Question

the formation of glaciers,a natural or human-made change.​

Answer 1

Forming of glaciers is a natural change reason as :-

A glacier forms when snow accumulates over time, turns to ice, and begins to flow outwards and downwards under the pressure of its own weight. In polar and high-altitude alpine regions, glaciers generally accumulate more snow in the winter than they lose in the summer from melting, evaporation, or calving.
