Brackish water is a mix of freshwater and saltwater, usually with a salinity between 0.5 and 30 parts per thousand. This type of water is often found in estuaries when rivers meet the ocean, or in areas where tides cause fluctuations in salinity levels.

Brackish water typically forms when fresh and salty water mix together, usually in areas close to the ocean such as estuaries. River outlets, swamps, marshes, and bays are also common sources of brackish water due to their proximity to the sea.

While some organisms can tolerate drinking brackish water, it's generally not considered safe for human consumption. The exact level of salinity makes a difference in how safe it is to drink - but unless you know exactly what you're dealing with, it's recommended that you avoid drinking brackish water.

Yes! Brackish water has practical uses since its higher concentration of salts helps prevent corrosion from happening within industrial pipes and other components during desalination processes. It can also be used to irrigate crops and create more fertile soil for vegetation growth, particularly in drier climates where fresh groundwater may be scarce.

Generally speaking, the salinity level of brackish waters range from 0.5 parts-per-thousand (ppt) up to around 30 ppt - but this can depend on location and other factors such as local tides or rainfall patterns that shift over time.

Yes - changes in humidity can affect the saltiness levels present in different types of bodies of waters including both freshwater and brackish sources. In particular, increased humidity levels can lower the salt content within brackish waters by diluting it slightly over time - although any change will likely be minimal compared to other environmental factors like tide cycles or local rainfall patterns.

Animals living within bodies of brackish waters have evolved very specific adaptations that allow them to survive these challenging environments - often relying on physiological mechanisms such as osmoregulation or metabolic shifts for survival in comparison with their freshwater counterparts which require less complexity for regulation purposes. Generally speaking most sea creatures thrive best along the coastline where salinity levels tend to be most consistent for them throughout year round cycles due to seasonal weather changes affecting local land based sources that influence their overall habitat dynamics.

Halophytes or "salt loving" plants are specially adapted species that enable them to thrive even under highly saline conditions and are generally ideal for planting near bodies of seawater or salty marshlands like estuaries and wetlands which contain higher concentrations of mineral salts than traditional freshwater ecosystems do naturally.
