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.

Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...

2016年9月13日 · Glacier Bay and the surrounding area show the fastest rates of isostatic uplift on the planet. Uplift of about 5.5 meters has taken place in Glacier Bay since the retreat of glacial ice beginning about 250 years ago.

2016年11月10日 · Our study shows that even small LGM ice caps can dominate present-day rock uplift in tectonically active regions. For half a century, the cause for recent uplift of the European Alps has been...

Glacial isostatic adjustment is the ongoing movement of land once burdened by ice-age glaciers. The last ice age occurred just 16,000 years ago, when great sheets of ice covered much of Earth's Northern Hemisphere.

2024年5月28日 · Glacial Isostatic Adjustment (GIA), sometimes referred to as post-glacial rebound, is a geological phenomenon that occurs when large ice sheets recede, allowing the Earth’s crust to slowly ‘bounce back’ from the weight of the ice.

2025年1月3日 · This rate of the Earth’s crust rising back up is called Isostatic rebound, or post-glacial rebound or glacial isostatic adjustment. Regions that experienced heavy glaciation during the Ice Age, such as parts of Scandinavia and Canada, are where isostatic rebound is …

2009年7月1日 · The pattern, which comprises a region of maximum uplift centred over eastern Scotland and a zone of subsidence throughout most of England, is clearly correlated with the thickness extent of the most recent British–Irish ice sheet (BIIS) (e.g. Shennan et al. 2006b and references therein).

Isostatic rebound refers to the elastic deformation of a material caused by the removal of an external load. In particular, geologists and engineers use this to describe how Earth’s crust responds to large weight or pressure changes from a post-glacial rebound.

Isostatic rebound is a factor that influences the water levels in the Great Lakes, which affects recreational use, Great Lake shipping, and shorelines. Isostatic rebound is expanding the size of Ontario as Hudson and James bays drain to the north.
