The grasshopper effect occurs when air pollutants are transported from tropical and temperate areas to the earth's polar regions by evaporation and wind.

Question

Quizplus · Accepted Answer

The grasshopper effect is a real phenomenon in atmospheric science where persistent organic pollutants (POPs) are transported to regions thousands of miles away from their source by evaporation and wind. This is due to the fact that POPs are relatively volatile and non-polar compounds that can be transported long distances in the atmosphere without being removed by rain or other processes. The term "grasshopper effect" was coined because grasshoppers and other migratory insects were observed to be carrying POPs to high latitudes in the Arctic and Antarctic regions.
