Most composite volcanoes are comprised of Andesitic lava. Andesetic lava has an intermediate silica content compared to granitic with a high silica content and basaltic with a low silica content.

Does a composite volcano have an Aa type of lava?
A'a can occur at composite volcanoes, but block lava flows, which are far more viscous, are more common.
What are the 4 types of volcanoes which exist and what type of lava do they produce?
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
What volcanoes are formed by explosive eruptions that are followed by lava outpourings?
composite volcanoes
What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Cinder-Cone Volcanoes and Composite Volcanoes
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.

shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
Are composite volcanoes predominantly erupting with lava flows?
No. Composite volcanoes erupt mostly ash and pumice.
Is composite volcano made of entirely running lava?
Shield Volcanoes are made out of running lava. Not composite.
Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Aa and pahoehoe lavas are both basaltic in composition. The lava from composite volcanoes is likely to be granitic.
What volcanoes are formed by explosive eruptions that are followed by lava outpourings?
composite volcanoes
What are the three types volcano?
A shield volcano, cinder cone volcano, and the composite volcano. Shield volcanoes are on of the three types of volcanoes. Shield volcanoes have quiet eruptions and the lava is basaltic. Its slope is shallow compared to a composite volcano and a cinder-cone volcano. They are produced by hotspots and mid-ocean ridge. Cinder-cone volcanoes are the second of the three types of volcanoes. Cinder-cone volcanoes. Cinder-cone volcanoes have explosive eruptions that release lava high in the air. They are created by tephra, volcanic ash. Its slope ranges between 30 degrees and 40 degrees. The lava is andesitic. Composite volcanoes are the third type of volcanoes. Their eruptions vary from loud and explosive to quiet. Composite volcanoes cab rise as high as 8000 feet and are steep. An example of composite volcanoes is Mount Fuji. Composite volcanoes spew felsic lava and they are built up by layers of harden lava, tephra, pumice, and volcanic ash.
What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Cinder-Cone Volcanoes and Composite Volcanoes
Four landforms created from lava and ash?
Three landforms that can be created from ash are cinder cone volcanoes, composite volcanoes, and shield volcanoes. Lava plateaus can also be formed.
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
How is hawaiian lava different from composite cone lava?
Compared with the lava in composite volcanoes, hawaiian lava has a slow silica content, is runny, and erupts at a higher temperature.
What is the consistency of lava in the composite volcanoes?
Composite volcanoes are found on destructive plate margins , where the oceanic crust sinks beneath the continental crust. Composite volcanoes have the following characteristics: Acidic lava, which is very viscous (sticky). Steep sides as the lava doesn't flow very far before it solidifies
