Final answer:
The thickness of the ice affects the temperature at the base of a glacier.
Step-by-step explanation:
The statement is true.
The thickness of the ice is indeed one of the factors that affects the temperature at the base of a glacier. The thick ice insulates the base of the glacier, preventing the transfer of heat from the underlying bedrock. This helps to maintain a lower temperature at the base.
For example, in a thicker glacier, there is a larger distance between the surface and the base, which allows for greater insulation and a lower temperature at the base.
