What is the characteristic feature of the accumulation of snow and ice on valley glaciers?

• It rarely exceeds 10 m in thickness

• It is thickest at the center

• It exceeds 40 m in thickness

• It is uniform across the glacier

What are the cracks in the glacier called?

What causes both valley and continental glaciers to recede?

• When the snowfall exceeds the melting rate

• When the glacier reaches sea level
