Question 15(Multiple Choice Worth 3 points) W Which of the following is not commonly associated with a plate boundary? fault hot spot O mid-ocean ridge O mountain trench

Answer 1

Answer:

Option (1)

Explanation:

Hotspots are the regions where the magma rises towards the surface due to the presence of large mantle plumes. The force exerted by the magma here is very high. When the lithospheric plates move over these regions, the magma comes out to the surface forming volcanoes. And as the plates move away from the region of hotspot they eventually cool. These hots spots are fixed at a place. There are numerous hotspots on earth.  for example, the Hawaiin island chain, below which there are regions of hotspots.

Thus, the hotspot regions are not associated with the plate boundaries.

Hence, the correct answer is option (1).
