A large proglacial plain of sediment is called a sandur (a.k.a. an outwash plain), and within that area, glaciofluvial deposits can be tens of metres thick. In situations where a glacier is receding, a block of ice might become separated from the main ice sheet and become buried in glaciofluvial sediments.

A moraine is sediment deposited by a glacier. A ground moraine is a thick layer of sediments left behind by a retreating glacier. An end moraine is a low ridge of sediments deposited at the end of the glacier.

The various unsorted rock debris and sediment that is carried or later deposited by a glacier is called till. Till particles typically range from clay‐sized to boulder‐sized but can sometimes weigh up to thousands of tons.

Till or glacial till is unsorted glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines.

Glacial till is usually a very hard and compact soil containing boulders, gravel, sand, silt, and clay-sized particles. Unless such dumped material has been very carefully compacted, it may be in a very loose state and therefore not a suitable soil for building upon.

Great for farming, (best nutrient capacity) but unstable but unstable in slopes or foundations!

At a terminal moraine, all the debris that was scooped up and pushed to the front of the glacier is deposited as a large clump of rocks, soil, and sediment. Scientists study terminal moraines to see where the glacier flowed and how quickly it moved.

Most eskers are argued to have formed within ice-walled tunnels by streams that flowed within and under glaciers. They tended to form around the time of the glacial maximum, when the glacier was slow and sluggish. After the retaining ice walls melted away, stream deposits remained as long winding ridges.

A large amount of snow that stays around all year is called a snowfield. If they grow large enough, the snow will pack together into ice and begin to flow like a glacier. A glacier is a large amount of ice that sits on the land.

The movie The Day After Tomorrow is loosely based on the theory of “abrupt climate change.” The plot of the movie is that, as a result of global warming, ocean currents that circulate water around the world shut down, heating up the tropics and cooling the North Atlantic.
