How do conditions change as the depth of the ocean water increases

a) temperature increases and pressure increases

b) temperature decreases and pressure increases

c) temperature increases and pressure decreases

d) temperature decreases and pressure decreases

B) Temperature decrease and pressure increases

option b

Explanation: As we move down in the ocean water, the temperature of the water decreases as the water does not receives the sunlight in depth. The sunlight reaches upto a certain depth besides that the water is cool.

The pressure increases as we move down and this is the reason the marine animals that are found in depth are flattened.

So, the pressure increases and the temperature decreases in the depth of ocean.

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.
