Which of the following is true about volcanic mountains? volcanic mountains form on land but not on the ocean floor. volcanic mountains form on land as well as on the ocean floor. volcanic mountains form on the ocean floor but not on land. volcanic mountains can form on the ocean floor but never build up above sea level.

Option (2)

Explanation:

The volcanic mountains are referred to as those mountains that are formed from volcanic activities. These are formed adjacent to the convergent plate boundaries. This could be due to the convergence of an oceanic and a continental plate or it could be due to the convergence of two oceanic plates.

In this type of plate boundary, the heavier plate goes down relative to the lighter plate, thereby resulting in the formation of a subduction zone and above this zone, there lies a long narrow depression which is commonly known as the trench.

As the heavy plate subducts, it melts and reacts with the magma. This magma then rises up towards the over-riding plate, giving rise to the formation of volcanoes or volcanic or island arcs. These are known as the volcanic mountains.

Thus, the volcanic mountains are formed both on the land and on the ocean floor.

Hence, the correct answer is option (2).
