As líquid water freezes, the molecules take up more space than aqua water what do you think would happen if frozen water molecules required less space than liquid water molecules? a) the density of ice would be greater than the density of liquid water and not float

The density of ice would be greater than the density of liquid water, and ice would not float.

wheres the other choices??

Explanation:

use smarts app it gives all theanswers

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.
