Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
A tsunami (plural: tsunamis or tsunami; from Japanese: æ´¥æ³¢, lit. harbor wave; English pronunciation: /tsuËËnÉËmi/) , also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.arthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.
* A tsunami is a series of waves with a long wavelength and period (time between crests) generated by a large, impulsive displacement of sea water. * Time between crests of the wave can vary from a few minutes to over an hour, but generally are in the range of 15 to 30 minutes. The most common cause of a tsunami is sea floor uplift associated with an earthquake. * Tsunamis are also triggered by landslides into or under the water surface, and can be generated by volcanic activity and meteorite impacts.
