What else can I help you with?
Which areas of the ocean have the lowest salinity and why?
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
Why doesnt the ocean freeze?
Many parts do freeze! However, it does require much lower temperatures to freeze ocean water than fresh water, mainly because the ocean is composed of salt water. Dissolving anything (including salt) in water lowers its freezing point and raises its boiling point.
What makes ocean water a solution?
Because there are thousands (for real) of things dissolved in it
List the reasons for variations in salinity in the various oceans?
Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.
Why would melting the Arctic ice cap not cause a rise in sea level on its own?
If you put an ice cube in a glass of water the water level will rise because the cube displaces the water. Now if you check the water level after the cube melts, it will be the same. So ocean levels will not change if floating chunks of ice melt. However, If the ice is on land and melts and the water runs into the ocean, that will increase the water level.
Most circulation of ocean water occurs because?
warmer, lighter equatorial. Cold sinking cold salty polar. Warm rising equatorial.
Circulation of ocean water occurs because?
its mainly because of tetronic platlets fond under the earth and the wind. some may occur due to heating up in one part and cooling up in other part
From what bodies of water do you think most evaporation occurs?
the ocean because its the largest water source on earth
What is the driving force of deep-ocean circulation?
The driving force of deep-ocean circulation is primarily the sinking of cold, dense water at high latitudes due to its higher density. This process is known as thermohaline circulation, where temperature and salinity differences create variations in water density, causing water masses to sink and drive the global ocean circulation.
Circulation of ocean water is called?
Current
Why does water runoff the surface of the earth?
This occurs because of gravity. Water runs from the highest places (mountains and plateaus, or where rainfall occurs) to the lowest point, into the ocean.
What is the circulation of water mostly responsible for?
Deep water ocean current
What is efficiently transported due to the circulation of the ocean water?
Heat.
Which masses from the Arctic Ocean are a significant part of the deep ocean circulation of?
The Arctic Ocean plays a crucial role in deep ocean circulation, particularly through the formation of dense water masses like Arctic Bottom Water (ABW) and Greenland Sea Deep Water. These cold, dense waters sink and contribute to the global thermohaline circulation, influencing the Atlantic Meridional Overturning Circulation. Additionally, the inflow of warmer, saltier water from the Atlantic, such as the North Atlantic Current, affects the overall dynamics of deep ocean circulation in the region.
When evaporation occurs how does that affect the salt in the ocean?
Not at all because when the water evaporates the salt remains unchanged
How does downwelling drive thermohaline circulation?
Downwelling is a crucial process in thermohaline circulation, as it occurs when dense, cold, and salty water sinks into the ocean depths, particularly in polar regions. This sinking water drives the global conveyor belt of ocean currents, facilitating the transport of heat and nutrients across the world's oceans. As downwelling occurs, it helps regulate climate by redistributing warm and cold water, influencing weather patterns and marine ecosystems. Ultimately, downwelling is a key mechanism that maintains the balance of oceanic circulation and global climate systems.
What is a possible cause that the Atlantic Ocean water is slightly less dense than the average water of any other ocean?
Thermohaline circulation is the process of cold water at the poles creeping along the ocean floor. It meets with north and south polar water creates a dawdling subsurface circulation.
