توازن مرتد

التوازن المرتد Post-glacial rebound ، هو ارتفاع جزء من القشرة الأرضية، نتيجة إزالة وزن كبير مثل جليد المثالج.

A model of present-day mass change due to post-glacial rebound and the reloading of the ocean basins with seawater. Blue and purple areas indicate rising due to the removal of the ice sheets. Yellow and red areas indicate falling as mantle material moved away from these areas in order to supply the rising areas, and because of the collapse of the forebulges around the ice sheets.
