Glacial Isostasy
Post-glacial crustal adjustment where areas covered by thick ice sheets experience uplift following ice sheet melting, altering sea level position relative to the land.
Real World
Scandinavia is rising at up to 8 mm per year due to post-glacial isostatic rebound following the melting of the Fennoscandian Ice Sheet, causing the Baltic Sea coastline in Finland to emerge by roughly 6 metres per century.
Exam Focus
When 'explain' questions ask about isostatic rebound, include both the loading mechanism and the timescale of recovery.
