Question: Process:  -He air we breathe contains oxygen and other gases -Once in the lungs, oxygen is moved into the bloodstream and carried through your body -At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide -Your bloodstream then carries this waste gas back to the lungs where it is removed from the blood stream and then exhaled -Your lungs and respiratory system automatically perform this vital process, called gas exchange -
 Question: What is the effect of more polluted waterways on a greater amount of oxygen being delivered to the blood stream.?

Answer: none


Question: Process:  -Wind and water erode rocks -The wind and water pick up sediment that came off the rocks -Sediment is carried to an area by the wind, water, air, or ice -Sediment is deposited on the same spot many times -The sediment piles on top of other sediment for a long time -The sediment near the bottom is compressed by the weight of newer sediment -The sediment becomes sedimentary rock as it is pushed together by the heavy weight -
 Question: What is the effect of the air pressure drops on more sediment is deposited.?

Answer: against


Question: Process:  -Sediment settles in a place due to gravity -The sediment breaks down into small particles -Wind or water picks up the sediment -The sediment travels along the same route as the wind or water -The sediment is deposited at new locations by the wind or water -The sediment is picked up again by new wind or water -The sediment travels further -The sediment is deposited again in a new place.
 Question: What is the effect of there is less public awareness on less breakdown into sediment.?

Answer:
none
