Which of the following statements about the viscosity of lavas is true?

Question

Quizplus · Accepted Answer

The viscosity of lava is directly related to its silica content. Lava with a high silica content will have a higher viscosity, making it thicker and less fluid. This is because the silica molecules tend to become intertwined, creating a more complex structure that resists flow. Conversely, lava with a lower silica content will have a lower viscosity and will be more fluid.
