Question

ablation is the removal of ice from a glacier and includes multiple processes: sublimation, melting, and calving. label where each of these is occurring in the helheim glacier image.

Answer 1

Sublimation occurs when ice and snow change directly to water vapor without first melting to form liquid water. Melting occurs when ice is heated and changes from a solid state to a liquid state. Calving refers to the process of large chunks of ice breaking off from a glacier and falling into the water.

Step-by-step explanation:

Sublimation:

Sublimation occurs when ice and snow change directly to water vapor without first melting to form liquid water. This process happens due to the heat from the sun.

Melting:

Melting occurs when ice is heated and changes from a solid state to a liquid state. This process is happening in areas where the temperature is warm enough to cause the ice to melt.

Calving:

Calving refers to the process of large chunks of ice breaking off from a glacier and falling into the water. This typically occurs at the edge of the glacier where it meets the ocean or a body of water.
