Select all the properties of a shield volcano listed below.
a. basaltic lava
b. violent eruptions
c. layered structure
d. found around the ring of fire
e. large amounts of pyroclastic material

Option (A), (C) and (D)

Explanation:

Shield volcanoes are generally characterized gentle slopes, and are dome shaped, resembling the shield that is used by the ancient warriors. This type of volcano produces magma that are basaltic in nature and have no silica content. So they can flow easily. The layers are often formed due to the gentle eruption of lava that solidifies. These volcanoes are not explosive but they can turn into a violent one if it comes in contact with water. They occur along the Pacific's ring of fire. The amount of pyroclastic materials is less than the total amount of lava it releases during a volcanic eruption.

Thus, the correct answers are options (A), (C) and (D).
