These microorganisms are consumed by larger species—such as plankton—which, in their turn, are eaten by even larger animals, and so on. Therefore, information about the negative effects of water pollution should be not only studied, but spread among the general populous, taken into consideration, and prevented.
The ocean basins are in many ways similar to the land surface. Technically, the ocean essay should talk about it being a huge water-body is also home to rare species of plants and animals.
Relief of the Oceans 3. The Atlantic is the second largest ocean and many large rivers flow into the Atlantic carrying sediment from land. The blue-green color of water Plants and animals[ change change source ] Organisms that live in oceans can live in salt water.
See your grade before Free Expert Help Another problem connected to the contamination of water is the disruption of entire ecosystems.
Many regard the continental shelf as part of the continent submerged due to a rise in sea level, e. If aquatic life is disturbed then the colors of this nature may get stolen. Aquatic life is too complex.
These are the long, narrow trenches that plunge as great ocean deeps to a depth of 5, fathoms or 30, feet! They are not discovered yet or not specified or not named yet.
They are thus rich in plankton on which millions of surface and bottom-feeding fishes thrive. Its rate of accumulation is equally uncertain. We then see the reflected light as the color of water.
Fishing industries are very important because they make jobs and give food to millions of people. This aquatic life increases the beauty of this nature. Due to the free movement of ocean water, the proportions of different salts, remain remarkably constant in all oceans and even to great depths.
Variations are shown in salinity distribution maps by isohalines, lines joining places having an equal degree of salinity. Therefore it is said that aquatic life is very much different and opposite to a normal terrestrial life. This aquatic life increases the beauty of this nature. Relief of the Oceans: At the edge of the continental shelf, there is an abrupt change of gradient to about 1 in 20, forming the continental slope.
Few animals breathe through their gills while few breathe directly through their skins. This is expressed as salinity, the degree of saltiness of water, either as a percentage or more often in parts per thousand.
Color[ change change source ] Although many people believe that the oceans are blue because the water reflects the blue sky, this is actually not true. Deep sea core samples are obtained by boring for the study of the oceanic deposits—the various kinds of oozes, muds and clays.
There are submarine ridges, plateaux, canyons, plains and trenches. It was once thought to be featureless, but modern sounding devices reveal that the abyssal plain is far from being level. If aquatic life is so important then everyone must take good care of it.
Temperature of Ocean Water: The continental shelf is thus a shallow platform whose width varies greatly, from a few miles in the North Pacific off the continent of North America, to over miles off north-west Europe.
Small plant organisms that live near the surface and use sunlight to produce food are called phytoplankton. As warm water is lighter and rises, and cold water is denser and sinks, warm equatorial waters move slowly along the surface pole wards, while the heavier cold waters of the polar regions creep slowly along the bottom of the sea equator wards.
Amphibious animals are those who live on ground as well as inside water. With all these modem techniques at the disposal of the oceanographers, our knowledge of the mysteries of the oceans is greatly increased. This is expressed as salinity, the degree of saltiness of water, either as a percentage or more often in parts per thousand.
Discovery of the Oceans 2. These include many types of fishsuch as tuna, swordfish and marine mammals like dolphins and whales. These animals live completely different from normal living beings.An ocean is a large area of salt water between continents. Oceans are very big and they join smaller seas together.
Together, the oceans are like one "ocean", because all the "oceans" are joined. Oceans (or marine biomes) cover 72% of our planet. The largest ocean is the Pacific Ocean. Descriptive Essay on the Ocean essays When deprived of water, a sponge becomes hard and brittle.
It shrivels up like a wilted flower, lifeless. Water relaxes sponges, fills. An ocean is a large area of salt water between continents. Oceans are very big and they join smaller seas together.
Together, the oceans are like one "ocean", because all the "oceans" are joined. Oceans (or marine biomes) cover 72% of our planet.
The largest ocean is the Pacific Ocean. Research Papers words ( pages) The Birth of Fish; The Death of Oceans Essay - The Birth of Fish; The Death of Oceans Overview: Life and death are themselves opposites; then again in our oceans, life sometimes causes death.
The Ocean is a lot of water, which covers most of the earth. The oceans are located all around us, it’s broken into four sections, even though there are four sections the water is one continuous body of water.
The Indian Ocean is the third largest ocean, covering about 20% of the Earth’s water surface. The Arctic Ocean is the smallest ocean and it is located entirely in the North Polar Region. The largest sea is the South China Sea.Download
