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.
A composite volcano is called a "strato" volcano because of its alternating layers of lava flow and volcanic ash, which can resemble the stratified layers of sedimentary rock ("strato" means layers in Latin). This type of volcano is characterized by its steep-sided profile and explosive eruptions.
Strato volcanoes and shield volcanoes are different because of their shape and also because of the may they erupt. Strato volcanoes have steep slopes, shaped like a tall narrow cone.. when a strato volcano erupts vast amounts of gasses such as sulphur dioxide, water and dust are thrown up into the atmosphere. This can cause global warming and pretty sunsets, magma obviously comes out too ( the magma in strato volcanoes is very thick ) . These eruptions are very violent, they can blow up to half of the volcano away leaving a massive crater in the middle of it. Shield volcanoes have gentle slopes, shaped like a low wide cone ( or a shield -hence the name ) when a strato volcano erupts lava fountains can form as hot liquid lava is thrown into the air but these are not usually very high. The lava that comes from shield volcanoes is very runny ( unlike strato volcanoes ) so red hot rivers of lava run down the sides of the volcano. i hope that answered your question. :)
Stratovolcanoes, also known as composite volcanoes, typically consist of alternating layers of solidified lava flows, volcanic ash, and cinders. They also feature a central vent or crater at the summit where eruptions occur. Additionally, stratovolcanoes often have a steep profile due to the viscous magma that tends to solidify quickly.

Mount Shasta and Mount St. Helens are stratovolcanoes, known for their steep-sided cones and explosive eruptions. Mount Fuji is also a stratovolcano but is currently inactive, though it is closely monitored due to its proximity to populated areas in Japan.
by pressure of molten lava of the dence viscocity.
Composite or Strato Volcanoes.
are also known as Strato volcanoes. They are the most common type of volcano, and are formed by explosive eruptions of pyroclastic material followed by a quiet outpouring of lava.
cinder strato and shield shield is the least dangerous and the lava slowly flowsa down cinder erupts tephra not lava like a shield and is cone shaped strato is the most dangerous it erupts both tephra and lava
Is a strato volcano active?

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?)
If it is a big volcanic eruption then it would burn nearby cities and kill people, then it will poison the air with sulfuric acid and darken the sky. Ash will fall from the clouds of the eruption and ruin or collapse buildings because the ash id heavy.
