Question

How can glaciers
glaciers cause weathering?

Answer 1

Over time, they break apart due to rain.

Step-by-step explanation:

A lot of rain contains acid, so when the rain hits glaciers, it starts to decay.

Answer 2

As glaciers flow, mechanical weathering loosens rock on the valley walls, which falls as debris on the glacier. Glaciers can carry rocks of any size, from giant boulders to silt. These rocks can be carried for many miles over many years and decades. These unsorted deposits of rock are called glacial till.
