GEOLOGY

Detailed explanation-1: -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-2: -Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes. 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.

Detailed explanation-3: -Cinder cones are more technically known as scoria cones. Scoria are irregularly-shaped, highly vesicular (bubble-shaped cavities) fragments of lava that are erupted into the air and are typically solid when they land.

Detailed explanation-4: -Cinder cones are small volcanoes that consist of volcanic ash, cinders, and other types of tephra that has piled up around a vent. Cinder cones are typically built in a single eruptive period that lasts a few months and that may include the eruption of fluid lava flows from vents located along the base.
