Apply: Where in the Gizmo (and in real life) do the following energy conversions occur? 26.
Chemical to thermal to electrical current:
27
Gravitational potential to kinetic to electrical
current:
28.
Electrical to sound, radiant and thermal energy
29.
Nuclear to thermal to electrical current

26. Coal is burned at a power plant

27. In dams.

28. Gas heater.

29. Nuclear power plant.

Explanation:

Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical  current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.

the answer would be..

b. sucking

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.
