Glaciers and ice caps are large masses of ice that form from accumulated snow over many years. They are found in polar regions and high mountains, where temperatures are low enough to prevent the snow from melting completely. Glaciers flow slowly under their own weight, while ice caps cover extensive areas, often blanketing entire landmasses. These ice formations play a crucial role in Earth's climate system. They store about 70% of the planet's fresh water and help regulate sea levels. As global temperatures rise, glaciers and ice caps are melting at an alarming rate, contributing to rising ocean levels and impacting ecosystems worldwide.
