GEOLOGY

Detailed explanation-1: -Composite cones are large volcanoes (many thousands of feet or meters tall) generally composed of lava flows, pyroclastic deposits, and mudflow (lahar) deposits, as well as lava domes. Composite volcanoes are active over long periods (tens to hundreds of thousands of years), and erupt periodically.

Detailed explanation-2: -A composite volcano, or stratovolcano, is a type of volcano characterized by a tall, cone shape that results from periodic explosive eruptions that deposit layers of ash, lava, and pyroclastic material. The tallest volcanoes in the world are composite volcanoes for this reason.

Detailed explanation-3: -Composite volcano facts Composite volcanoes form in subduction zones when an oceanic plate subducts beneath a continental plate. The volcanoes often contain more than one type of lava. Andesite is the main type of lava that creates stratovolcanoes. Stratovolcano is another name for composite volcanoes.

Detailed explanation-4: -Composite volcanoes are tall, symetrically shaped, with steep sides, sometimes rising 10, 000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders. Famous composite volcanoes include Mount Fuji in Japan, Mount Shasta and Mount Lassen in California, Mount St.
