* Glaciers are massive bodies of ice that slowly move and erode the land beneath them.
* As glaciers melt, the water carries with it a variety of rock debris, ranging from fine silt to large boulders.
* This debris is deposited as the water flows, creating a mix of unsorted sediment called glacial till.
Key characteristics of glacial till:
* Unsorted: Contains a wide range of particle sizes, from clay to boulders.
* Angular: Rocks are often angular and jagged due to the grinding action of the glacier.
* Poorly stratified: There is no clear layering or sorting of the sediment.
Examples of glacial till:
* Moraines: Ridges of till deposited at the edges or end of a glacier.
* Drumlins: Elongated hills of till shaped by the flow of ice.
* Kettles: Depressions in the landscape formed by blocks of ice that melted after being buried by till.
