Did you know that composite volcanoes make up 60% of the Earths volcanoes. Composite volcanoes don't always have to erupt from the top. They can have many magma chambers and can erupt from the sides. They can be made of basalt, rhyolite and/or andesite. They erupt both ash and lava. The lava is very thick. When the time comes for the volcano to erupt they start to become very quiet. (Sneaky eh?)
Is a strato volcano active?
Composite or Strato Volcanoes.
A strato-volcano, also known as a composite volcano, is made from alternating layers of solidified lava flows, volcanic ash, and other volcanic debris. These layers are built up over time as the volcano continues to erupt, creating the classic cone shape associated with strato-volcanoes.
No. Volcanoes erupt.
About 60 volcanoes erupt each year.
An unlimited amount of volcanoes can erupt at once
Volcanoes can erupt at any time of year.
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
Strato and Cinder-cone volcanos but cinder cones can have non explosive too but not strato
Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
Yes, they are.
