A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical pothole drilled in solid rock underlying a glacier either by water descending down a deep moulin or by gravel rotating in …

In Earth science, a pothole is a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found carved into the rocky bed of a watercourse. Other names used for riverine potholes are pot, (stream) kettle, giant's kettle, evorsion, hollow, …

Some large potholes are over 50 feet deep. Where Can a Pothole Be Found? Potholes can be found in desert plains and badlands regions where rock layers are exposed on the ground and able to collect standing water. Potholes can also be found in river and stream beds that have exposed rock layers.

Mar 1, 2015 · Potholes are cylindrical holes drilled into the bed of a river that vary in depth & diameter from a few centimetres to several metres. They’re found in the upper course of a river where it has enough potential energy to erode vertically and its flow is turbulent.

A river pothole is a cylindrical, bowl-shaped, or irregular hollow that is usually deeper than wide. It is formed in the rocky bed of a stream by either the grinding action of sediment whirled around by stream eddies or the force of fast flowing water.

Jun 23, 2024 · A pothole in a river is a cylindrical, bowl-shaped, or irregular hollow that is usually deeper than wide. It is formed in the rocky bed of a stream by either the grinding action of sediment whirled around by stream eddies or the force of fast flowing water.

Potholes that happen a long way from streams and valleys, at times high up on slopes and mountains, are clarified by geologists as the impact of the incredible ice periods of the Quaternary. Apparently, during this time, there were potholes shaped when the ice liquefied, as waterways streamed underneath the ice and on its surface.

Potholes on the River Ure, close to Ayesgarth Falls. They are formed when sediment and other material carried by a river scour the bed. Where depressions exist in the channel floor turbulent flow can cause pebbles to spin around and erode hollows through abrasion/corraision.

The Science Potholes - cylindrical or hemispherical holes formed by erosion in bedrock rivers - are one of the principal ways in which rivers erode landscapes. Once initiated as small depressions on rock surfaces, potholes can deepen and widen owing to abrasion by sediment.

Formed by water action A river pothole is a cylindrical, bowl-shaped, or irregular hollow that is usually deeper than wide. It is formed in the rocky bed of a stream by either the grinding action of sediment whirled around by stream eddies or the force of fast flowing water.
