Question

A student who grew up in a tropical country and is studying in the United States may have no experience with static electricity sparks and shocks until their first American winter. Explain.

Answer 1

Step-by-step explanation:

Water in the air (humidity) helps to dissipate static charge that builds up. If the air is very dry, the charge can't dissipate, so it builds up until there is enough to spark.

Tropical countries are typically more humid than the United States, but I guess that depends on where you are in the US.
