Process
Post-Glacial Rebound
Also Known As Isostatic Rebound
Geology
The rise of land masses after the removal of the enormous weight of ice sheets from the last glacial period, the recovery phase of glacial isostatic adjustment. Its direct raising effects are readily apparent in parts of Northern Eurasia, Northern America, Patagonia and Antarctica, and through ocean siphoning and continental levering its effects on sea level are felt globally, far from the current and former ice sheets.

Facts
TimescaleOngoing since the removal of the last glacial period's ice sheets 1 Driving ForceThe slow viscous flow of mantle material back beneath a landmass after the retreat of an ice sheet whose weight had depressed the crust. 1 Resulting FeatureRaises the land surface over centuries to millennia; GPS monitoring in northern Europe measures a peak uplift rate of about 11 millimeters a year in the Gulf of Bothnia even today. 1 SignificancePost-glacial rebound is measured with precise geodesy to constrain the viscosity of the mantle and must be corrected for when interpreting local sea-level change. 1 Connections

Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression.
Land bridge (Wikipedia)
Causes: Land bridge, Article textQuote, Causes: Land bridge, Article text
A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age.
Raised shoreline (Wikipedia)
Causes: Raised Shoreline, Article textQuote, Causes: Raised Shoreline, Article text
These landforms are formed by a relative change in sea level due to global sea level rise, isostatic rebound, and/or tectonic uplift.
