Understanding Driftage: The Gradual Movement of Sediment and Soil

Driftage refers to the gradual movement of sediment or soil downslope due to gravity. It can occur through a variety of mechanisms, including:

1. Gravity: The force of gravity causes sediment or soil particles to move downslope over time.
2. Water flow: Water flowing downslope can carry sediment or soil particles with it, leading to driftage.
3. Wind: Strong winds can blow sediment or soil particles away from their original location, leading to driftage.
4. Ice: Glaciers and ice sheets can cause driftage as they move and scrape along the landscape.

Driftage is an important geological process that helps shape our planet's landscapes over time. It plays a key role in the formation of mountains, valleys, and other geological features.
