How Cinder Cone Volcanoes are Formed

Which of the following is an example of a cinder cone volcano?

A. Kilauea
B. Parícutin
C. Himalayas
D. Mount Saint Helens

Fragments of volcanic rock and ash that build up to form cinder cones are known as

A. melting rocks.
B. rising magma.
C. pyroclastic flows.
D. pyroclastic deposits.

Final answer:

Parícutin is an example of a cinder cone volcano. Cinder cones are formed by explosive eruptions and are small in size with steep slopes. The fragments of volcanic rock and ash that build up to form cinder cones are known as pyroclastic deposits.

Explanation:

Of the options provided, B. Parícutin is an example of a cinder cone volcano. Cinder cone volcanoes are formed by explosive eruptions of solid fragments and ash. They are usually small in size and have steep, cone-shaped slopes. Parícutin, located in Mexico, is one of the most well-known examples of a cinder cone volcano.

Fragments of volcanic rock and ash that build up to form cinder cones are known as pyroclastic deposits. These deposits are made up of a mixture of hot rock fragments, ash, and gas that are ejected during volcanic eruptions. Over time, these deposits accumulate and harden, forming the characteristic cone shape of cinder cones.
