Across
- 2. -A warmer period between two glacial periods within an ice age, such as the current Holocene epoch.
- 7. till -an unsorted and unstratified mixture of clay, silt, sand, gravel, and boulders deposited directly by a glacier
- 8. -A large, persistent body of dense ice and snow that forms on land and moves under the force of gravity.
- 10. ages -
- 11. core -cylinder of ice drilled from glaciers or ice sheets, acting as a frozen time capsule that reveals Earth's past climate and atmosphere
- 14. -The process by which glaciers, wind, or water transport sediment, altering the Earth's surface and creating distinct landforms.
- 15. stones -Rocks dropped by icebergs into fine sediment.
Down
- 1. periods -a long, cold phase within an "ice age" when large ice sheets expand from the poles,
- 3. glacier - a massive block of ice that floats through land
- 4. -a landform made of till, or un-sorted and un-stratified debris like rocks, sand, and soil, that is left behind by a retreating glacier.
- 5. cycle -Earth's continuous process of recycling and moving water between the atmosphere, land, and oceans, involving stages like evaporation, condensation, precipitation, and collection, where water changes states (liquid, vapor, ice) to sustain life
- 6. -The unsorted sediment (sand, gravel, boulders, and fine powder called rock flour) left behind by retreating or melting glaciers.
- 9. glacier - a glacier that falls down off of mountains and makes a glacier on the mountain hills
- 12. forms -Glacial valleys, moraines, and U-shaped valleys show past ice extent.
- 13. -a long and narrow mountain valley with water in it
