Solution
The forceful ejection of magma during a volcanic eruption is driven by the rapid expansion of gases in the magma. Here's a step-by-step explanation:
-
Magma is formed when the earth's mantle melts. This magma contains dissolved gases, which are held in the magma due to the high pressure deep within the earth.
-
When the magma rises towards the surface, the pressure decreases. This causes the dissolved gases to expand.
-
The expansion of gases propels the magma out of the volcano in a forceful eruption.
So, the correct answer from the given choices is "rapid expansion of gases in the magma".
