GEOLOGY

Detailed explanation-1: -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 may vary in width from a few centimeters to several tens of kilometers.

Detailed explanation-2: -streambed, also called Stream Channel, any long, narrow, sloping depression on land that is shaped by flowing water. Streambeds can range in width from a few feet for a brook to several thousand for the largest rivers. The channel may or may not contain flowing water at any time; some carry water only occasionally.

Detailed explanation-3: -Main channel means a channel that has flowing water when average flows occur.

Detailed explanation-4: -Formation of Stream Channels A stream channel can form as the result of surface or subsurface processes, or some combination of the two. Heterogeneities in the surface and subsurface properties of hillslopes create zones of preferential flow during downslope movement of water.

Detailed explanation-5: -A channel is a wide strait or waterway between two landmasses that lie close to each other. A channel can also be the deepest part of a waterway, or a narrow body of water that connects two larger bodies of water.
