It makes erosion easier for the glacier and why?

Glaciers erode the landscape through a process called glacial erosion, which occurs as the glacier moves over rock and soil. The immense weight of the ice creates pressure, causing the underlying material to fracture and break apart. Additionally, meltwater from the glacier can infiltrate cracks, further facilitating erosion by freezing and expanding, which dislodges more material. This combination of mechanical and hydraulic forces makes erosion easier and more effective as the glacier advances.
