Considerable discussion regarded the evaluation of glacial erosion
in a region covered by polythermal ice, and the subsequent sediment flux to the ocean (an extension of the international "source-to-sink" research but with an emphasis on the role of glacial dynamics).
During the ice ages the North Estonian Klint was strongly influenced by glacial erosion
The Cuillins formed 60 million years ago and the distinctive jagged outline of the main ridge is the result of glacial erosion
Formed 60 million years ago, the distinctive jagged outline of the main ridge is the result of post-Ice Age glacial erosion
Valleys are usually very wide and shallower, with more gentle slopes, the result of glacial erosion
or meandering rivers.
The deposit is interpreted to have been formed by the concentration of uranium minerals leached from nearby highly radioactive intrusive rocks and deposited in an old riverbed channel, which was preserved from glacial erosion
by a cover of younger volcanic rocks.
Most of the depressions probably resulted from increased glacial erosion
and formed at the same time with the drumlins, as they are also elongated in the direction of ice movement.
