Hi, I really got major problems with any piece of mathematical work. I took an a course in my university not knowing that it includes maths so it looks pretty bad now. Would be great if you could help me with this question:
1. Earth’s oceans cover roughly 70 percent of our planet, to an average depth of about 3.5 km. The density of ice is 0.9
that of water (that is why ice floats). Over a recent seven year period, several ma jor sections of Antarctic ice have broken off.
Among these are the Larsen A ice shelf, which measured 1,500 sq km, and which broke off in 1995. The 1,200 sq km Wilkins
ice shelf fell off in 1998 and the 14,500 sq km Larsen B dropped away in 2002. If each of these was 2.0 km thick (the average
ice thickness in Antarctica) and melted completely, how much would they have contributed to the global sea level rise over this
period? Note that the Antarctic ice sheet sits on a land mass so that if it melted the oceans would rise. By contrast, in the
Arctic, the ice floats on the Arctic Ocean so if it melted sea level would not be affected very much. [5 marks]
tl;dr, but should prolly be posted in hw help =\
