What do volcanoes blow out?
Lava
Is composite volcano made of entirely running lava?
Shield Volcanoes are made out of running lava. Not composite.
Are composite volcanoes predominantly erupting with lava flows?
No. Composite volcanoes erupt mostly ash and pumice.
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 forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Cinder-Cone Volcanoes and Composite Volcanoes
What is the type of lava in the composite volcanoes?
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.
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
What materials are ejected from andesitic composite volcanoes?
ash and lava
