Which of these is an example of an atmosphere-cryosphere interaction?

A.

snow falling on a glacier

B.

the wind dispersing tree seeds

C.

air molecules escaping into space

D.

icebergs breaking off an ice sheet

This would be snow falling on a glacier since the cryosphere has to do with frozen water on the surface of earth (AKA Glaciers) and the snow comes from the atmosphere. So we can say that snow and glaciers make an atmosphere-cryoshere interaction.
