What Causes Isostatic Adjustment?

Tectonic stress and climate are both capable of redistributing weight and, therefore, both cause isostatic changes. Tectonic stress can displace rock and change the temperature of rock (and therefore its density). Climate activates erosion and deposition and can cause glaciation.

What is isostatic adjustment and what are its causes?

Glacial isostatic adjustment is the ongoing movement of land once burdened by ice-age glaciers. ... Though the ice melted long ago, the land once under and around the ice is still rising and falling in reaction to its ice-age burden. This ongoing movement of land is called glacial isostatic adjustment.

What causes isostatic uplift?

Isostatic rebound is the uplift and readjustment of the land after a glaciation. During the last glacial maximum, and other ice ages, the weight of the ice sheets pressed down on the land, causing it to sink and depress.
