The medial moraine is the double line of debris running down the centre-line of the glacier. Lateral moraines can rise up to 140 meters (460 ft) over the valley floor, can be up to 3 kilometers (1.9 mi) long, and are steeper close to the glacier margin (up to 80 degrees) than further away (where slopes are typically 29 to 36 degrees).

Till is the material that makes up ground, lateral and (not always present) medial moraines. Ground moraine consists of material that was once beneath the glacier and was transported by it and deposited across wide areas of the former glacier bed. The lateral moraines comprise that eroded material which is carried along at the sides of a glacier.
Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki
[22], [23] Sediments that form the lateral moraines can be the result of frost weathering of the valley wall as the glacier passes through a region or sediment deposition by streams flowing into the glacial valley. [22] These sediments settle into a ridge as the glacier retreats. Medial Moraine: Nuussuaq Peninsula, Greenland.
The major part of the Kettle Moraine area is considered interlobate moraine, though other types of moraine features, and other glacial features are common. [1] The moraine is dotted with kettles caused by buried glacial ice that calved off the terminus of a receding glacier and got entirely or partly buried in glacial sediment and subsequently ...
A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment.
