Describe the four moraine landforms found in glacial environments.

'Moraine' is a term given to pieces of rock transported by a glacier, and can my divided into four different categories.

'Ground Moraine' is a collection of rock dragged underneath a glacier as it moves downhill. Often noticeable in uneven ground on valley floors where glaciers once were.

'Lateral Moraine' is found on either side of a glacier, and is made up of pieces of often angular rock that have fallen onto the glaicer from the valley sides.These pieces often fall because of freeze-thaw weathering, and line either side of the glacier.

'Medial Moraine' is very similar  to lateral moraine - simply, when two tributary glaciers merge while flowing downhill two sets of lateral moraine meet to form one central ridge. This forms a 'Y' shaped ridge of moraine in the middle of the glacier, pointing downhill.

Finally, 'Terminal Moraine' is the term given to the large pile of shattered rock found at the downhll end, or snout, of a glacier. This is rock that has been 'bulldozed' by the flow of the glacier, and shows the furthest reach of the ice.
