When the sea level changed due to an
alteration in the volume of water in
the oceans, or a change in the shape
of an ocean basin, therefore changing
the amount of water it is able to hold
Isostatic change
Result of increase or decrease in
height of land; sea level rises as land
height decreases, and sea level falls
as the height of the land increases
Local sea level change
Ice sheet
Biggest ice sheet:
Antarctic ice sheet, hold
90% of Earth's freshwater
A chunk of glacier ice that
covers the land
surrounding it and is
greater than 50,000 km
Since they are found on
land, their melting does
contribute to the rise of
sea levels
