Sierra Nevada mountain has about 800 little mountain glaciers as well as perennial ice fields. The larger volumes of ice on steeper slopes move more quickly than the ice on the more gentle slopes farther down the valley. A glacier typically moves slowly on the order of a few tens of meters.

California is one of the places in USA where there is evidence of Pleistocene glaciations. As a glacier moves downhill it loses more and more ice by melting and sublimation. Describe how glaciers move the rate at which they move and the significance of the glacial budget.

The direction of movement of a glacier is best indicated by the. Which of the following best describes the movement of a glacier. A valley glacier spreads out over a large island or continent.

The center of a glacier moves more rapidly than the sides and the surface more rapidly than the bottom because the sides and bottom are held back by friction. At the bottom of the glacier ice can slide over bedrock or shear subglacial sediments. Which of the following is evidence that an area was once covered by a glacier.
