Glaciers form in areas where the summers are not warm enough to melt snow. The snow gradually piles up over many years and the weight of all that snow compacts the snow layers below it into solid ice.
The movement of glacial ice is called glaciation or glacial flow. Glaciers move due to the force of gravity and the deformation of the ice under pressure. This movement can result in the formation of features like moraines, crevasses, and glacial valleys.
Pertaining to ice or to its action; consisting of ice; frozen; icy; esp., pertaining to glaciers; as, glacial phenomena., Resembling ice; having the appearance and consistency of ice; -- said of certain solid compounds; as, glacial phosphoric or acetic acids.
A kettle is a depression left by melted blocks of ice in glacial deposits.

Glacial ice is much more solid then regular ice. Glacial ice is also alot colder than regular ice. Glacial ice can also be up to 1/2 a mile thick. Glaciation is aan extremly powerful force. 2. Glaciation happend very recently in geologic terms and there has not been enough time for the glacial features to be worn away.
Glacial periods refer to times of extensive ice coverage on Earth, while interglacial periods are warmer intervals between glacial periods when the ice retreats. Glacial periods typically involve lower global temperatures and ice sheet expansion, while interglacial periods are characterized by higher temperatures and diminished ice coverage.
Two types of glacial deposits are moraines, which are formations of mixed sediment pushed by and deposited from a glacier, and drumlins, which are elongated hills made of glacial till that form parallel to the direction of ice flow.
Yes, glacial ice is formed over a long period by the accumulation and compaction of snow, which results in a denser and clearer ice compared to regular ice formed in water bodies. Additionally, glacial ice may contain air bubbles, dust, and other particles trapped during the freezing process, giving it a distinctive appearance.

A glacial system is a complex combination of glaciers, ice sheets, ice caps, and icebergs. It involves the movement of ice and snow, as well as the processes of accumulation and ablation of ice. Glacial systems play a crucial role in shaping the Earth's landscape and influencing global climate patterns.
Glacial ice is almost 100% fresh water. When the ice melts, the fresh water pours into the oceans, making the salinity go down.
The unsorted rock material deposited by ice when it melts is called glacial till. Glacial till can vary in size from clay to boulders and is typically a mixture of rock types that were picked up and carried by the moving glacier.
