Cold, indeed somewhat icy. Must be moving for it to be a glacier. (Non moving form is an ice sheet). must be permanent and more than 1 sq mi in area.
Valleys, mountains,canyon's, and hilly areas are all made by glaciers. One of the most outstanding is Yosemite National Park. The entire park was created by a glacier and it is wonderful.
A glacier moves as solid, not a liquid, so movement is slow. Their movement is dependent upon accumulation and wastage.

Glaciers played a significant role in shaping Minnesota's landscape by creating its lakes, rivers, and rolling hills. They also deposited rich layers of soil, making the state fertile for agriculture. Glacial retreat left behind distinct features like kettle lakes and moraines that contribute to the state's unique geography.
Glacial striations, erratic boulders, drumlins, and moraines are some geological evidence found in Alberta indicating past glaciation. These features were left behind by moving glaciers and are common throughout the province, especially in the Canadian Rockies and foothills regions.
Cirques are bowl-like features cut into mountains or hills where glaciers form. They are typically found at high elevations and are formed by the erosive action of glaciers carving out the landscape.
Glaciers shaped the Canadian landscape by sculpting valleys and creating lakes through erosion and deposition of sediment. They also left behind large deposits of till and moraines, contributing to the diverse topography of Canada. Melting glaciers have continued to impact the landscape by forming iconic features such as the Great Lakes and Niagara Falls.
