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?
what are the main parts of a strato volcano
Composite or Strato Volcanoes.
The textbook answer would be andesite. In reality stratovolcanoes are highly variable and have been known to erupt all of the types of lava observed on modern earth from basalt to rhyolite, sometimes from the same volcano. One stratovolcano even erupts unique carbonatite lava.

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.
