Question

the image shows a volcano erupting at night in russia. which label best describes this image?
○ explosive eruption—beware of ash!
○ gases push out magma with great force!
○ volcano quietly erupts due to low - viscosity magma!
○ high silica content of magma results in lava reaching sea level by morning!

Explanation:

The image shows a slow-moving lava flow, not an explosive eruption (which would have ash/violent gas expulsion). Low-viscosity magma flows easily, causing quiet, gentle eruptions like the one depicted. High silica magma is high-viscosity, leading to explosive activity, which is not seen here.

Answer:

C. Volcano quietly erupts due to low-viscosity magma!
