GEOLOGY

Detailed explanation-1: -Cinder cones are the simplest volcano type. They are characterized by a cone shape, steep slopes, and small size. They are also the most common volcanoes. Cinder cones are formed by the accumulation of ejected igneous rocks called cinders that form the slopes.

Detailed explanation-2: -Stratovolcano. 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 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-4: -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-5: -There are three basic cone shapes and six eruption types. The three cone shapes are cinder cones, shield cones, and composite cones or stratovolcanoes. The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.
