3. A volcanologist discovers a volcano built from alternating layers of lava flow, ash, and cinders.

Composite volcano

Explanation:

Composite volcanoes are also known as stratovolcanoes. They are characterized by their steep sides and symmetrical features. These types of volcanoes are built slowly from the alternating layers of lava flow, ash and cinders erupting from the conduit system, which accumulate and add to the slopes of the volcano.
