13. What causes the long-term trend of rising bedrock near glaciers? Seasonal changes with the ground freezing in the winter (causing the ground to rise) and the ground thawing in the summer (causing the ground to lower) Seasonal changes with snow melting in the summer (causing the ground to rise) and snow accumulating in the winter (causing the ground to lower) The climate is getting warming, so the ground is expanding due to the extra heat, causing the ground to rise. The glacier is melting and getting smaller, so it weighs down less on the ground, causing the ground to rise. 1 poin
