Changes in Sea Level

The main causes of change in sea level include thermal expansion of oceans and melting of the glaciers and ice caps.

Sea level changes show geographical variation because of several factors, including the distribution of changes in ocean temperature, salinity, wind pattern, and ocean circulation.

The following graph shows changes in sea level.
