Question

The giant sea waves generated due to an earthquake on the ocean floor are :

• A. Ocean currents
• B. Tsunami
• C. Tides
• D. Surges

Answer 1

Answer:

B. Tsunami

Tsunami

• A tsunami is a series of massive waves caused by a sudden displacement of a large volume of water. While underwater earthquakes (submarine earthquakes) at tectonic plate boundaries are the most common cause, they can also be triggered by volcanic eruptions or underwater landslides.

• Driven by geological shifts (earthquakes). Unlike normal waves, they involve the movement of the entire water column from the seafloor to the surface.

• Ocean Currents: Driven by gravity, wind (Coriolis effect), and water density (thermohaline circulation). They are like "rivers" flowing within the ocean.

• Tides: Driven by the gravitational pull of the Moon and the Sun.

• Surges (Storm Surges): Driven by extreme wind and low pressure during storms like hurricanes or typhoons.
