1 In 2010, the Greenland ice sheet melted substantially. In response, the bedrock below
the ice sheet gradually rose. This environmental
change has led to -
a lack of change in the stability of the
marine ecosystem, as the uplifted bedrock
and melting sea ice have combined to form
a different type of landscape.
® a decrease in the stability of the marine
ecosystem, as chunks of melting sea ice
have decreased the salinity of the water off
Greenland's coast.
© an increase then decrease in the stability of
the marine ecosystem, as organisms have
adapted to cold weather and developed
features allowing them to tolerate warmer
temperatures.
O an increase in the stability of the terrestrial
ecosystem, as the bedrock below the ice
sheet has been colonized by new types of
plants and animals.​
