Oceanography Ch. 4, 5 & 6 Why does the ocean not boil or freeze solid in different regions of the world? Heat is transported by oceanic and atmospheric circulation The pycnocline isolates the majority of the world ocean from heating and cooling brought on by solar energy fluctuations What is the main reason for the stratification in the north polar waters?

Dispatch from the Deep: Global Ocean Circulation and Deep Sea Temperatures No matter how warm the surface of the ocean gets, the ocean's huge volume and deep basins keep temperatures at the bottom of the ocean at only slightly above freezing. At the abyssal zone, the part of the sea closest to the vents, it's way too cold to even dip a pinky into the water.

If the polar ice caps melted, how much would the oceans rise? But there might be a less dramatic reason than polar ice melting for the higher ocean level -- the higher temperature of the water. Water is most dense at 4 degrees Celsius. Above and below this temperature, the density of water decreases (the same weight of water occupies a bigger space).

Introduction Sea ice is simply frozen ocean water. It forms, grows, and melts in the ocean. In contrast, icebergs, glaciers, ice sheets, and ice shelves all originate on land. Sea ice occurs in both the Arctic and Antarctic.

How Did the Oceans Get Salty? Since oceans are closed systems (water flows in but hardly flows out) when water evaporates it leaves the salts behind and more stream and rivers flows bring in more water and part of these also evaporates and so on creating a cycle (part of the hydrologic cycle)of salt accumulation which is what is seen today.

Can the ocean freeze? Ocean water freezes at a lower temperature than freshwater. At least 15 percent of the ocean is covered by sea ice some part of the year. Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit, because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.

Warm water expands? Well if it didn't expand when it was frozen then its density would not decrease. I'm sure everyone is familiar with ice cubes that are less dense then water floating on the surface. If ice did not do not then there would be an awful positive feedback loop that would freeze more of the world's ocean waters. The frozen water on hte surface is able to be heated by the sun's radiation, but if were not able to float it would sink to the bottom. quasi426, Apr 13, 2006 Jan 28, 2007 #9

Why do coastal areas have milder climates than adjacent inland areas?? Because of this, the warm ocean will warm the cold air and the cool ocean will cool the warm air nearby. In the middle of a continent, you have no energy buffer as great as the ocean so the air temperature can get hotter and colder much more rapidly. Source(s): http://en.wikipedia.org/wiki/Heat_capaci...est Answer: Water has a higher heat capacity than air which means for a same amount of each it takes more energy for water to change temperature than air.

Why Doesn't the Ocean Freeze? In many parts of the world, winter temperatures drop low enough to make rivers and lakes freeze. And in those same parts of the world, where even those waters freeze, the ocean waters will not. Think about the pictures you’ve seen of the Arctic region. Most of the earth’s Arctic region is a frozen tundra, except the ocean. Why?

Scientists Warn of Rising Oceans From Polar Melt Scientists Warn of Rising Oceans From Polar Melt. A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday. If the findings hold up, they suggest that the melting could destabilize neighboring parts of the ice sheet and a rise in sea level of 10 feet or more may be unavoidable in coming centuries.

Water that water has an anomalously high melting and boiling point; that solid water or ice is less dense than liquid; and that water has a high surface tension. Melting and Boiling Point of Water Phase changes in matter result because of a change in the translational motion of molecules. A solid is a solid because its molecules are stuck in place.

At what temperature does sea water boil and freeze? - sea water does not have the same salt content everywhere, for example : the Mediterranean contains more salt (per liter) than the Atlantic; the English channel contains slightly less (because of the rivers that empty into it)

- Photo courtesy of the NOAA Corps Library. Why is Antarctica colder than the Arctic? The main reason why Antarctica is colder than the Arctic is that Antarctica is a continent surrounded by an ocean while the Arctic is an ocean almost completely surrounded by continents and Greenland. The Arctic's ice is relatively thin compared with Antarctica and it has water, not land, under it.

Where is the salinity of the ocean when its levels are high? Is it at the equator, the north pole or at the tropic? Temperature and density of ocean water are related inversely: warm water means low density, cold water means denser seawater. The salt content of the water also affects Ocean density. Sea Surface Salinity: Sea water is about a 3.49% salt solution, the rest is freshwater. The more saline, the denser the seawater. As the range of salt concentration in the ocean varies from about 3.2 to 3.8%, oceanographers refer to salt content as 'salinity', express salt concentration as parts per thousand; 34.9 ppt is the average salinity.

Does water freeze or boil in space? But when you put liquid water in space — where it can no longer remain as a liquid — which one of these two things happens? Does it freeze or boil? The surprising answer is it does both: first it boils and then it freezes! We know this because this is what used to happen when astronauts felt the call of nature while in space.

At What Temperature Does Water Freeze? Ocean water freezes at a lower temperature than fresh water due to its salt content, which interferes with the water’s ability to form ice. A look at how ice is formed will help to clarify why the addition of salt, or any solvent, requires a lower temperature to freeze. [6].

The Southern Ocean is getting less salty. Hereâs what that could mean for the rest of the world This is because the less dense fresh water has a tendency to get stuck on the surface of the ocean, trapping the warmer, deep water beneath it. It’s a process known as “stratification,” and it could cause big problems for Antarctica and possibly the rest of the world, according to some experts.

- A greater volume of ocean water due to thermal expansion will lead to a rise in sea level. Second, rising temperatures will cause the ice and snowfields to melt, thereby increasing the amount of water in the oceans. It should be noted that only the melting of land-based ice and snow increases sea level.

Arctic vs. Antarctic Sea ice differs between the Arctic and Antarctic, primarily because of their different geography. The Arctic is a semi-enclosed ocean, almost completely surrounded by land. As a result, the sea ice that forms in the Arctic is not as mobile as sea ice in the Antarctic. Although sea ice moves around the Arctic basin, it tends to stay in the cold Arctic waters. Floes are more prone to converge, or bump into each other, and pile up into thick ridges.

How cold is the north atlantic ocean? Then it gets gradually colder towards the north pole where it can get as low as -2 C, below freezing point for fresh water, but not for salty water. Then there is the fact that the deeper you go, the colder or warmer it gets. Yes, because water has the highest density at 4 C and that water sinks at the bottom. So it the water is above or under 4 C, it will tend to come up.

Introduction In contrast to fresh water, the salt in ocean water causes the density of the water to increase as it nears the freezing point, and very cold ocean water tends to sink. As a result, sea ice forms slowly, compared to freshwater ice, because salt water sinks away from the cold surface before it cools enough to freeze.

Why does the ocean get colder at depth? Cold, salty water sinks to the bottom of the ocean. The great ocean conveyor moves water around the globe. Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. 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.
