Glaciers. Geologists define a glacier as any large mass of ice that moves slowly over land. There are two types of glaciers: Continental glaciers Valley.

A stream is a body of water that carries rock particles and dissolved ions and flows down slope along a clearly defined path, called a channel. Thus, streams.

More Stream Erosion Rivers __________ because the landscape is flat. Some Landscapes are flat because they are extremely ___________. Other Landscapes are flat for other reasons, like recent sediment _____________.

Rejuvenation of a stream _________ of Land (Lowering of Sea Level, sometimes greater stream flow) causes stream to speed up and cut deeper. Stream valley takes on youthful characteristics but retains features of older stages as well. Can happen at any point in the _______.
