GEOLOGY

Detailed explanation-1: -Cinder cones are the smallest and most common type of volcano. Cinder cones have steep sides like composite volcanoes. But they are much smaller, rarely reaching even 300 meters in height. Cinder cones usually have a crater at the summit.

Detailed explanation-2: -Cinder cones are the most common type of volcano. A cinder cone has a cone shape, but is much smaller than a composite volcano. Cinder cones rarely reach 300 meters in height but they have steep sides.

Detailed explanation-3: -Cinder cones rarely reach 300 meters in height but they have steep sides. Cinder cones grow rapidly, usually from a single eruption cycle (Figure below). Cinder cones are composed of small fragments of rock, such as pumice, piled on top of one another.

Detailed explanation-4: -Cinder cones are the smallest, and almost too small to see next to a volcano like Mauna Loa.

Detailed explanation-5: -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.
