Ice caps are large areas of ice that cover land, primarily found in polar regions like Antarctica and Greenland. They form when snow accumulates over many years and compresses into ice. Ice caps play a crucial role in regulating the Earth's climate by reflecting sunlight and maintaining global temperatures. These ice formations are important freshwater reserves, as they store about 70% of the world's fresh water. However, due to climate change, many ice caps are melting at an alarming rate, contributing to rising sea levels and impacting ecosystems and human communities around the world.
