What makes the Perito Moreno Glacier one of the few glaciers in the world that remains in dynamic equilibrium?
Answer and explanation
Correct answer: A. It advances periodically across Lake Argentino to dam the Brazo Rico and Canal de los Témpanos
- Step 1: The glacier descends from the ice field to form a 5-kilometer-wide wall 70 meters high. Step 2. When it reaches the Magallanes Peninsula, it forms a natural ice dam across the lake. Answer: It advances periodically across Lake Argentino to dam the Brazo Rico and Canal de los Témpanos. Why not the others: Water pressure eventually breaks the ice dam in a spectacular natural rupture.
