Across
- 2. unsorted material deposited directly by glacial ice and showing no stratification. It is sometimes called boulder clay because it is composed of clay, boulders of intermediate sizes, or a mixture of these.
- 6. a steep-sided mound of sand and gravel deposited by a melting ice sheet.
- 8. pointed peaks that are bounded on at least three sides by glaciers
- 9. ridges made of sands and gravels, deposited by glacial meltwater flowing through tunnels within and underneath glaciers, or through meltwater channels on top of glaciers
- 10. a low oval mound or small hill, typically one of a group, consisting of compacted boulder clay molded by past glacial action
- 11. a deep open crack, especially one in a glacier.
- 13. an amphitheatre-like valley formed by glacial erosion
Down
- 1. occurs at the base of the glacier as the ice drags along an uneven surface. The weight and moving force of the ice will break the bedrock and incorporate the fragments into the glacier
- 3. a loosely compacted yellowish-gray deposit of windblown sediment of which extensive deposits occur, e.g., in eastern China and the American Midwest.
- 4. happens when the glacier, after plucking up rocks from the ground, uses the rocks stuck beneath it to scrape and grind against the surface of the earth
- 5. a long, narrow, deep inlet of the sea between high cliffs, as in Norway and Iceland, typically formed by submergence of a glaciated valley
- 7. These form when a block of stagnant ice (a serac) detaches from the glacier
- 12. temporary or short-term
