How Did Antarctica Freeze?
The prime suspect is a gradual reduction of CO2 in the atmosphere, combined with a ‘trigger’ time when Earth’s orbit around the sun made Antarctic summers cold enough for ice to remain frozen all year round.
How did Antarctica get covered in ice?
The glaciers carved out valleys that had already been worn in by river flow, changing the topography. Once the expansive ice sheets that now cover the continent began to form, they preserved these landforms in frigid perpetuity.
