ALBUQUERQUE, N.M. - KOB meteorologist Eddie Garcia's a new You Asked 4 It question:
"Rainwater is fresh water, correct? This hurricane on the east coast gets its moisture from the ocean, then drops it as rain over land, if it picks up ocean water (salt water) but drops fresh water, where did the salt go," David asked.
Eddie Garcia explained, "rainwater is fresh water because of evaporation."
Whenever water evaporates from land or oceans, only the water molecule H2O returns to the atmosphere.
Salt, or its chemical name NaCl, and other impurities are left behind because they are not chemically bonded with water.
In the case of oceans, pure water evaporates and the salt stays behind.
