Depositional features are landforms that are created by the deposition of sediments carried by glaciers. Glaciers are large masses of ice that move slowly over the land, picking up rocks, soil, and other debris along the way. As glaciers melt, they deposit these sediments, creating a variety of landforms. Some of the common depositional features in glacial landforms include:

Moraines:
Moraines are ridges or mounds of sediment that are deposited by glaciers. There are several types of moraines, including lateral moraines, which form along the sides of glaciers, and terminal moraines, which form at the end of glaciers. Medial moraines are formed when two glaciers merge and their lateral moraines combine. Moraines are composed of a mixture of different-sized sediments, ranging from large boulders to fine silt.

Drumlins:
Drumlins are elongated hills that are formed by the deposition of glacial sediments. They are typically smooth and rounded in shape, with a steep side facing the direction of glacier movement and a more gentle slope on the other side. Drumlins are often found in groups called drumlin fields and are composed of till, which is a mixture of clay, sand, and gravel.

Eskers:
Eskers are long, winding ridges of sediment that are deposited by meltwater streams that flow within or beneath glaciers. They are formed when sediments are deposited along the course of a subglacial or englacial meltwater stream. Eskers can range in size from a few meters to several kilometers in length and are composed of sand and gravel.

Kames:
Kames are small, cone-shaped hills that are formed when sediment is deposited by meltwater streams on the surface of a glacier. As the glacier melts, the sediment is left behind, creating a mound or hill. Kames are typically composed of sand and gravel and can be found in clusters called kame fields.

Kettles:
Kettles are depressions or small lakes that are formed when a block of ice becomes buried by glacial sediments. As the ice melts, it leaves behind a hole or depression in the ground. Kettles can vary in size and shape and are often surrounded by a ring of sediment called a kettle rim.

In conclusion, depositional features in glacial landforms are created by the deposition of sediments carried by glaciers. These features include moraines, drumlins, eskers, kames, and kettles. They are formed through a combination of glacial movement, meltwater streams, and the melting of glacial ice, resulting in a variety of distinct landforms.
