Formed from silt deposited by rivers that empty into the ocean?
Delta is a landform formed from silt deposited by rivers that empty into a body of water, typically an ocean. The sediment builds up over time, creating a fan-shaped or triangular landmass where the river meets the larger body of water. Deltas are important habitats for wildlife and can also provide fertile land for agriculture.
What is one advantage of rivers overflowing?
nutrients in the water can be deposited
Why doesn't ocean water ever get diluted by fresh water rivers running into the oceans?
Ocean water is diluted by the rivers. Probably the best example of this is where the Amazon river meets the ocean. Approximately 160km away from the mouth of the river Amazon, the ocean water is still fresh enough to drink. It probably doesn't taste very nice though. IN ADDITION: Volume. The amount of fresh water that flows into the ocean can be measured in parts per million. It doesn't have the volume needed to change the salinity of the ocean as a whole. It would be equivalent to adding one drop of food coloring to a swimming pool and trying to notice the difference later. +++ Such dilution is local, but the ocean's salinity is by no means homogenous anyway. The water circulation is cyclic, with vapour from the sea being distilled water. Once it falls as rain or snow, it collects minerals from the rocks the rivers are eroding, helping maintain the sea's overall cocktail of dissolved salts. So the rivers have no real effect on the sea's saltiness overall, but if anything maintain it.
Why the water of the ocean is salty?
When water goes to the ocean, most of the time its by a river. When rivers travel over land it picks up particles like salt. When the river meets the ocean at the rivers delta the slowing of the speed of the river causes the bigger sized particles to get deposited at the bottom of the ocean. The smaller particles(salt) remain in the water making the water salty.
Most river sediments are deposited?
They are deposited at the river mouth, before it finally empties its water into the ocean.
Where did the water of the ocean come from?
the main source for the ocean water is the rain and spring water and water coming and adding from the rivers
How are oceans and rivers alike and how are they different?
Rivers form at high ground where water vapor becomes cold and condenses into rain. Rivers almost always feed into the Ocean eventually. River water is generally high in nutrients, good for irrigation and farming, drinkable, and contains about 1 part per thousand salt content. Ocean water is undrinkable. It is an extremely expensive process to desalinate ocean water for mass consumption. Ocean water contains a much higher salt content, because rivers have deposited salt into the oceans for millions of years. Ocean water contains about 35 parts per thousand. Also Oceans differ from rivers in that they support the thermohaline cycle, which transfers heat from the equator to colder regions of the world.J.P. -lord geographer
Where is silt and soil deposited?
Silt and soil are typically deposited in areas near water sources such as rivers, streams, and lakes. They settle in these areas due to the action of water carrying and depositing sediment as it flows. This process is known as sedimentation.
What winds up carrying water to the ocean?
Rivers
How do rivers affect the ocean?
They add more water to the ocean.
What would happen if river water where to flow into the ocean?
River water DOES flow into the ocean. Although some rivers flow into lakes, all those lakes have rivers flowing out of them that eventually end up in the ocean (except for a few inland bodies of salt water such as the Dead Sea and the Great Salt Lake).
What is soil deposited by water kwown as?
Soil deposited by water is known as alluvium. This type of soil is typically made up of silt, clay, sand, and gravel deposits that have been carried and deposited by streams, rivers, and other bodies of water.
