ProfessorStratovolcanoes, 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.

Are cinder cones usually found at the edge of large volcanoes?
Yes, although technically, strato-volcanoes *are* cinder cones (composite cones), built up of layers of ash. But the term "cinder cones" (ash cones) is usually applied to smaller cones that form within the vicinity of large volcanic calderas, such as Crater Lake in Oregon. They may be associated with either strato-volcanoes or shield volcanoes.
Why is another name for composite volcano Strato?
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.
What type of lava do strato volcanoes have?
Strato volcanoes typically have viscous lava with high silica content, known as andesitic or dacitic lava. This type of lava tends to form steep-sided volcanic cones due to its ability to cool and harden quickly, leading to explosive eruptions.
Composite volcanoes are also known as?
stratovolcanoes. They are characterized by their tall, steep-sided profile and explosive eruptions caused by viscous magma. These volcanoes are built up through alternating layers of lava flows, ash, and volcanic rocks.
What type of volcanoes are mount Shasta Mount Fuji and mount St Helen's?
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.
