This map shows the pH levels in rain throughout the United States. We would expect to see the MOST damage to evergreen trees in which area of the United States?
A) midwest
B) northeast
C) west coast
D) deep south

B/ Northeast

Explanation: The areas on the map in dark blue have a pH level of 5.5, the highest shown on the map. Acid rain lowers the pH level. Therefore, the area with the lowest pH and extensive evergreen tree growth would be the northeast United States. In this mountainous area, the predominant tree species are evergreens like spruce and pine. Acid rain effects their survival, causing needles to turn yellow, fall off, and eventually, the trees can die.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.
