Question

question 10 not yet answered points out of 5 flag question the viscosity of magma is directly related to: select one: a. the depth at which it is created b. its silica content c. the size of vent through which it erupts d. the age of the overlying rock

Explanation:

Magma's viscosity is mainly determined by its silica content. Higher silica - rich magma has higher viscosity as the silica chains can impede the flow of magma. Depth, vent size, and age of overlying rock do not directly determine viscosity.

Answer:

B. Its silica content
