A Tsunami is caused by rapid and violent winds moving in the same direction to push the water towards land, creating large waves that moves away from the event.

A Tsunami is caused by the moon coming very close to the Earth, creating extreme high tides, and with the help of wind, creating tsunamis.

A Tsunami is usually occurs following an earthquake, but could also occur following landslides on the seafloor, land slumping into the ocean, major volcanic eruptions or large meteorite impacts. The large slabs of rock suddenly move which causes the water to move, creating large waves that moves away from the event.

None of the above

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: -A tsunami is caused by a large and sudden displacement of the ocean. Large earthquakes below or near the ocean floor are the most common cause, but landslides, volcanic activity, certain types of weather, and near earth objects (e.g., asteroids, comets) can also cause tsunamis.
Detailed explanation-3: -How are Tsunami generated? A Tsunami can be generated only through the vertical movement of the seafloor. Most Tsunamis are generated by earthquakes. Volcanic eruption, underwater explosion, landslides and meteorite impacts are some other causes of Tsunami.
Detailed explanation-4: -Tsunamis can be generated when a landslide displaces the water from above (subaerial) or below (submarine). Tsunami generation depends on the amount of landslide material that displaces the water, the speed it is moving, and the depth it moves to.
Detailed explanation-5: -The phenomenon we call tsunami is a series of large waves of extremely long wavelength and period usually generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.
