Scientists uncover secrets and techniques beneath Greenland’s ice, revealing a once-thriving ecosystem with valleys, rivers, and lakes.
Greenland’s ice sheet, practically 2 miles thick, covers 80% of the island and is melting at a fee of over 200 billion tons per 12 months.
A newly found subglacial canyon, over 460 miles lengthy and a couple of,600 ft deep, is the longest canyon on Earth, buried beneath ice.
Geological surveys point out Greenland’s bedrock incorporates uncommon earth components and valuable metals, essential for contemporary know-how.
The Hiawatha crater, a 19-mile huge affect website from an asteroid strike 58 million years in the past, lies beneath 3,000 ft of ice.
Greenland’s glaciers are influenced by hidden mountain ranges and submerged fjords, affecting their motion and melting charges.
As temperatures rise, Greenland’s distinctive geological options could result in the unfold of vegetation, probably reworking its panorama.
