1. Size and Shape:
* Alpine glaciers: Relatively small, confined to mountain valleys. They are often shaped like rivers of ice, flowing down slopes.
* Continental glaciers: Vast, covering large land areas. They are typically dome-shaped or sheet-like, spreading outwards from a central area.
2. Formation:
* Alpine glaciers: Form from the accumulation of snow in high-altitude valleys.
* Continental glaciers: Form from the accumulation of snow over vast, flat areas, often at lower elevations than alpine glaciers.
3. Movement:
* Alpine glaciers: Flow primarily downhill due to gravity, carving U-shaped valleys and leaving behind moraines and other glacial features.
* Continental glaciers: Move outwards from a central point due to their immense weight, smoothing and eroding the landscape, leaving behind vast plains and other glacial features.
4. Impact on Landscape:
* Alpine glaciers: Create dramatic, mountainous landscapes with sharp peaks, U-shaped valleys, and glacial lakes.
* Continental glaciers: Sculpt vast, flat plains, carve out large lakes, and create fjords (deep, narrow inlets) along coastlines.
5. Current Status:
* Alpine glaciers: Generally smaller and more susceptible to climate change, with many experiencing rapid retreat.
* Continental glaciers: While also impacted by climate change, they are larger and have a slower response time, though their retreat can have major consequences for global sea levels.
