Question

Quizplus · Accepted Answer

Drumlins are elongated hills, often in the shape of an inverted spoon, streamlined in the direction of glacial movement. Eskers are long, winding ridges of gravel and sediment that form in the beds of meltwater streams flowing beneath glaciers. Kettles are shallow, sediment-filled depressions that form when a block of ice becomes detached from a glacier and is buried in sediment or till. Horns are sharp, jagged peaks that form when several glaciers erode a mountaintop from different sides.
