Question
In Greenland the polar ice sheets are melting on the surface much more frequently and at a larger rate than ever before. These polar ice sheets are found completely on land. a. If these ice shelves melt completely, how will this affect the water levels in the Arctic Ocean and why? b. Would your answer be different if the ice shelf was instead a glacier in the ocean before melting and not on land? Explain your answer What are the major properties that distinguish different amino acids from one another? What roles do these differences play in the structure and function of a protein? Answer the following based on the information provided on these nutritional labels:Explanation / Answer
In Greenland the polar ice sheets are melting on the surface much more frequently.
a) It these ice sheets melt completely the water level in the Arctic oceans would increase 6m or 20ft. Because there is an agreement between the absolute mass loss and acceleration of mass loss. From the study it has been found that in 2006, a combined mass loss from Greenland and Antarctic ice sheets is 475 ( +/- )158 Gt/yr, equivalent to 1.3(+/-) 0.4 mm/yr sea level rise. Now the combined acceleration in the ice sheet loss over the last 18 year from Greenland and Antarctic is 36.3 (+/-) 2 Gt/yr^2. This acceleration is 3 times larger than for mountain glaciers and ice caps. So melting of ice sheet would be a great contributor for sea level rise.
b) Ice shelf is permanently floating ice sheets that connect to a landmass. Ice shelves are common in the coast of Antarctica. It can form where ice flows from land to the cold ocean. Therefore, ice shelves would not effect the sea level before melting.
