A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around , travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to and are up to high.

which of the following is not generally a factor in wave generation in the open ocean UNANSWERABLE what is the definition of 'sea'? The sea, the world ocean, or simply the ocean is the connected body of salty water that covers over 70% of Earth's surface. what is meant by 'seawater'? It is water in the sea a characteristic of seawater is that it is salty. how do waves form? Wind blowing over the surface of a body of water forms waves that are perpendicular to the direction of the wind.
