biome makes up the largest part of the biosphere‚ covering nearly 75% of the Earth’s surface and consists of the freshwater biome and the marine biome. Freshwater regions consist of ponds‚ lakes‚ streams‚ rivers‚ wetlands and marine regions include oceans‚ coral reefs and estuaries. Marine biomes generally have salt concentrations that average 3%‚ whereas freshwater biomes are usually characterised by a salt concentration of less than 0.1%. The aquatic biome is probably the most important of all the

It helps keep garbage such as glass‚ plastic and metal out of our oceans. • Not only should you recycle‚ but buy products that are recycled. By purchasing these products‚ you are helping to conserve natural resources‚ and to protect the environment. Our oceans provide the earth with most of our oxygen‚ moisture‚ and weather patterns.

I was a little girl I loved the ocean and I wanted to be a marine biologist so I could work closely with those beautiful animals. The artworks I tend to be attracted to are that of dolphins and whales and of oceanic scenery. To look at the photograph of the humpback whale‚ captured in his natural habitat‚ it looks like a peaceful and serene atmosphere. The whale was beautifully captured in action during his swim. I feel the light that is shining through the ocean surface is illuminating the whale

Although we do not know exactly how much Bluefin tuna are left in the ocean‚ we estimate the amount we caught. Some experts said‚ "The Atlantic Bluefin population has declined up to 85 percent from its original numbers" (Richardon). Some fishermen find and catch Bluefin because of their profits even thought some Bluefin do

The professor‚ however‚ believes that none of these theories could justify the real source of these noises. The professor’s reasons to refute these theories are as follows. First‚ the author suggests that the Orca whales which live in the ocean might make special noises to attract mates. Although the professors says this could be possible in the

pertaining to “Intergovernmental Relations and Ocean Policy Change: 1971-85”‚ there are several aspects that should be considered. One of the most essential as well as important aspects involves understanding the affects that policy changes have toward society. In my opinion‚ this case study is an appropriate example of how the concerns within political transmit inactivity or change because of corporate and profit growth.

The water resource problem in this video is the overfishing of the ocean. Overfishing of the ocean has shifted the entire ecosystem. The ocean today has far less fish life than it used to. One estimate shows only one-tenth of the sharks‚ tuna‚ cod and other large predatory fish swim in the ocean. around the world. The loss of fish continues. Overfishing occurs when fish and other marine species are caught at a faster rate then they can reproduce. There is a high demand for fish. The

Q.2 (from Street‚ Watters‚ and Vennard) The weight density γ = ρg of water in the ocean may be calculated from the empirical relation γ = γo + K(h1/2)‚ in which h is the depth below the ocean surface‚ K a constant‚ and γo weight density at the ocean surface. Derive an expression for the pressure at any depth h in terms of γo‚ h and K. Calculate the weight density and pressure at a depth of 3.22 km‚ assuming γo =
