| 1. | Deep erosion, possibly by a continental ice sheet, happened during this time.
|
| 2. | Shaped by continental ice sheets and significant sea-level changes helped create the climate.
|
| 3. | Continental ice sheets have repeatedly advanced and retreated from the Puget Sound region.
|
| 4. | The coalesced continental ice sheet traveled south terminating in the vicinity of Chehalis, Washington.
|
| 5. | As the continental ice sheet moved in from the north, it pushed moraine forward.
|
| 6. | The Transantarctic Mountains bisect the continental ice sheets, with different ice flow dynamics on either side.
|
| 7. | These chilly lakes among mountain peaks were separated from the continental ice sheet to the north.
|
| 8. | The mass of ice from the continental ice sheets had depressed the rock beneath it over millennia.
|
| 9. | Antarctica is home to more than 70 lakes that lie at the base of the continental ice sheet.
|
| 10. | Starting at the last glacial maximum, 21, 000 years ago, continental ice sheets retreated and sea levels rose.
