which factors determine the eruptive style of a volcano?
□ depth of magma,
□ magma composition
□ viscosity
□ temperature

Explanation:

The eruptive style of a volcano is determined by multiple factors. The composition of magma (e.g., silica content) affects viscosity. Higher silica makes magma more viscous, leading to explosive eruptions. Viscosity itself (influenced by composition and temperature) impacts how magma flows and erupts. Temperature affects magma's state and flowability. While depth of magma can influence pressure and ascent, it is not a direct primary factor in determining eruptive style compared to composition, viscosity, and temperature.

Answer:

A. temperature, B. viscosity, C. magma composition
