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.
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.
How do composite volcanoes form?
Composite volcanoes form from alternating layers of lava flows, ash, and volcanic rocks that build up over time. This type of volcano is created by a combination of explosive eruptions and lava flows, which allow for the formation of the steep symmetrical shape commonly associated with composite volcanoes.
What volcanoes are formed by explosive eruptions that are followed by lava outpourings?
composite volcanoes

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.

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.
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.
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.
