Problem: Process: - Chemicals like sulfur dioxide and nitrogen are released into the air - These substances rise into the high atmosphere - They react with water and oxygen - This creates a more acidic rain - The rain with the high acid content falls. Question: suppose there will be less water in the streams happens, how will it affect LESS damage by acid rain. - A: more - B: less - C: no effect

A: C

Problem: Process: - The liver filters blood from the digestive tract - The liver produces bile - The liver produces proteins for blood plasma - The liver converts excess glucose into glycogen for storage - The liver converts ammonia to urea - The liver regulates blood clotting. Question: suppose blood is pumped to liver happens, how will it affect "the liver isnt healthy". - A: more - B: less - C: no effect

A: B

Problem: Process: - Gases cause pressure beneath the earth - The gases come to a head and push molten magma to the surface - The magma cools - With enough time the pressure builds up greatly - The resulting volcano may explode. Question: suppose more light to travel happens, how will it affect MORE or GREATER eruptions. - A: more - B: less - C: no effect

A: C

Problem: Process: - Water comes into contact with something made of iron - The water combines with carbon dioxide in the air to form carbonic acid - As the acid is formed, the iron starts to dissolve - Some of the water breaks down into hydrogen and oxygen - The free oxygen and dissolved iron bond together - They form iron oxide, which is rust - Question: suppose carbonic acid does not form happens, how will it affect the water will release free oxygen. - A: more - B: less - C: no effect

A:
B
