Process: - Acid rain flows through soil - Chemicals from the acid rain kill plants and trees - The acid rainwater flows into rivers and streams - The chemicals kill fish - The chemicals kill animals that drink the water - Nitrogen builds up - Nitrogen destroys fish and shellfish populations. Question: suppose Less chemicals soaked in the soil happens, how will it affect LESS damage by acid rain. - A: more - B: less - C: no effect
Ans: A

Process: - The gravity of the sun pulls its mass inward - There is a lot of pressure on the Sun - The pressure forces atoms of hydrogen to fuse together in nuclear reactions - The energy from the reactions gives off different kinds of light - The light travels to the Earth. Question: suppose there will be less energy from the sun happens, how will it affect MORE sunlight arriving at the Earth. - A: more - B: less - C: no effect
Ans: B

Process: - Thunderstorms form over the ocean - An area of low pressure causes rotation - Several thunderstorms come together around this area - The storm is fed by rising air from warm ocean water evaporating - When the wind speeds reach 74 mph the storm is considered a hurricane. Question: suppose there is an El Nino occuring happens, how will it affect wind speed will build less quickly. - A: more - B: less - C: no effect
Ans: B

Process: - You breathe oxygen into your body through the nose or mouth - The oxygen travels to the lungs through the windpipe - The air sacs in the lungs send the oxygen into the blood stream - The carbon dioxide in the blood stream is transferred to the air sacs - The lungs expel through the nose or mouth back into the environment. Question: suppose The person may breathe more rapidly happens, how will it affect a GREATER amount of oxygen being delivered to the blood stream. - A: more - B: less - C: no effect
Ans: A
