Answer:
Hydrosphere
Step-by-step explanation:
All the glacial ice present on earth belongs to the hydrosphere. Hydrosphere represents all the water bodies (ice, vapor, and liquid) existing on earth.
Glaciers are the region where the temperature is low and continuous accumulation of snow takes place in consecutive years. In due course of time, these accumulated snow undergoes compaction as a result of which it subsequently forms ice.
The factors that are responsible for the formation of snow re s follows-
1) Areas of high latitude
2) Low temperature
3) Presence of abundant snow
4) Snow accumulation must be more.
