1. What is the scientific name?Global distillation (also known as the Grasshopper Effect)
2. What is the primary transported substances?Persistent Organic Pollutants (POPs), sulfur oxides (SOx), and heavy metals
3. Why do pollutants travel from warm places to cold places?Warm air makes the chemicals evaporate, and cold air makes them condense. The temperature difference pulls the chemicals from hot areas to cold ones, like a giant invisible conveyor belt.
4. How does the Grasshopper Effect get its name?It is called the Grasshopper Effect because the chemicals hop from one place to another, just like a grasshopper jumps across the ground.

Geochemical Process: A natural process involving chemical changes and the Earth's crust and atmosphere.
Volatile Chemicals: Substances that readily evaporate or turn into gas at relatively low temperatures.
Biomagnification: The increasing concentration of a substance, such as a toxic chemical, in organisms at successively higher levels in a food chain.
