| alpine glacier | a glacier that forms in mountainous areas |
| continental glacier | continuous mass of ice, spreads across entire continents |
| ice shelf | attached to an ice sheet but is under water |
| iceberg | large pieces of ice formed by calving |
| crevasse | a large crack in the ice that forms where the ice picks up speed or flows over a high point |
| glacial drift | all material carried and deposited by glaciers |
| valley glacer | form in valleys by stream erosion, flow downward |
| till | a type of glacial drift that is deposited directly by the ice when it melts |
| cirque | a bowl like depression where glacial ice cuts back into the mountain walls |
| arete | jagged ridges formed by cirques cutting into the same mountain |
| horn | sharp pyramid shaped peaks that form when three or more cirques erode the mountain |
| ground moraine | unsorted material left beneath a glacier |
| terminal moraine | eroded rock material that is dropped at the front of a glacier |
| striations | glacial grooves in the surface rock |
| lateral moraine | deposits that form along the side of a glacier |
| outwash plain | streams that carry an abundance of sorted material which is left in broad area when the glacier retreats |
| kettle | sediments that build up around a block of ice, which later forms a depression which fills with water |
| hanging valley | small glacial valleys which jointhe deeper main valley, and form waterfalls after the ice is gone |
| U-shaped valley | formed by the downward movement widening and straightening the valley as it travels |
| glacier | enormous mass of moving ice |
