What exactly is a glacier?

What exactly is a glacier? Is it rock 🪨or just ice?🧊 They are, after all, both rock and ice! Glaciers are long-term accumulations of crystalline #ice, snow, rock, and, in certain cases, liquid water that begin on land. They covered one-third of the Earth's surface during the previous Ice Age and currently cover just around 10% of the Earth's surface. Glacier is not only a magnificent natural wonder, but also a haven for adventure seekers. 1.
