Question

How can a rise in temperature cause a change in a polar ecosystem?

A. Sea levels would stay the same
B. Sea levels would fall
C. Sea levels would fluctuate
D. Sea levels would rise

Answer 1

i think it is answer b

Answer 2

The correct answer would be D. sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.
