A cross-valley, ridge-like accumulation of glacial sediment that forms at the farthest point reached by the terminus of an advancing glacier. Also called an End Moraine. Moraine that marks the maximum
advance of a glacier.
Terminal moraines are piles of loose unconsolidated rock at the glacier's downvalley end. The rocks may be pushed there by the forward motion of the glacier or dumped from the glacier's rounded surfac
e. As glaciers melt, their remaining load of rocks is distributed in several ways. Rocks may be dropped in place by the melting ice; they may be rolled to the ice margins, or they may be deposited by meltwater streams. Collectively, these deposits are called 'glacial drift'. 'Till' refers to the debris deposited directly by the glacier. Rock debris rolls off the glacier edges and builds piles of loose unconsolidated rocks called 'glacier moraine'. 'Lateral moraines' form along the side of a glacier and curl into a 'terminal moraine' at the glacier's downvalley end. Drift and moraines are valuable to geologists because they outline the boundaries of past glaciations.
A shock wave inside the heliopause where the supersonic solar wind abruptly slows from an average speed of 500 km s^-1 to subsonic and becomes denser and hotter.

The downvalley end of a glacier. It is sometimes referred to as the glacier snout. The lower-most margin, end, or extremity of a glacier. Also called Toe, End or Snout. The lowest end of a glacier, al
so called glacier snout, glacier front or glacier toe. The term, the plural of which is either 'terminuses' or 'termini', is applicable primarily to glaciers with well-defined tongues, and to ice streams.
