high viscosity, and is mainly andesitic. Mount Mayon is categorised as active, and is viewed as a 'perfect volcano' due to the symmetry of sides.
