Study Notes
Ice Sheets
- Massive expanses of glacial ice that cover large portions of land, primarily in polar regions
- Form over thousands of years as snow accumulates and compresses into ice
- Become thick enough to flow under their own weight after thousands of years of accumulation
Types of Ice Sheets
- Two main ice sheets on Earth: Antarctic Ice Sheet and Greenland Ice Sheet
Roles of Ice Sheets
- Regulate Earth's climate
- Influence ocean circulation patterns
- Serve as a record of past climate conditions with layers of ice preserving information about atmospheric composition and temperature over thousands of years
Vulnerability of Ice Sheets
- Highly vulnerable to climate change
- Melting contributes to sea level rise, posing risks to coastal communities and ecosystems worldwide
