  • Understanding Glacial Deposition: 4 Key Landforms
    Here are 4 glacial deposition features:

    1. Moraines: These are ridges of unsorted rock debris (till) deposited by glaciers. There are different types of moraines:

    * Terminal Moraine: Marks the furthest extent of a glacier.

    * Lateral Moraine: Forms along the sides of a glacier.

    * Medial Moraine: Forms in the middle of a glacier, where two lateral moraines merge.

    * Recessional Moraine: Forms as a glacier retreats, leaving behind a series of moraines.

    2. Outwash Plain: This is a flat, gently sloping plain composed of sand and gravel deposited by meltwater streams flowing from a glacier. Outwash plains are often characterized by braided stream channels and kettle lakes.

    3. Drumlins: These are elongated, oval-shaped hills composed of till. They are typically oriented parallel to the direction of ice flow. Drumlins form when a glacier flows over a pre-existing deposit of till.

    4. Eskers: These are winding ridges of sand and gravel deposited by meltwater streams that flowed within or beneath a glacier. Eskers can be quite long and often form sinuous patterns on the landscape.

    These are just a few examples of glacial deposition features. There are many others, including kames, kettle holes, and glacial erratics.
