  1. 2. a long, narrow strip of sea that falls between tall cliffs
  2. 4. till a jumble of unsorted and unlayered sediment (like clay, sand, gravel, and boulders) deposited directly by glacial ice as it moves or melts, rather than being sorted by water
  3. 9. long, cylindrical samples drilled from glaciers and ice sheets, acting as Earth's climate archives, trapping layers of snow that, when compressed, preserve ancient atmospheric gases, dust, and volcanic ash
  4. 10. a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.
  5. 12. a massive, perennial river of ice, snow, rock, and sediment that forms on land and slowly moves downhill due to gravity
  6. 13. fossil used to determine the relative age of a given rock
  7. 14. distinct ridges or mounds of debris that are laid down directly by a glacier or pushed up by it
Down
  1. 1. the preserved remains, impression, or trace of a living thing from a past geological age, like bones, shells, leaves, or even footprints, that has been preserved in rock or other natural materials, giving clues about ancient life
  2. 2. the total collection of all fossils discovered (preserved remains or traces of ancient organisms) and their placement in the Earth's crust, arranged chronologically in sedimentary rock layers
  3. 3. The gravitational force exerted on an object by a planet or moon
  4. 5. the long-term average of weather patterns in a region, describing the typical conditions (like temperature, rainfall, humidity) expected over many years, usually 30 or more, rather than what's happening on a specific day
  5. 6. Earth's continuous process of circulating water above, on, and below its surface, involving phase changes (liquid, vapor, ice) through key stages like evaporation, condensation, precipitation, and collection/runoff, powered by the sun's energy, ensuring water's constant recycling.
  6. 7. when a type of living thing (like a species of animal or plant) completely dies out and no longer exists anywhere on Earth
  7. 8. the invisible force that pulls objects with mass toward each other
  8. 9. a period in Earth's history when the ice on the polar caps significantly expands due to a lowering of the Earth's global temperatures
  9. 11. a glacier that forms high in mountains, confined by terrain, flowing downhill through valleys and sculpting the landscape into features like U-shaped valleys, often starting in bowl-shaped depressions called cirques
