Why is glacier water blue?
A large piece of compressed ice, or a glacier, similarly appears blue. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible spectrum.
What is the front end of a glacier called?
The terminus is the end of a glacier, usually the lowest end, and is also often called a glacier toe or snout.
Why does the front end of a glacier melt?
The meltwater plume is lighter than the surrounding ocean water because it doesn’t contain salt. So it rises toward the surface, mixing the warm ocean water upward in the process. The warm water then rubs up against the bottom of the glacier, causing even more of the glacier to melt.
How can you tell an old moraine?
Two commonly used methods are measuring slope profiles and surface boulder weathering. High slopes usually indicate younger moraines and low slopes indicate older moraines because of slope degradation as a function of time.
What is a hummocky moraine?
hummocky moraine A strongly undulating surface of ground moraine, with a relative relief of up to 100 m, and showing steep slopes and deep, enclosed depressions. It results from the downwasting (i.e. thinning) of ice which is usually stagnant.
What is the difference between a recessional and terminal moraine?
Terminal and recessional moraines mark the farthest reaches of a glacier—its terminus—at a given point in time. If, on the other hand, a glacier retreats more quickly, and its terminal position changes every few years, it may leave a series of smaller recessional moraines, rather than a large terminal moraine.
