📚 What is Fresh Water?
Fresh water is naturally occurring water that has a low concentration of dissolved salts and other total dissolved solids. Think of the water you find in lakes, rivers, and streams! It's what we need to drink and grow our food.
🌊 What is Salt Water?
Salt water, on the other hand, contains a high concentration of dissolved salts, mostly sodium chloride (that's table salt!). The ocean is the biggest example of salt water. Salt water isn't safe for us to drink directly, and most plants can't grow in it.
