Step 1
Chosen processes: Plucking and Abrasion
Answer
The processes involved in shaping the landscape are Plucking and Abrasion. Plucking occurs when meltwater seeps into the cracks and crevices of rocks. As the ice melts and refreezes, the meltwater can freeze again, forming a bond with the rocks. When the ice sheet begins to move again, it plucks pieces of rock away from the ground and carries them along the bottom of the ice sheet.
Abrasion, on the other hand, happens when the ice sheet moves and drags the rocks that have been plucked from the ground. This action is akin to a sandpaper effect on the land, as the ice scrapes away more rock, carving out valleys and hollows. The landscape created by these two processes can be seen in features like corries, which are evident on the map. For instance, the large tarn lakes present indicate significant glacial activity.
These processes lead to the formation of distinct landforms, which can be outlined on the map provided.
