Glacial Ice Is Actually Rock.

Glacial ice is actually classified as metamorphic rock! When individual snowflakes fall and are pressed together on the ground, pressure eventually transforms them into larger and denser ice crystals through a process called metamorphosis. Essentially, snow is turned into a solid field of ice. And because glacial ice goes through a process of changing from one solid form (snowflakes) to another (ice crystals), it is considered metamorphic rock.
