Detailed explanation-1: -Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Detailed explanation-2: -Stratovolcano: A large, steep-sided, symmetrical cone built of alternating layers (strata) of lava, ash, cinders, blocks, and bombs. Also called composite volcano, these stratovolcanoes form some of Earth’s grandest mountains rising as much as 8, 000 feet above their bases (movie).
Detailed explanation-3: -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-4: -Cinder Cones Cinder refers to the pyroclastic fragments, which is composed of rock. Cinder cones are also known as ash cones. 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.
Detailed explanation-5: -Cinder cones get their name from the material that forms them, cinders. Cinder cones are the simplest volcanic formation. They form from explosions of red, hot magma cinders and ash. These cinders and ash settle around the main vent and build a steep sided cone.
