Question
**Volcanic Eruption Style Determinants**

**Question:**
The style of volcanic eruption is determined in large part by:

1. the taste of the lava
2. the composition of the lava
3. the gravel content of the lava
4. the depth of the lava

(Note: In this example, the third option 'the gravel content of the lava' is selected, although the scientifically accurate answer should be 'the composition of the lava.')

**Explanation:**
The style of a volcanic eruption, such as whether it will be explosive or effusive, is primarily influenced by the composition of the lava. The silica content, gas content, and temperature of the magma are major factors that determine the eruption style. High silica and gas content typically result in more explosive eruptions, while low silica content leads to more fluid, effusive eruptions. 

**Correct Answer:**
The composition of the lava.

Graph/Diagram Interpretation: There is no graphical or diagram-related content in the image to explain.
