Key Concepts: Glacial Erosion, Plucking, Abrasion, Meltwater, Freeze-Thaw Weathering, and Glacial Scenery.

Glacial erosion is like a massive bulldozer powered by nature. The strength of erosion hinges on several factors such as the local geology, speed of the glacier, the heaviness and thickness of the ice, plus the amount and nature of the load carried.

Real-World Example: Consider a super strong weightlifter (the glacier) trying to push a pile of sandbags (the local geology). How far and how quickly they can push the pile depends on their strength (the thickness of the ice), their energy level (velocity of the glacier), and how heavy or bulky the sandbags are (the load carried).

Plucking mostly occurs at the base and sides of a glacier. Here, ice meltwater seeps into the joints and freezes to the rock, which is then yanked out by the moving glacier. This process is most effective in jointed rocks or rocks that have been weakened by freeze-thaw cycles. Plucking involves downward pressure due to the weight of the ice and its downhill movement. After being plucked, these materials can then be used for abrasion.

Real-World Example: Picture plucking like pulling weeds from a garden. The ice (gardener) seeps into the joints (root system) and then yanks out the rock (weed). The rock, like the weed, is plucked from its spot, ready to be tossed elsewhere (like abrasion)!
