Scientists Solve the Mystery of Why Antarctica Froze Before the Arctic
Antarctica’s first ice sheet may have begun with a geological head start hidden deep beneath the continent. Millions of years before thick ice spread across the Northern Hemisphere, forces inside Earth lifted East Antarctica into a vast region of mountains and plateaus. The higher terrain became cold enough to preserve snow even when the planet [...]
A new study published in the journal Science reveals that the formation of ice in Antarctica occurred due to geological processes that raised the terrain, allowing the region to become cold enough for ice formation, even during a period when global temperatures were higher. The research, led by Thomas Gernon, Professor of Earth Sciences at the University of Southampton, indicates that the first Antarctic ice sheet began forming approximately 34 …
A new study indicates that tectonic processes that began during the breakup of the supercontinent Gondwana may have played a decisive role in the formation of the ice sheet.
