Oceanography also called oceanology or marine science , is the branch of Earth science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. What is oceanography?

Tsunami & its occurrence Tsunamis occur most frequently in the Pacific, particularly along the "Pacific Ring of Fire". This zone is found at the northern edge of the Pacific Plate and refers to the geologically most active fields of the earth. Several times a year, strong earthquakes of at least 7 on the Richter scale result in tsunamis. Japan, for example, is hit by a tsunami at least once a year. Due to its geographical situation, it is also the country where the most casualties have been claimed in the last thousand years. In this period, more than 160 000 people have been the victims of tsunamis. As a result, Japan has developed an effective tsunami warning system and many Japanese villages and cities protect themselves by means of gigantic dykes. Other states in the tsunami danger zones are, however, not as well equipped as Japan. Tsunamis occur most frequently in the Pacific, particularly along the "Pacific Ring of Fire".

Hurricane basics & conditions > Hurricanes originate in the tropics for one main reason – the perfect weather conditions. The two prerequisites for a hurricane are warm water and moist warm air. It all begins when rays from the sun heat the water surface to at least 80ºF (26.5ºC). This warms the air at the ocean surface which rises up, taking water in the form of vapour with it. > This warm moist air encounters cooler air above, and the water vapour condenses out and not only forms storm clouds and rain drops, but it releases latent heat energy which further warms
