10. Depositional landforms of glacier

Glacial debris includes eroded materials such as a mass of boulders, pebbles, sand, mud, fragments of rocks, gravel, and dirt. These debris gets deposited in the low lying areas and form depositional features
like moraines, drumlins, eskers, kames and outwash plains.

 

Moraine: Landforms formed by unstratified and unsorted deposits of sediment that form through glacial erosion are called moraines.
They are of various shapes and sizes, like ground, terminal and lateral moraines etc.

 

Drumlins are elongated deposits of glacial moraines, teardrop-shaped hills of rock, sand, and gravel that formed under moving glacier ice. They resemble giant inverted teaspoons or half cut eggs. They can be up to 2 km long.

 

 

Esker is a long narrow ridge or mound of sand, gravel, and boulders deposited by a stream flowing on, within, or beneath a stagnant glacier. They run parallel to a glacier.

 

An outwash plain is formed by glacial sediments in front of a glacier where the sediments carried by the melting ice at the terminus of a glacier are deposited over a wide area  .It appears as an extensive
accumulation of sand, gravel and silt.
