How can a rise in temperature cause a change in a polar ecosystem?
a. sea levels would rise
b. sea levels would fall
c. sea levels would fluctuate
d. sea levels would stay the same

The correct answer is sea level will rise.

The rise in temperature in the polar ecosystem will increase the sea level. The habitat of the polar bear will be disturbed as there will be a significant increase in the sea level.

The rise in temperature will melt the ice and it will be converted into water and loss of habitat of polar bear will be observed.

answer: populations of walruses and polar bears will decline

explanation:

you put it

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
