Quick Summary

In geology, an upwarp refers to a broad, gentle uplift of the Earth's surface. This geological process can be described as a very broad anticline with gently dipping limbs, caused by differential uplift. It is essentially a large upward flexure of the Earth's crust.12

This type of uplift is also known as warping or epeirogeny, distinguishing it from orogeny, which is associated with mountain building. The land can be differentially uplifted, resulting in an upwarp or a broad arching of the surface. This bending of rocks into an anticline or dome is also termed uparching. Uplift can also occur due to the removal of massive ice sheets, causing an elastic rebound of the land.345
