Question

1. volcanic eruptions often occur (4 points)

under the plates
in the air
along the belts called the ring of fire
in lakes

1. select all the pressures involved in a volcanic activity (4 points)

lithostatic pressure
asthenostatic pressure
atmospheric pressure
magmastatic pressure

Explanation:

1. The Ring of Fire is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur. Volcanic eruptions are not common in the air, lakes or just randomly under the plates in general.
2. Lithostatic pressure is the pressure exerted by the weight of overlying rocks. Magmastatic pressure is related to the pressure of the magma. Atmospheric pressure also plays a role in volcanic activity as it affects how easily magma can erupt. Asthenostatic pressure is not a typical pressure term related to volcanic activity.

Answer:

1. C. along the belts called the ring of fire
2. lithostatic pressure, atmospheric pressure, magmastatic pressure
