Detailed explanation-1: -Glaciers melt when ice melts more quickly than firn can accumulate. Because they are so large, melting ice sheets can affect the climate of ecosystems in the entire world. Melting ice sheets contribute to rising sea levels.
Detailed explanation-2: -A glacier’s weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
Detailed explanation-3: -Ultimately, as the ice sheets shrink, the water they add to the ocean raises sea level around the world (see the Sea Level indicator).
Detailed explanation-4: -Numerous physical factors contribute to the rate of glacial movement including lithology, altitude, gravity/gradient slope, ice temperatures, ice thickness (size and mass), and mass balance. Basal slip and internal deformation are the two types of glacial movement.
