GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Composite volcanoes are also called stratovolcanoes. This is because they are formed by alternating layers (strata) of magma and ash (Figure below). The magma that creates composite volcanoes tends to be thick.

Detailed explanation-3: -A composite volcano is a symmetrical cone with steep sides that are built of alternating layers of lava, ash, pumice, blocks, and tephra.

Detailed explanation-4: -Stratovolcano is a volcano constructed of alternating layers of lava flows and pyroclastic rocks.

Detailed explanation-5: -Composite cone volcanoes are also called stratovolcanoes. They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up.
