Greenland’s landscape is a dramatic mix of **vast ice sheets, rugged mountains, deep fjords, and sparse tundra**, shaped by millions of years of glaciation and Arctic conditions. Here’s a breakdown of its key features:
*1. The Greenland Ice Sheet (Inlandis)*
*Covers ~80% of Greenland* (1.7 million km²), second only to Antarctica.
*Average thickness: ~2,000 m* (up to *3,000 m* in some areas).
Contains **8% of Earth’s freshwater**—if melted, global sea levels would rise **7.4 meters**.
*Glaciers & Ice Streams* (like Jakobshavn/Ilulissat) drain ice into the ocean, calving massive icebergs.
*2. Ice-Free Coastal Regions*
Only *15-20% of Greenland* is ice-free, mostly along the coasts:
*Rocky Mountains & Cliffs**: The **Watkins Range* in the east has Greenland’s highest peak (**Gunnbjørn Fjeld, 3,694 m**).
**Fjords**: Deep, glacier-carved fjords (e.g., **Scoresby Sund**, the world’s largest fjord system).
**Tundra**: Low-lying areas have **Arctic grasses, mosses, and dwarf shrubs**—supporting muskoxen, Arctic hares, and reindeer.
*3. Permafrost & Arctic Deserts*
*Continuous permafrost* underlies most ice-free land.
*Polar deserts* exist in the north (e.g., **Peary Land**), with little precipitation and extreme cold.
*4. Volcanic & Geothermal Activity*
Greenland has *ancient volcanic rocks* (like the *Tertiary flood basalts* of Disko Island).
*Hot springs* (e.g., **Uunartoq**) exist due to geothermal activity.
*5. Climate Impact on the Landscape*
**Melting Ice Sheet**: Since the 1990s, Greenland has lost **~4,700 gigatons of ice**, reshaping coastlines.
*Expanding Vegetation**: Satellite data shows **greening* in southern Greenland as temperatures rise.
*Wildlife & Human Presence*
**Animals**: Polar bears, walruses, Arctic foxes, and migratory birds.
**Settlements**: Most towns (like **Nuuk, Ilulissat**) cling to the ice-free coast; the interior is uninhabited.
