Answer 1

(B) Its magma has low viscosity

(C) Its lava came from a quiet eruption

(D) Its lava sets fire to everything in its path

Step-by-step explanation:

Answer 2

- Its magma has low viscosity

- Its lava came from a quiet eruption

- Its lava sets fire to everything in its path

Step-by-step explanation:

From this image, we can see that the volcano had an eruption from which it produced lava flows that managed to reach the sea. Since the volcano managed to release such large amount of lava, and the lava managed to pass several km to reach the sea, it means that the magma had low viscosity, thus it is low on silica content. Also, the low viscosity of the magma means that the gases have not been trapped in it, so the eruption of the volcano was a quite one. The lava is very hot, so it manages to set on fire everything on it path, though it immediately moves over the thing it set on fire.
