Glacial Striations • Rocks scrape the underlying bedrock • This picture was taken near Squamish 1997 CL. This flux is, in long-term, dictated by snow input, hence erosion would tend to increase with amount of snow, S (E~10-3 S) Quarrying rates are high for glaciers that: - move rapidly (sliding ≥100 m/yr) Draw a sketch of the river bed, label: terminal morraine, lateral moraine, bedrock, outwash plain, and alluvial fan. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. Glacial erosion includes processes that occur directly in association with the movement of glacial ice over its bed, such as abrasion, quarrying, and physical and chemical erosion by subglacial meltwater, as well as from the fluvial and mass wasting processes that are enhanced or modified by glaciation. When the ice is present, they form stark, rocky outcrops above it, adding to the beauty of these harsh landscapes. When a piece of a glacier breaks off and floats in the water, it's called an iceberg. There are two main types of glaciers.
