Oceanography

The sea is the most straightforward feature of the earths surface. Approximately seventy percent of this surface is cover by water, in oneness way or another. under this water be the long-familiar sands of the beaches, bottoms of bays, and the inshore ocean. farther offshore this water covers an awed submarine topography of underwater canyons, trenches, mountains, and plains. opposed the continents, which argon physically scattered from one another, the oceans are perpetual and interconnected. Since the world ocean is continuous(M.J. Keen) it has comparable characteristics throughout. In the early 1870s oceanographers collected seawater samples from all of the seas of the world at a variety of depths. When analyzed, the samples were ensnare to have quite like characteristics. These findings convinced many that a method of check was needed. The reputation of oceans was named oceanography.         Density, table salt, and temperature are rattling important concepts in the admit of oceanography. The saltiness and temperature of the water bow its density, and the differences in density are the major factor in understanding the constituteation of currents and the positions of water git in the sea. In addition, temperature and salinity play major roles in influencing the distribution of plants and animals.         The depositorys of the sea appal may be careen integrity into lithogenous, hydrogenous, biogenous, and cosmogenous sediments.

Lithogenous sediments are the major sediments on the ocean floor. They are derived from the chemical substance substance and robotlike weathering of rocks. Biogenous sediments are make up primarily of the cautionary outter cover of small marine animals and plants. If these ashes comprise at least(prenominal) thirty percent of the sediment it is called an ooze. Oozes were named for the types of organisms that formed them. Hydrogenous sediments form as a import of the chemical reactions that occur in the seawater. These reactions result in the...
