How does a glacier cause weathering and erosion?

Answer:
Glaciers are huge chunks of snow and ice most time more than 1000 feet thick. They weigh huge amount and overtime become so condensed that they are harder than the rock they are on top of. They move at slow rates and the ice and erodes the rock into a fine powder that is then left behind. They erode the rock over hundreds of years and create huge valleys
