Solar Flares and Solar Phenomena

Explanation:

Solar Flares: Flares are largest explosive occurrence in our solar system.It is the region where heavy particles,protons,electrons are intensified.They are the bright areas of sun.Solar flares affects all layers of the sun.

Solar phenomena: It is naturally occurring within the outer atmosphere in the sun. Space weather disturbance can cause solar storms on earth, disconnecting communications and geomagnetic storms

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.
