Which of the following best describes the behavior of silica rich magma
a. highly viscous and associated with violent eruptions
b. highly viscous and associated with quiet volcanic eruptions
c. stays deep within earth because of low viscosity
d. cannot flow but is limited to fixed areas of hotspot volcanism

A. Highly viscous and associated with violent eruptions

Explanation:

Most silica rich magma have high viscosity and huge amount of trapped gases within them. As they continue to upwell and expand, the gases causes violent eruptions near Volcanoes. Most granitic/rhyolitic magma are silica rich.

answer; /// i believe that the correct answer is (c)
