How does erosion and wearing away of a mountain affect the depth to which the crust extends into the asthenosphere?
What will be an ideal response?
Just as shaving off the top of an iceberg would lighten an iceberg and cause it to float higher, the erosion and wearing away of a mountain lightens it and causes it to float higher on the asthenosphere. In other words, the crust isostatically adjusts when it loses mass due to erosion.
