a piece of expository writing about coral reefs. I taught it fitting to write on coral reefs because they are so important and are getting destroyed every day. Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Living coral reefs are the foundation for many marine species

Topic: “Describe the way in which coral reefs have contributed to social and cultural life in the Caribbean.” Corals are marine animals which usually live in compact colonies of many identical polyps. Corals secrete calcium carbonate which forms reefs. Such reefs and are located near the Equator in tropical and subtropical waters. The largest coral reef is the Great Barrier Reef located off the coast of Queensland‚ Australia. Coral reefs are often referred to as the “rainforests of the ocean”

Coral reefs have existed on this planet for approximately 450 million years. They provide an extremely diverse marine ecosystem. (Bellwood and Wainwirght2002) Coral reefs are the largest natural structures in the world and occur in over 100 countries. They are the result of a remarkable relationship between coral animals and microscopic algae. The microscopic algae (zooxanthellae) coverts sunlight and carbon dioxide into oxygen (photosynthesis) and carbohydrates for the coral animals (polyps)

today are 30 percent more acidic than they were at the time of the Industrial Revolution. This interferes with the way that corals produce calcium carbonate‚ and it becomes difficult to build reefs. Oil spills are a major issue‚ and in recent accidents; ships hit coral reefs off India and spilt oil‚ causing reef damage. Surface currents are more rapid than the currents of the deep sea‚ limiting the ability of the deeper plumes (oil) to spread widely; oil and chemicals will diffuse as they migrate

The raw data provided by Riegl and Purkis’s study is what will make others wary of what is happening to coral reefs and furthermore encourage them to gain a deeper understanding of why we need these marine dwellings and providers. The reader of their study will find himself or herself internally pondering: “If we don’t have these coral reefs‚ how will humankind be impacted?” The data obtained from Riegl and Purkis in this study also help us to pinpoint what our best option

Final Piece Outline Stefano Phillips Topic: Ecosystem Focused topic: Decline of Coral Reefs Thesis Statement: Caribbean waters which contains coral reefs‚ one of the world’s most stunning‚ interesting and dynamic ecosystems‚ is diminishing rapidly due to pollution‚ overfishing and climate change. I. Pollution has greatly led to the decline in coral reefs. * Sources of pollution to coral reefs. 1. Land based pollution that runs into the sea is a major threat to coral reefs. 2.

In today’s society‚ thousands of artificial reefs are manufactured every year throughout the United States using an integration of private‚ federal‚ state and local government funds. Not only are artificial reefs suggested to preserve marine populations‚ but they are also considered to be “economically viable” (‘How artificial reefs are economically viable’). The role of artificial reefs is to attract marine life‚ which brings in approximately $300‚000 a year for many marine wildlife service programs

The park itself covers nearly 800 square miles. There is not an area of the same size that can match the diversity of plants and animals. There are nearly 18‚000 species that have been found in the parks area. Scientists believe that there is an additional 20‚000 to 80‚000 species that possibly live in the area. They believe that there is so much diversity because of the mountains‚ glaciers and the weather of the area. There are close to 100 species of trees that grow in the area. That’s more than
