The Quiz: What is brackish water?
A A mix of salt and fresh water
B Water that is at least 80 degrees F
C Water cloudy with sediment
Brackish water is a mix of salt and fresh water and is usually found where rivers meet the sea, like here in Senegal, where the Saloum River flows into the Atlantic. Not as salty as seawater, brackish water supports its own unique ecosystem. Most plants can’t survive in brackish water, but mangroves thrive in this saline environment because their roots filter out the salt. Certain species of fish, crustaceans, and amphibians tend to flourish in brackish waters.
The correct answer to this quiz is A mix of salt and fresh water.
