What are the sequence of landforms when a glacier retreats?
The figure you see above is of receding glacier landforms..
How Eskers are formed?
After the ice has gone (retreating glacier), the position of a former ice tunnel is marked by a long, sinuous ridge of sediment known as an esker (stream-bed deposit remains, forming a ridge). Eskers are long sinuous ridges of sediment deposited by streams that ran under or within a glacier. The sediment deposited by these streams becomes an esker after the ice has melted.
• Sinuous ridges of stratified till
• Form in tunnels under the ice sheet
• Some times 100 km long or more
• They follow the general follow the general ice flow direction.
