The Grand Coulee dam and hydroelectric plant are located on the Columbia River in Washington state. How does this hydroelectric power plant affect the natural resources in the state over a long period of time
O A. Coal and gas are less likely to be burned to generate electricity.
B. Water quality is improved when the dam filters the river system.
C. Soil resources are conserved when reservoirs are filled behind the dam.
O D. Air quality decreases when electricity is generated through hydroelectric power.

Explanation: Hydropower is the generation of electricity from water through the construction of dams. it is a renewable energy source use over a wide range of environment. Construction of a waters storage project can raise the water level behind a dam from a few feet to several hundred feet by prevention water free flow called Inundation.

It leads to migration of human and other living organism such as fish and salmon. Salmon movement may be disoriented through the slower move of the water this leads to migration.

Fish moving around the dam coming in contact with turbines and the walls of the dam can become stressed, injured or die

vegetation and surrounding water it provide habitat for birds, waterfowl, and small and large mammals when hydroelectric project results in blockage of free-flowing river, the nesting, forage, and cover provided for the organism in these areas is temporarily or permanently lost.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
