Answer:

The three primary factors that affect the eruptive styles of volcanoes are:

1. Magma Composition: The chemical composition of magma, particularly its silica content, influences its viscosity. Magma high in silica tends to be more viscous, leading to more explosive eruptions, while magma low in silica is less viscous and results in more effusive, lava-flow eruptions.

2. Gas Content: The amount of dissolved gases (such as water vapor, carbon dioxide, and sulfur dioxide) in the magma affects the eruption style. High gas content can increase pressure within the magma, leading to explosive eruptions, while low gas content typically results in more gentle eruptions.

3. Magma Temperature: The temperature of the magma influences its viscosity. Hotter magma is less viscous and flows more easily, leading to effusive eruptions, while cooler magma is more viscous and can lead to more explosive eruptions due to trapped gases.

These factors interact to determine whether a volcano will have a violent, explosive eruption or a more gentle, lava-flow eruption.
