4. thermal expansion of oceans |
A) 1 and 3
B) 1 and 3
C) 2 and 3
D) 2 and 4
Correct Answer: C
Solution :
Greenland ice sheet melt water, which moves to the sea under the ice in contact with the land surface, may transport solids or dissolved material such .as iron to the ocean. Measurements of the amount of available iron in melt water from the Greenland ice sheet shows that extensive melting of the ice sheet might add an amount of iron to the Atlantic Ocean equivalent to that added by airborne dust. This would increase biological activity in the Atlantic.You need to login to perform this action.
