You have probably heard about many of the major natural features in the United States, such as the Appalachian Mountains or the Grand Canyon, but what about the ocean? In this assignment, you will be using the Internet to research and discover some of the distinctive features on the ocean floor of any ocean or sea. At least 5 features should be chosen. Create a slideshow using the presentation software of your choice to address each of the following points for the features that you chose: Location of the feature
Description of the feature
Image of the feature
The role of plate tectonics in the development of this feature
Your slides should be free of mechanical errors, well organized, and easy to read. The presentation should contain no more than 20 slides. The last slide should list the websites where you found your information.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
