What types of rocks would be common in a composite volcano?
A) felsic and intermediate lava flows
B) pyroclastic rocks from an eruption column
C) pyroclastic rocks from pyroclastic flows
D) rocks with fragments formed by landslides and mudflows
E) all of these
Composite Volcano
A type of volcano built from alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs, typically steep-sided and explosive.
Pyroclastic Rocks
Formed from volcanic eruptions, these rocks are made up of volcanic ash, dust, and debris.
Felsic Lava
Lava that is high in silica content, leading to high viscosity and explosive volcanic eruptions.

Final Answer :
E
Explanation :
Composite volcanoes, also known as stratovolcanoes, are characterized by a variety of eruption styles and magma types, leading to the formation of felsic and intermediate lava flows, pyroclastic rocks from both eruption columns and pyroclastic flows, and rocks formed by secondary processes such as landslides and mudflows.
