Glaciers

3. action / A function of hydrogen bonding in the water molecule results in the movement of water into small openings due to the attraction between the liquid and the walls of the opening. Water can be drawn upwards by capillary action.
5. Trough / Steep U-shaped valley with a flat bottom caused by glacial scour and erosion.
7. age / Reoccuring periods in Earth history when the climate was colder and glaciers expanded to cover larger areas of the Earth's surface. iers.
8. / Unsorted till (diamicton) deposited either along the sides (lateral moraine) or the ends of an ablating glacier (end or terminal moraine); or the material below a retreating glacier (ground moraine).

1. / The loss of ice from a glacier due to surface melting, evaporation and the calving of iceberg
2. / Ice sheets calve by breaking off flat pieces when the walls of crevasses give way or chunks fall off the front of an ice sheet. The results are called ice bergs, bergy bits and crevasse wall breakaways.
4. / The wearing away of rocks by the action of water, ice or wind using moving debris.
5. (glaciation) / (1) Period of time during an ice age when glaciers advance because of colder temperatures. (2) Involving glaciers and moving ice. Usually pertaining to processes associated with glac
6. / A steep armchair shaped hollow formed by the erosion of the rock by snow and ice. The rotational movement of the ice within the cirque hollows out the base creating a depression. The hollow will become a tarn once the ice retreats.
9. / Wind, water, and movement of glaciers remove material from (erode) the surface of the earth.
