What is the name of the towering volcanoes that form from both lava flows and cinder rocks?

A.

cinder cone volcanoes

B.

composite volcanoes

C.

mountain volcanoes

D.

shield volcanoes, I believe the answer is C, correct me if i'm wrong :)

Final answer:

The name of the towering volcanoes that form from both lava flows and cinder rocks is 'composite volcanoes'. They are characterized by steep, conical profiles and are found in subduction zones, where they allow us to study materials from deep within the Earth.

Explanation:

The towering volcanoes that are characterized by layers of hardened lava flows intermixed with layers of ash and other volcanic debris are known as composite volcanoes. Often found in regions of subduction where one tectonic plate slides beneath another, composite volcanoes are also associated with regions where continental plates collide. These volcanoes provide valuable insight as they allow us to sample materials from deeper parts of our planet's interior.

Due to their structure, composite volcanoes may have highly explosive eruptions and can be quite dangerous due to their tendency to produce both pyroclastic flows and lahar mudflows. The materials that form these volcanoes, like tuff, are often ejected during these explosive eruptions. Over time, the alternating layers of lava and ash create the steep, conical profile that we associate with these towering geologic features.

Which type of volcanoes are characterized by layers of hardened lava flows intermixed with layers of ash and other volcanic debris? Composite volcanoes.
