ice sheets

Ice sheets are massive, thick layers of ice that cover vast areas of land, primarily found in Antarctica and Greenland. They form from accumulated snow that compacts over time. Ice sheets play a crucial role in Earth's climate and sea levels; when they melt, they contribute to rising ocean levels. These ice formations can be several kilometers thick and are important indicators of climate change, as their size and stability reflect long-term environmental conditions. Monitoring ice sheets helps scientists understand global warming and predict future impacts on weather patterns and coastal communities.
