Caused due to glacier periods, the last glacier period ended 11,000 years ago. Since then temperature has increased melting ice sea levels are predicted to have rose125metres, but the rate is increasing due to climate change, and also thermal expansion is occurring
During glacial periods sea levels decrease due to ice volume being restricted but in phases the ice melts causing volume increase
What is Isostatic change?
Localized change caused by the mass of glaciers causes the land to sink, creating local decrease whereas when they melt this is released.
Such as scotland
