Water Variations by Leland Yonkers
Fresh Water, Salt Water, Brackish Water
Fresh Water is natural water found on earth in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and, streams. Low concentration of salt and other dissolved solids. It is an important resource that is replenished through the water cycle.
Salt water is water from the sea or ocean. has a high concentration of salts and supports ocean life. Freshwater creatures cannot thrive in salt water due to the differing chemistry of seawater.
Brackish water is in between salt water and fresh water on the level of concentration. It is often formed when salt water is mixed with freshwater in areas such as marshes etc. It is not often naturally formed, and is sometimes created by dikes and other manmade structures.
