Across
- 4. lakes long, narrow lakes found in glaciated valleys formed in locations where the glacier had more erosive power, e.g. in areas of softer rock, where the valley gradient temporarily steepened or a tributary glacier joined the main valley.
- 5. Sheet huge mass of ice covering the landscape that moves very slowly. Only the mountain peaks protrude above the ice.
- 7. Rock a rock with sharp edges.
- 8. sharp, knife-like ridge formed between two cirques cutting back.
- 10. Valley a river valley widened and deepened by the action of glaciers (ice sheets); they become ‘U’-shaped instead of the normal ‘V’-shape of a river valley.
- 11. the wearing away of the land by rivers, ice sheets, waves and wind.
Down
- 1. a deep circular lake filling a cirque hollow.
- 2. armchair-shaped hollow in the mountainside formed by glacial erosion and freeze-thaw weathering. This is where the valley glacier begins.
- 3. a slope of loose, large angular rocks broken away from the mountainside by freeze-thaw weathering.
- 6. Spur a former river valley spur which has been sliced off by a valley glacier.
- 8. erosion caused by rocks and boulders in the base of the glacier acting like a giant file scratching and scraping the rocks below.
- 9. Moraine a prominent ridge of rock debris dumped at the end of a glacier and formed of unsorted boulders, sand, gravel and clay.
