Question

Which option is true about the formation of volcanic mountains?

• A. Formed by upliftment of land due to interior volcanic movements.
• B. Formed by constant ejection and cooling down of lava.
• C. Formed by the collision of tectonic plates.
• D. Formed by upliftment of land due to tectonic plate movements.

Answer 1

The correct option is B Formed by constant ejection and cooling down of lava.

The volcanic mountains are formed by solidification of lava ejected from the Earth's surface. The constant ejection and solidification of lava leads to the formation of a cone around the volcano known as the volcanic mountains. Magma is molten rocks and metals within the Earth and is known as lava when it erupts out of the Earth's surface.
