Yes. All rivers are fresh water, but those that have Estuaries are then changed from Fresh to Tidal where the Sea has influence, but this is only restricted to the part of the estuary that is tidal. In rivers that are affected by modern Industries, Fresh may not be the appearance of the water, due to Pollution, which I suspect the Question alludes to, but the water, if it isn't salty, is essentially described as 'Fresh'.
For the most part, yes. The closer to the ocean, the saltier it gets. Around the Delaware Memorial Bridge is where it becomes mostly fresh.
Hudson Bay is in fact both. Taking into account the inflow of salt water that flows in from the Arctic Ocean (Fax Basin) and fresh water from the rivers that pour into James Bay/ Hudson Bay the ratio of fresh water to salt water is 2:5. Taking into account the fresh water that comes from the thawing of the ice cover on James Bay/Hudson Bay the ratio is 4:5.
It is salt water, because it is a continuation of the ocean water.
yes and no because it is the only one that has both salt and fresh water
Hudson bay is salt water.
Cape Cod Bay in Massachusetts is a salt water bay that borders the Atlantic Ocean. On the east shore of this bay is the historic Plymouth Rock.
Nova Scotia is the province in Canada that has borders on both fresh water (Atlantic Ocean) and salt water (Bay of Fundy).
A bay is a body of water bordered on 3 sides by land, and by definition the "4th side" is the ocean. Whether it is saltwater or freshwater will depend on where the water is from. If the bay is of an ocean, it will be of saltwater. If it is of a freshwater lake or river, it will be of freshwater.
Baffin Bay is a body of saltwater located in the North Atlantic Ocean, between Greenland and Canada.
A coastal inlet or bay where fresh water mixes with salt water is called an estuary. Estuaries are important ecosystems that support a diverse array of plant and animal species due to the mix of freshwater and saltwater conditions.
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.
A sea is a large body of salt water, sometimes a part of an ocean, which may be partially or completely enclosed by land. A bay is an indentation of the shoreline of a larger body of salt or fresh water.
Brackish they live in brackish Brackish water is a mixture of salt a fresh water like for example the....... Chesapeake bay
