the techtonic plates collide together making one side push upwards out of the ground and then the lava flows out
magma flows up to form the eruption
it was formed by the eruption of a volcano
Any kind of volcano can form after the eruption. If it doesn't erupt and never has then it isn't a volcano.
A combination volcano develops from repeated lava eruptions and the accompanying tephra deposits Tephra is the debris from the eruption..
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.
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
A volcano eruption can cause an earthquake and or aftershocks
An eruption from the side of a volcano is called a lateral eruption. This usually happens at rift zones where a volcano breaks apart. It is also called a flank eruption. If the volcano is explosive, it may also be called a lateral blast.
A dormant volcano is a volcano which has had an eruption but it was a long time ago. It is a volcano which shows no sign of activity or a future eruption. Basically, a dormant volcano is a volcano which is asleep.
its an eruption which is quiet.
The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption
Cotopaxi volcano is in Ecuador. A volcano magma can be measured during and after volcano eruption. The Cotopaxi eruption in 1987, its lahar has travelled for 60 miles.
