Scientists have found mesosaurus fossils (a prehistoric reptile) on the each coast of South America and the west coast of South Africa. These
areas are now an ocean apart! Even though we know this animal could
swim, does the presence of mesosaurus fossils in two places support
Wegener's theory of continental drift? Explain your answer.

Explanation:

It does not support Wegener's theory of continental drift. Africa and South America were the part of a same land mass at one time, which then got separated into two different land forms called North America and South America and drifted to different locations other than the one from where they originated. This occurred due to continental drift. The evidence of this phenomena can be observed in fossils that were found to be same in both land forms. This depicts that same type of organisms were living in both land forms. Hence, gives the evidence that land forms were related.

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.
