Question

1. what three things influence how explosive a volcanic eruption can be?

Explanation:

The explosiveness of a volcanic eruption is influenced by three main factors. First, the viscosity of the magma. Magma with high viscosity (thick and sticky) traps gases more easily, leading to more explosive eruptions. Second, the gas content in the magma. A higher gas content (such as water vapor, carbon dioxide, and sulfur dioxide) means more gas pressure builds up, increasing the potential for an explosive eruption. Third, the silica content in the magma. Magma with a high silica content is more viscous, which as mentioned before, contributes to a more explosive eruption.

Answer:

The three things that influence how explosive a volcanic eruption can be are: magma viscosity, gas content in the magma, and silica content in the magma.
