What best describes the change in salinity in an estuary at high tide (as water enters the area)?
At high tide, salinity in an estuary typically decreases as freshwater from rivers and streams flows into the area, diluting the saltwater from the ocean. This influx of freshwater can create a stratification effect, where less dense freshwater overlays the denser saltwater. Consequently, the overall salinity levels within the estuary are lower during high tide compared to low tide when more saltwater is dominant.

How does the change in salinity in an estuary at high tide as water enters the area?
At high tide, as seawater enters an estuary, the salinity typically increases due to the influx of saltwater. This process can lead to a stratification of water layers, where the denser, saltier water sinks below the lighter, freshwater layer. The change in salinity can influence the local ecosystem, affecting the distribution and behavior of aquatic organisms that are adapted to specific salinity levels. Additionally, this fluctuation can impact nutrient cycling and overall water quality in 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.
When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.
What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
A substance that enters into and is altered through a chemical change?
These substances are called reactants.

Why does the salinity change at the point where a river enters the ocean?
Because the ocean is saltwater
The River Niles estuary?
No gradually widening estuary as on the Thames or the St lawrence. The Nile enters the Mediterranean via a delta. You would do well to look it up on a map.
What are three areas in the ocean where salinity may be less than average?
Where a major river enters. Where a large glacier enters. Where an ice shelf is melting. Upon reflection, about one half of the ocean will have a salinity less than the average.
What do you call the place where a river runs into the sea?
The river reaches the sea in its Estuary.
Which term describes the bending of a wave as it travels into a different medium?
Refraction describes the bending of a wave as it travels into a different medium, due to the change in speed of the wave as it enters the new medium.
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.
Where does the Shannon river end?
After passing through Limerick city, it flows into the Shannon Estuary where it meets the sea. The Shannon Estuary runs between north Limerick and north Kerry on the southside and south Clare on the northside. It then enters the Atlantic Ocean.
What is the area where a freshwater river or stream enters the ocean?
The area where a freshwater river or stream enters the ocean is called an estuary. It is a coastal area of brackish water formed when freshwater enters the ocean.
What is the point where a river enters a lake or sea?
Answer 1The point at which a waterway [creek, river, etc.] enters another body of water [stream, lake, sea, ocean, etc.] is called the "river mouth."
Where does the river severn enter the sea?
It finishes at the Severn estuary which then feeds into the Bristol channel
What term describes a streak of light when a meteoroid enters earths atmosphere?
"Meteor" does.
