brackish salty water slightly freshwater land tides salinity more salty not as salty attach surfaces

Explanation:

Estuaries are ecosystems where freshwater empties into the ocean. They have brackish water, which means slightly salty, or water not as salty than freshwater but not as salty as ocean water.
Intertidal zones are the areas where the ocean meets the land between high and low tides. Animals and plants must be adapted to tolerate salinity changes, varying levels of water, and must be able to attach themselves to surfaces so they are not harmed by the force of waves.
