Which type of volcano has a steep cone-shaped hill or mountain made with only pyroclastic flow?
A
Cinder cone volcano
B
Shield volcano
C
Composite volcano
D
Earthquake
Explanation: 

Detailed explanation-1: -Cinder cones are simple volcanoes which have a bowl-shaped crater at the summit and steep sides. They only grow to about a thousand feet, the size of a hill. They usually are created of eruptions from a single opening, unlike a strato-volcano or shield volcano which can erupt from many different openings.

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: -Cinder Cones (Fig. 5.12) are built from pyroclastic debris that accumulates around the vent of an explosive volcano. The sides are composed of layers of pyroclastic deposits.

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.

Detailed explanation-5: -Cinder cones are the most common type of volcano in the world. They may look like an idealized depiction of a volcano as they are steep, conical hills that usually have a prominent crater at the top. Cinders at Capulin Volcano. Cinders are small chunks of scoria.
