Item WE011002: Ice that freezes in the cracks of the solid rock layer, and glaciers that move against the solid rock layer, can change the surface of the earth by breaking the solid rock layer.
How can ice change the surface of earth’s outer solid rock layer?
- Ice breaks off pieces of rock when glaciers move against earth's solid rock layer and also when water freezes in cracks in the solid rock layer.
- Ice breaks off pieces of rock when glaciers move against earth's solid rock layer, but not when water freezes in cracks in the solid rock layer.
- Ice breaks off pieces of rock when water freezes in cracks in earth's solid rock layer, but not when glaciers move against the solid rock layer.
- Ice cannot change the surface of earth's outer solid rock layer.
