Summary
A new map of Antarctica reveals its hidden landscapes under the ice, including mountains and valleys. This map helps scientists understand more about the continent's hidden features and supports better predictions of ice movement and sea level changes.
Key Facts
- Scientists have made a detailed map showing Antarctica's terrain under the ice.
- This map reveals previously unknown mountains, canyons, and valleys.
- The Antarctic Ice Sheet contains about 70% of the Earth's freshwater.
- They used a method called Ice Flow Perturbation Analysis, along with satellite data, to map the landscape.
- Knowing what's under the ice helps scientists predict how the ice will move and affect sea levels.
- Antarctica's land surface is less understood than Mars' surface, even though Mars is much farther away.
- Previous research shows that rough terrain under the ice can slow down its movement.
