Glaciers

4. The loss of glacier ice through melting, sublimation, or calving
7. Long‑term shifts in global or regional climate patterns, often linked to human activity
9. The process or period during which land becomes covered by glaciers or ice sheets
10. The world’s largest island, mostly blanketed by an ice sheet and numerous outlet glaciers
12. The breaking off of ice chunks from a glacier’s edge, usually forming icebergs
13. A group of large freshwater lakes in North America carved and deepened by past glaciation
15. Accumulations of rock and soil deposited by a glacier, often marking its former limits

1. The wearing away and reshaping of Earth’s surface by water, wind, ice, or gravity
2. Grooves or scratches ground into bedrock by rocks at a glacier’s base, indicating ice movement
3. Vast ice sheets covering extensive land areas, such as those in Antarctica and Greenland
5. Glaciers that form in mountainous regions and flow downhill through valleys
6. A period in Earth’s history characterized by lower global temperatures and widespread glaciation
8. Streamlined hills shaped beneath moving ice, with their tapered end pointing in flow direction
11. The southernmost continent, predominantly covered by a massive ice sheet and many glaciers
13. Large bodies of ice formed from compacted snow that move slowly under their own weight
14. Floating masses of ice that have fractured away from glaciers or ice shelves
