GEOLOGY

Detailed explanation-1: -A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra.

Detailed explanation-2: -Answer and Explanation: Yes, composite volcanoes are explosive. They are cone-shaped and have steep sides where layers of lava, ash, and volcanic debris help form the mountain. Thick and viscous lava comes from composite volcanoes which causes the explosive eruption.

Detailed explanation-3: -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.

Detailed explanation-4: -They are formed from viscous, sticky lava that does not flow easily. The lava therefore builds up around the vent forming a volcano with steep sides. Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma.

Detailed explanation-5: -A Pelean eruption is associated with explosive outbursts that generate pyroclastic flows, dense mixtures of hot volcanic fragments and gas described in the section Lava, gas, and other hazards. Pelean eruptions are named for the destructive eruption of Mount Pelée on the Caribbean island of Martinique in 1902.
