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. Famous composite volcanoes include Mount Fuji in Japan, Mount Shasta and Mount Lassen in California, Mount St.

Detailed explanation-2: -Cinder conesCinder cones, sometimes called scoria cones or pyroclastic cones, are the most common types of volcanic cones. They form after violent eruptions blow lava fragments into the air, which then solidify and fall as cinders around the volcanic vent.

Detailed explanation-3: -The slopes of stratovolcanoes are therefore composed of lava flows alternating with layers of pyroclastic deposits. Stratovolcanoes have steeper slopes than shield volcanoes and are common along convergent plate boundaries (Fig.

Detailed explanation-4: -Cinder cones are the type of volcano that is formed by pyroclastic fragments like volcanic ashes, solidified lava pieces, volcanic clinkers, pumice and hot gases. These volcanoes are formed around the volcanic vent and are known to be the simplest form of a volcano.

Detailed explanation-5: -Stratovolcanoes (Composite Volcanoes) The stratovolcanoes are made up of layers of lava flows interlayed with sand-or gravel-like volcanic rock called cinders or volcanic ash. These volcano land formations are typically 10-20 miles across and up to 10, 000 or more feet tall.
