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 is the type of lava in the composite volcanoes?
Composite volcanoes typically erupt with a mixture of lava types, including both viscous lava (andesitic or rhyolitic) that can lead to explosive eruptions, as well as more fluid lava (basaltic) that can flow long distances. This combination of lava types is what gives composite volcanoes their steep-sided profile.
What volcanoes are formed by explosive eruptions that are followed by lava outpourings?
composite volcanoes
Composite volcanoes such as Mount Rainier in Washington are formed from what type of lava?
Composite volcanoes are primarily formed from andesitic lava, which is thicker and more viscous than basaltic lava. This leads to a build-up of pressure and explosive eruptions, creating the classic cone shape of composite volcanoes.
What are three types of volcanoes?
Three types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while stratovolcanoes are characterized by alternating layers of lava and ash. Cinder cone volcanoes are small, steep-sided volcanoes formed by pyroclastic material ejected during eruptions.
Do composite cone volcanoes have mafic lava?
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
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.

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.
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.

Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.
Do composite volcanoes blow out smoke and ash or lava?
ash
What are six landforms from lava and ash?
I only know four they are shield volcanoes, composite volcanoes, and lava plateaus thats all I know
