GEOLOGY

Detailed explanation-1: -Cinder cones may form by themselves or when new vents open on larger, existing volcanoes. Mauna Kea, a volcano on the American island of Hawaii, and Mount Etna, a volcano on the Italian island of Sicily, are both covered with hundreds of cinder cones.

Detailed explanation-2: -Cinder cones usually erupt lava flows, either through a breach on one side of the crater or from a vent located on a flank.

Detailed explanation-3: -Unlike shield volcanoes, composite volcanoes have a distinctly conical shape, with sides that steepen toward the summit. Cinder cones are the smallest, and almost too small to see next to a volcano like Mauna Loa.

Detailed explanation-4: -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.
