However, SE England is sinking by a process known as isostatic adjustment.
The process is known as isostatic rebound, or isostatic uplift.
What happens and does happen over long periods of geologic time, we're still coming out of our last ice age, and as the ice melts from that, there is something called isostatic rebound I think is the technical term.
As the ice melted, the release of this enormous weight resulted in the landmass slowly tilting back up in the north or down in the south, a process called isostatic adjustment.
He finds that the movements (termed isostatic) which geologists recognise as taking place deep in the Earth's crust, indicate an age of the same order of magnitude xi as that which is inferred from the statistics of denudative history. [
Earlier projections apparently failed to account for rebounding changes in the Earth's crust following the last Ice Age referred to as "glacial isostatic adjustment".
Right at the end of the last Ice Age, Earth experienced the greatest thrust of the glacial isostatic adjustment post-glacial rebound and its opposite effect.
Glacio-isostatic evidence indicates deglaciation was underway by the beginning of the Holocene and maximum uplift occurred between 8 and 7 ky BP and even earlier in many areas.
The Eurasian and Laurentide Ice Sheets were responsible for most of the glacio-eustatic decrease in sea level (about 120 m) during the LGM. The pattern of postglacial isostatic rebound suggests that the ice was thickest over Hudson Bay.
He concluded that the cyclic glaciations were related to orogenic uplift, changing insolation (Milankovitch cycles), ice-albedo feedback, and the effect of isostatic adjustments to the loading of continental crust by glacial ice sheets — all topics still being actively discussed today.
