Which one of the following landforms would be created by outwash?

1) Moraines
2) Eskers
3) Drumlins
4) Erractics

I have read all I can, but can not get this one. I am sure it is not #4 - Erractics.

To determine which landform would be created by outwash, we need to understand what outwash is and how it influences the formation of different landforms. Outwash is a type of sediment that is carried and deposited by meltwater from a glacier. As the glacier melts, the water picks up sediment and carries it away.

Among the options given, three of them - moraines, eskers, and drumlins - can be created by the deposition of outwash sediments, while erratics are not formed from outwash.

1) Moraines: Moraines are accumulations of unsorted and layered sediment deposited by glaciers. However, while outwash contributes to the overall composition of moraines, they are primarily formed by the direct moving and melting of glacial ice.

2) Eskers: Eskers are long, winding ridges of gravel and sand that are formed by streams within or beneath glaciers. As the glacier retreats, meltwater flows through tunnels beneath the ice, depositing sediment and eventually forming eskers. Outwash plays a crucial role in the formation of eskers.

3) Drumlins: Drumlins are elongated hills formed by glaciers. They are composed of glacial till, which is a mixture of sediment that is eroded, transported, and then deposited by the glacier. While outwash is not the primary agent in drumlin formation, it can contribute to their outer layers.

Therefore, the correct answer is 2) Eskers.
