Glaciers & Ice Sheets
Understand how glaciers and ice sheets form and behave — snow accumulates over centuries and compresses into dense ice, glaciers flow slowly downhill under their own weight carving U-shaped valleys and depositing moraines; the Greenland and Antarctic ice sheets together hold enough ice to raise sea levels by over 65 metres; and ice cores drilled from these sheets contain trapped air bubbles that reveal Earth's climate history going back 800,000 years
Typical age: 9–11 years
“Can your child explain how glaciers form from layers of snow pressed into ice, how they slowly carve valleys, and that scientists drill into ice sheets to learn about Earth's climate thousands of years ago?”
