What best describes the change in salinity in an estuary at low tide?
Salinity falls as the out flowing tide brings in more fresh river water.
What causes the amount of salt in the water of an esturay to change?
The amount of salt in the water of an estuary can change due to various factors. One major factor is the mixing of freshwater from rivers with saltwater from the ocean, which can dilute or increase the salt concentration. Seasonal variations in rainfall and temperature can also affect the amount of salt in the water. Additionally, human activities such as agriculture, industry, and pollution can introduce or remove salt from the estuary, causing changes in its salinity.
What are the physical factors of an estuary?
Physical factors of an estuary include salinity levels, temperature variations, turbidity (clarity of water), tidal currents, and substrate composition (the type of material on the estuary floor). These factors greatly influence the ecosystem and species that inhabit the estuary.
What is one factor that decreases salinity in seawater?
Salinity in oceans decrease when near a river because the river adds fresh water, which lowers the percentage of salt in the water, causing the salinity to decrease.
A coastal inlet or bay where fresh water mixes with salt water?
Estuary is a coastal inlet or bay where the tide meets a river current, resulting in brackish water mixing salt water and fresh water. This unique ecosystem supports diverse marine and plant life due to the varying salinity levels.

Salinity falls as the out flowing tide brings in more fresh river water.
Would salinity increase or decrease in an estuary during spring floods?
Salinity would decrease in an estuary during spring floods due to the influx of freshwater from increased runoff and precipitation. The dilution effect of the additional freshwater entering the estuary would lower the overall salinity levels.

What is the average salinity in an estuary?
The average salinity in an estuary typically ranges from 0.5 to 35 parts per thousand (ppt). Salinity levels can vary based on factors such as proximity to the ocean, freshwater input, and tidal influences.
How would salinity change if some ocean water evaporated?
Salinity is increased.
What is one factor that decreases salinity in seawater?
Salinity in oceans decrease when near a river because the river adds fresh water, which lowers the percentage of salt in the water, causing the salinity to decrease.
A pycnocline caused by salinity differences is called?
A halocline is a pycnocline caused by salinity differences in water. It is a distinct layer where there is a rapid change in salinity with depth, leading to a change in water density within a body of water.
What are some abiotic and biotic factors for the Estuary Biome?
Abiotic factors in the Estuary biome include water salinity, temperature, and dissolved oxygen levels. Biotic factors include phytoplankton, aquatic plants, fish, and birds that thrive in the brackish water environment.
Is Observing the change in salinity of water over time independent or dependent?
Observing the change in salinity of water over time can be independent or dependent. This depends on the experiment.
How does salinity change in warm climates where water evaporates quickly?
Salinity is increased during time.
A coastal inlet or bay where fresh water mixes with salt water?
Estuary is a coastal inlet or bay where the tide meets a river current, resulting in brackish water mixing salt water and fresh water. This unique ecosystem supports diverse marine and plant life due to the varying salinity levels.
