1. Moraines:
* Terminal moraine: A ridge of till (unsorted glacial sediment) deposited at the furthest extent of a glacier.
* Recessional moraine: A ridge of till deposited as a glacier retreats and pauses for a period of time.
* Lateral moraine: A ridge of till deposited along the sides of a glacier.
* Medial moraine: A ridge of till formed when two glaciers merge, and their lateral moraines join together.
2. Outwash Plains:
* Outwash plain: A flat, gently sloping area of sand and gravel deposited by meltwater flowing from a glacier.
* Kettles: Depressions in an outwash plain formed when blocks of ice left behind by a retreating glacier melt.
* Eskers: Long, winding ridges of sand and gravel deposited by meltwater flowing in tunnels beneath a glacier.
3. Drumlins:
* Drumlins: Elongated, tear-shaped hills of till deposited beneath a glacier. They are often found in clusters called "drumlin fields."
4. Till Plains:
* Till plain: A broad, flat area of unsorted till deposited by a glacier.
5. Erratics:
* Erratics: Large boulders transported by glaciers and deposited in locations far from their source.
6. Glacial Lakes:
* Glacial lakes: Lakes formed by glacial erosion or deposition. Examples include:
* Kettle lakes: Formed by the melting of ice blocks left behind by retreating glaciers.
* Tarn lakes: Formed in cirques (bowl-shaped depressions) carved by glaciers.
* Paternoster lakes: A series of small, interconnected lakes formed in a valley by glacial erosion.
7. Other Depositional Features:
* Glacial flour: Fine, silt-sized sediment produced by glacial erosion.
* Varves: Annual layers of sediment deposited in lakes by glacial meltwater.
* Loess: Fine-grained, windblown sediment deposited by glacial meltwater.
These are just some of the many landforms created by glacial deposition. Glaciers play a significant role in shaping the Earth's surface, leaving behind a diverse array of features that provide valuable insights into past climates and geological processes.
