Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Coral Reefs Coral Bleaching
977 wordsCoral Reefs are one of the worlds most beautiful habitats. They are often called the rainforests of the ocean, because they support such a diversity of life. They are massive underwater structures formed by the limestone skeletons of tiny invertebrate animals. These beautiful underwater structures are the largest and most diverse biological structures on earth, take thousands to years to form, yet they are being destroyed at an alarming rate. Coral Reefs are built by accumulated skeletons of tin...

Great Barrier Reef Calcium Carbonate
1,069 wordsIn order to understand what Diane Johnson meant in her story and what symbolism reef had I think it will be appropriate to examine in depth what is Great Barrier Reef, with which the main theme of the story was associated. Great Barrier Reef is undoubtedly a great symbol used for expression of protection, beauty and weakness at the same time. It is possible to see how this one symbol can incorporate so many different meanings through discovering wonder of nature Australian Great Barrier Reef. Th...

Million Years Ago Dry Land
722 wordsAbout four hundred and fifty million years ago, at the end of the Ordovician and in the beginning of the Silurian, the land was desolate and empty. Barren, hardly withered rock grounds, empty sand-, gravel- and clay plains, no green. Maybe some lichens. And at wet spots some algae with a couple of spider-like little creatures creeping around. In the neighbourhood of the mouth of rivers, where the water regularly flooded the land, it was probably green with algae. At such places, e. g. in Austral...

Coral Reefs And Algae
1,656 wordsCoral Reefs and Algae Coral reefs are unique ecological systems of the Earth Nature. These systems are very complicated and provide natural balance in the global ocean environment. Unfortunately, the human technological activity impacts coral reefs in the same harmful way as it impacts other ecological systems. Coral reefs are inhabited of approximately 25 % of marine species. They are very valuable because of their economic attractiveness through tourism and fisheries. A recent economic estimat...

Coral Bleaching Coral Reefs
1,512 wordsImagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimate's. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we will...

Coral Reefs Fringing Reefs
4,088 wordsCoral reefs are arguably the worlds most beautiful habitats. Coral reefs have been called the rainforests of the oceans, because of the rich diversity of life they support. Scientists have not yet finished counting the thousands of different species of plants and animals that use or live in the coral reef. There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. Fringing reefs are located close to shore, separated from land by only shallow water. Barrier reefs lie farther...

Crown Of Thorns Coral Reefs
3,746 wordsCoral reefs are among the most varied and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions from providing food and shelter to fish and invertebrates to protecting the shore from erosion. Unfortunately, as our understanding of corals and coral reefs increases, it becomes apparent that the effects of the human population on these communities may be increasing as well. Reef-building (or hermatypic) corals are of th...

Acid Rain Plant Growth
767 wordsPhosphates may be Untitled Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuabl...
