Where would cold water flow in the ocean?
Where would cold water flow in the ocean?
Cold, salty water sinks to the bottom of the ocean. Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
What is the movement of cold water upward from the deep ocean?
Define upwelling: the movement of cold water upward from the deep ocean. Upwelling brings up tiny ocean organisms, minerals, and other materials from deeper layers of the water, increasing the supply of nutrients.
What is the movement of water in ocean called?
The horizontal and vertical motions are common in ocean water bodies. The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides. Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water.
How does the ocean water move?
Ocean water is constantly in motion: north-south, east-west, alongshore, and vertically. Seawater motions are the result of waves, tides, and currents (Figure below). Ocean movements are the consequence of many separate factors: wind, tides, Coriolis effect, water density differences, and the shape of the ocean basins.
Why is ocean water always moving?
These two factors, temperature and salinity, are the main driving forces behind Earth’s ocean conveyor belt, which is a huge water circulation system in the deep ocean that moves water around the globe.
How do you extract salt from ocean water?
There are two basic methods for breaking the bonds in saltwater: thermal distillation and membrane separation. Thermal distillation involves heat: Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down.
Which separation method could be used to separate water and salt from sea water?
distillation
What are 2 processes that remove salt to seawater?
The traditional process of desalination is distillation, i.e. boiling and re-condensation of seawater to leave salt and impurities behind. Currently there are two technologies with more desalination capacity in the world, multi-stage flash distillation and reverse osmosis.
What happens to salt after desalination?
When seawater is desalinated, the brine is returned to the sea. In addition, the brine is devoid of dissolved oxygen as a result of the desalination process. If it is released into calm water it can sink to the bottom as a plume of salty water that can kill organisms on the sea bed from a lack of oxygen.
Does all rivers flow to the ocean?
Rivers come in lots of different shapes and sizes, but they all have some things in common. All rivers and streams start at some high point. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake. …
