Mysterious “Spiders” Emerge On Mars During Springtime (Here’s Why)

As springtime sunshine bathes the Martian floor, it begins to heat the layers of CO2 ice deposited throughout the lengthy, darkish winter. This triggers a course of known as sublimation, the place the stable ice transforms instantly into fuel with out transitioning to a liquid state. Trapped beneath layers of overlying ice, this carbon dioxide fuel builds up stress, ultimately reaching a degree the place it bursts via the frozen floor – very similar to a geyser on Earth.
