These can be formed out of till which is all material directly deposited by a glacier, or out of fluvio-glacial material which is material deposited by meltwater streams (e.g. Kame Terraces.) There are two types of till; Ablation till which is material deposited by stagnant or retreating glaciers, or Lodgement till which is material deposited by advancing glaciers.
Moraine is the general term for material of all shapes and sizes once transported by glaciers or ice sheets that have now melted away. There are two types of moraine which exist only whilst the glacier exists. These two are called supraglacial moraine, and englacial moraine. Supraglacial moraine is material on the surface of the glacier made up of loose rock debris and dust. This forms other types of moraine later e.g. lateral and terminal when the glacier starts to retreat. Englacial moraine is any material trapped in the ice. It includes material that’s fallen down crevasses and the rocks being scraped along the valley floor. Moraine landforms can be found all over the world, but two examples would be by the Gorner Glacier in Switzerland and the Baffin Island glacier in Canada. There are six different types of moraine which form recognisable landforms, each differing in how and where it was deposited. ...
