Question

PLATO USERS! PLEASE HELP!!!

This graph gives information on changes in sea ice extent in the Arctic Ocean over a 30-year span. The overall trend shows _____ in sea ice extent. To address the trend, scientists need to ask themselves ______ ? One direct consequence of the trend is that _______ .


Blank 1:

a decline

a rise

no change


Blank 2:

What happens to polar animals when sea ice melts

How did global rainfall amounts change during the same period

Why is sea ice melting so much and so fast

What were the levels of sea ice extent from 1948 to 1978


Blank 3:

ocean salinity will decrease

Arctic regions will cool

worldwide rainfall amounts will drop

sea ice will emerge in temperature climates

Answer 1

1. a decline - The overall trend of the ice surface has been a constant decline, with approximately a third part less ice since 1978.

2. Why is sea ice melting so much and so fast - The Earth's climate is a complex interconnected system. Thus, it is difficult to determine the exact causes for the ice melt in the Arctic Ocean.

3. ocean salinity will decrease - The ice in the Arctic Ocean is mainly composed of fresh water. Thus, if all of it were to melt, the ocean salinity will decrease considerably and thus affect the global ocean currents.
