EARTHQUAKES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A strong earthquake that occurs on the ocean floor could result in the formation of
A
an ocean current
B
El Nino
C
a delta
D
a tsunami
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: -If the earthquake occurs in the ocean, it can push up powerful waves, known as tsunamis. The sudden upward or downward movement of the seafloor during an earthquake creates large tsunami waves, similar to a child splashing in the bathtub.

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.

Detailed explanation-4: -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-5: -Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults. These tsunami-generating earthquakes originate mainly in subduction zones, where tectonic plates collide and one is forced under the other.
