As you have learned, there are a lot of career options in marine science. Choose one and do some online research to determine: what a person with that job actually does all day the education required for that position the starting salary range the skills needed (such as technological skills) When you have gathered that information, create a poster designed to educate people about that position and attract them to the profession. Your poster should be visually appealing while providing the required information as well as any other details you learn in your research that would make the profession attractive to students. You can either make the poster on your computer or make a physical poster and take a picture of it. If you make a physical poster and photograph it, make sure that all the details are clear and include close-up shots as needed.

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.
