Freshwater and Saltwater Systems - Topics 1-2 Flashcards
Evaporation
converts liquid water from Earth’s surface into gaseous water vapor
How do rainbows form?
When light is fractured into the colour spectrum through water particles in the air. Most often happens after rain.
How much of the planets water is trapped in ice bergs?

Water quality
The characteristics of a water resource that make it suitable or unsuitable for various uses
