Glacial flow refers to the movement of glaciers due to the deformation and sliding of ice.

Valley glaciers are long, narrow glaciers that flow through valleys, often originating from ice fields or ice caps.

Glacial abrasion occurs when glaciers slide over bedrock, scraping and grinding the surface, resulting in the erosion and transport of rock and sediment.

Moraines are ridges or mounds of sediment deposited by glaciers, typically found at the edges or termini of glaciers.

Confluence glaciers are formed when two or more glaciers merge together, resulting in a larger glacier with a wider flow path.

Glacial calving occurs when large pieces of ice break off from the terminus of a glacier and fall into the ocean.

Ice sheets are large, dome-shaped glaciers that cover vast areas of land, typically found in polar regions.

Glacial retreat refers to the process by which glaciers lose mass and shrink in size, typically due to changes in climate or environmental conditions.

Piedmont glaciers are relatively flat, expansive glaciers that flow outward from a central point, often forming at the base of mountain ranges.

Glacial advance refers to the process by which glaciers gain mass and grow in size, typically due to changes in climate or environmental conditions.

Valley glaciers are relatively small glaciers that flow through high-altitude mountain valleys, often originating from ice fields or ice caps.

Glacial surge refers to the process by which glaciers experience a sudden increase in flow velocity, often resulting in rapid movement and changes in glacier shape.

Mountain glaciers are relatively small glaciers that cover the summit and upper slopes of mountains, often found in high-altitude regions.

Glacial accumulation refers to the process by which glaciers form and accumulate ice through snowfall, avalanches, and other processes.

Alpine glaciers are relatively small glaciers that flow through steep, narrow mountain valleys, often found in high-altitude regions.
