Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Undersea earthquakes can cause a sudden drop or rise in the ocean floor creating a ____
A
hurricane
B
tsunami
C
P wave
D
S wave
Explanation: 

Detailed explanation-1: -When a sudden displacement of a large volume of water occurs, or if the sea floor is suddenly raised or dropped by an earthquake, big tsunami waves can be formed. The waves travel out of the area of origin and can be extremely dangerous and damaging when they reach the shore.

Detailed explanation-2: -More than 80% of the world’s tsunamis occur in the Pacific along its Ring of Fire subduction zones. When a great earthquake ruptures, the faulting can cause vertical slip that is large enough to disturb the overlying ocean, thus generating a tsunami that will travel outwards in all directions.

Detailed explanation-3: -A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Detailed explanation-4: -The plates meet with each other, and if rough spots cause the movement to stop at the edges, the motion of the plates continue. When the rough spots can no longer hold, the sudden release of the built-up motion releases, and the sudden movement under the sea floor causes a submarine earthquake.
