    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
