Antarctic Lava to Pink Snow: The Science of Winter

The video explores how insects survive winter, the unique lava lake at Mount Erebus, the various forms of ice, and the phenomenon of watermelon snow. Insects adapt to cold by migrating, entering diapause, or dying off. Mount Erebus in Antarctica hosts a rare lava lake with unique gas emissions. Ice has many forms due to water's unique chemistry, with some forms existing only in space. Watermelon snow is caused by algae that turn snow pink, thriving in high altitudes.
