1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
1. there are such large differences between the changes in the amount of sea-ice present in the two polar regions because of the strong northward winds that are present. the winds either decrease or increase the amount sea ice that is found in both polar regions. the climate change also affects the amount of ice in both of the polar regions.
ReplyDelete2.The purpose of sea ice in these regions is to isolate the warmer below the ice against the frigid temperatures of the poles above. the consequences is that the antarctic sea interacts with the global climate system much more differently than the arctic sea, and because of the sensitivity of the ice coverage, it changes the ice coverage by the strengths of the winds around the continent.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThere is such a large difference between the changes in the amount of sea-ice present in the two polar regions due to the regional changes caused by changes in wind, which affect the ice cover through ice drifting and air temperature. These wind changes cause an increase in northward winds and cause the sea-ice to expand outwards.
2. The purpose of the sea-ice is to reflect heat from the sun and provide a habitat for marine life. As well as this the ice is able to insulate the warm ocean from the extremely cold atmosphere above. The consequences for this are that the Antarctic sea ice cover interacts with the global climate very differently than the ice covers do in the Arctic. This causes the Antarctic to be more sensitive and vulnerable.
THe differences in the amount of sea-ice present in the Arctic and Antarctic is due to the winds, the slight increase in the Antarctic region is due to the Antarctic not being land locked, unlike the arctic which is surrounded by land and thereby does not allow for expansion.
ReplyDeleteThe sea-ice acts as a reflecter of sunshine, that keeps marine life, during the winter insulating the warmth of the ocean. The different consequences of sea-ice,in the arctic and antarctic, is that the antarctic is more able to expand due to the winds being able to change the environment.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteChanging winds affect ice formation through temperature and ice drifts, causing ice to form more in some regions and less in others.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
Sea ice allows marine species to survive by shielding them from the elements and reflecting sunshine. In late summer, the ice is thinnest and least effective in both the Arctic and the Antarctic. In the Antarctic, however, the winters bring several-meter thick ice drifts which insulate the ocean. The Arctic though, keeps losing ice.
1. There is such a large difference between the changes in the amount of sea-ice present in the two polar regions because of changes in the winds, which affect both ice drift and air temperature. In some places, northwards winds have increased (the ice is blown away), which has caused the ice cover to expand outwards from Antarctica. In some areas the export of ice away from Antarctica has increased, and in other areas it has decreased.
ReplyDelete2. Sea ice is crucial to the environment because it reflects heat from the sun (so that the Arctic and Antarctic can continue to have cold climates), and it also provides a habitat for marine life. The different consequences are that the Arctic had undergone dramatic ice losses, which the Antarctic has gone through increases, and the results suggest large changes in the ocean surrounding Antarctica, which is very sensitive to the cold produced by the increasing amount of sea ice.
1. The large difference between the amount of see-ice present in the two plar regions is so different because of the shift in winds hat carry ice to and from the regions. Ice in the Arctic region is shrinking, as the winds are blowing the ice away and ward air towards the arctic, while the antarctic is receiving more ice from the shift, which is contributing to this change.
ReplyDelete2. The sea-ice has several purposes, some of which is to reflect sunlight away from the water and provide a habitat for animals in the polar regions.The consequences for the arctic is the sea-ice continues to melt and drift away is large changes in ocean currents and loss of species that rely on the ice to survive, while in the antarctic, there will, be similar results except for the loss of species as there are very very few in the antarctic.
1. There is such a large difference between the changes in the amount of sea-ice present in the two polar regions because changing winds affect ice formation. This effects the ice shift and temperature. This causes ice to form more in some areas than others. SOme areas have decrease in ice because it has been (blown away) while others receives the ice to the amount increases.
ReplyDelete2. The sea ice is crucial to insulating the marine life and reflects the sunshine. Depending on the season the ice can be several meters thick or thin in which the marine life is at risk. This is specifically shown in the drifting of the ice.
1. There is such a large difference between the changes in the amount of sea-ice present in the two polar regions because of wind change. From wind change, it causes ice formation to occur better in one location than in others. It also caused a shift in temperature having an effect on shifting the ice formation.
ReplyDelete2. The purpose that the sea-ice have in these was to act like sunglasses. The sea-ice protected marine life from the sunshine. The different consequences for the Arctic and Antarctic are how much marine life are living in an area and how much marine life was lost.
1. There is such a large difference between the changes in the amount of sea-ice present in the two polar regions because of shifts in wind patterns. These wind changes in turn cause ice drift to change, changing in turn the total ice cover.
ReplyDelete2. In these regions sea ice serves the purpose of reflecting heat from the sun in order to sustain the local marine life. In the Antarctic ice coverage is expanding lightly whereas in the Arctic ice coverage is decreasing.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThere is such a large difference between the changes of amount of sea-ice in the two polar regions because of the shift of wind patterns, which causes ice formation to occur better in a certain location than in others. It was also caused by a shift in temperature which had an effect on shifting the ice formations.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
In these regions, sea ice serves the purpose of acting like sunglasses for the marine life below, protecting them from the sunshine. The different consequences for the Arctic and Antarctic are the huge amount of marine life that was living in these areas, and how much of it was lost due to the changing sea-ice.
1. Changes in winds, which have an affect both on ice drift and air temperature, is the cause of the large differences in the amount of sea ice present. The wind can either cause the ice amount to grow or shrink depending on the way in which it take effect on the ice.
ReplyDelete2. Sea ice is essential because it reflects heat from the sun which makes these places able to maintain their cold climate. It is also a habitat for marine life, which is necessary. The consequences are mainly for the sea animals and their not being able to survive. The Antartic and Arctic interact with the global climate in much different ways.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThere is such a large difference between the changes of amount of sea-ice present in the two polar regions because of the shift of wind patterns, which allows for better conditions of ice formation in some areas than others. In a place with little wind, the ice can form easily, but if the wind is strong it can blow it away. It was also caused by a change in temperature which obviously affects the formation of ice. If the temperature is too high, the ice will not form, or melt faster.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
The sea-ice reflects sunlight away from the water and provides shelter for animals in the arctic and antarctic. The consequences for the arctic and antarctic is a loss of ice, and therefore an increase in ocean temperature. The ice is also home to animal species, so if the ice is lost, the species are lost as well.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThere is a large difference between the changes in the amount of sea-ice present in the two polar regions because of a change in temperature. When the temperature is too high, it is difficult for ice to form for obvious reasons. The differences were also caused by a shift in wind patterns. This shift allows for better ice formation in some areas than others. The presence of a lot of wind can blow ice away, but when there is little wind ice forms easily.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
Sea-ice serves the purpose of providing shelter for animals in both the arctic and antarctic. It also reflects sunlight away from the water surrounding it. This lowers the overall temperature of the ocean. A loss in ice cover causes an increase in temperature as well as a loss of many of the species living there.
1. There is a difference in the ice coverage in the arctic and antarctic because of wind patterns and temperature. With stronger winds and higher temperatures, it is harder for ice to form. These conditions differ between regions, causing differences in ice formation.
ReplyDelete2. The ice reflects sunlight, creating a preferable habitat for animals to live under the ice. When conditions change, species may not be able to live there anymore. They may also not have a habitat due to the lost ice.
1. The major reasons that there is such a large difference between the changes int he amount of sea-ice in the two polar regions is because of the change in winds, which both affect ice drift and air temperature and therefore causes many differences. Also, the wind can cause more ice to be created or allow the ice to melt faster due to the way in which it takes and the heat or cold that is brought to the area.
ReplyDelete2. The sea-ice is imperative to the environment because it reflects heat from the sun in which the Arctic and Antarctic can continue to have cold climates and support animal life such as polar bears ands seals, which are key to the Arctic environment. The major consequences is that the Arctic has seem high levels of ice melting and the Antarctic has seen dramatic increase. These results could create large changes in the ocean around the Antarctic which is extremely sensitive to the cold created by the ever increasing amount of sea ice.
1.) The reason that there is such a large difference between the changes in the amount of ice in both regions is partially due to the change in winds which help affect ice drift and the overall temperature. As well as the fact that depending on the wind allows for changes in temperature allowing for more ice in one region and less in another.
ReplyDelete2.) This ice is important to the environment because of the fact that it helps actually support the cold climates they are in. This is because of the fact that it reflects sun rays, which helps aid the ecosystems that certain animals are thriving in.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThere is a large difference because of temperature and the wind patterns. With the stronger winds and higher temperatures, ice doesn't form as quickly, making the amount of ice different in each region.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
The sea-ice is important because it reflects the sunshine which in turn protects the marine life. The ice also keeps the regions cold, in order for the creatures that live there to survive.
The major changes are cause by a rise in temperature and change in wind patterns. Wind patters can change the drifting patter of ice. Wind also makes it harder for ice to form as does temperature.
ReplyDeleteThe largest effect the loss of ice in certain regions is the destruction of marine life. Ice can cool waters by reflecting the sun and absorbing ice. Without this service, a lot of marine life which prefer colder waters , can no longer live in said regions.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDeleteThe large difference is due to the changing wind patterns and temperature. With the higher temperature, the ice does not form as quickly. With the changing wind patterns, the ice moves in different directions that it usually would, causing an ice drift.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
in these regions, the greatest purpose of the sea-ice is that the ice reflects the light. This causes animal life to be more optimum under the ice rather than on top of the ice. The consequences for the Arctic and Antarctic is that the ice melts and could cause fluctuations in the temperature and animal habitats that live in those regions.
1. The difference in sea-ice changes in the two polar regions can be attributed to changing wind patterns. The changing wind patterns blow antarctic sea ice further away from the antarctic, allowing for even more ice to form. as the arctic is actually a land mass, this effect is not present in the northern pole.
ReplyDelete2. The sea-ice is important in these regions because it reflects sunlight, which in turn helps protect sea life. The main consequences of loss of sea-ice in these regions is the destruction of an environmental barrier which was essential to the ecosystem, which would in turn throw the ecosystem into chaos.
1. Why is there such a large difference between the changes in the amount of sea-ice present in the two polar regions?
ReplyDelete- Ice drift(wind, ice exportation, and solar radiation cause the main differentiation in ice mass at the northern and southern poles. the wind creates a fluxing temperature which dictates the drift and radiation that the ice absorbs. exportation obviously diminishes the supply.
2. What purpose does the sea-ice have in these regions? What are the different consequences for the Arctic and Antarctic?
- Sea-ice provides a habitat for native organisms to thrive in, and also maintains the regional and to some extent global temperature. the consequences for the different poles is that during warmer seasons, the wildlife in either will decrease/increase due to temperature and amount of ice.
1. the difference is due to the wind patterns which then changes the wind patterns which dictates the temperature and lessens the amount of ice even faster if warmer.
ReplyDelete2. The sea ice is used to control the temperature and act as a different habitat for organisms than the surrounding. If we lose them we lose certain the organisms and the certain temperature that is needed
1. The change in the amount of sea ice in the polar regions is due to the changing winds.
ReplyDelete2. The sea-ice reflects sunlight and supports marine life. It also insulates the warm ocean from the frigid conditions above the ice sheets. In the Arctic there has been a massive amount of ice loss while in Antarctic there has been a slight increase.
1) The change in ice levels is due to change in the directions of the winds
ReplyDelete2) The ice regulates the temperature around it. it reflects light to make sure it doesn't over heat, as well as absorbs warmth
