Are bedrock channels more likely to be found near the head or near the mouth of a stream?
In their headwaters, where the gradient is steep, most rivers cut into bedrock. These streams typically transport course particles that actively abrade the bedrock channel.
Which cross section best represents the valley shape where a rapidly flowing stream is cutting into the bedrock in mountains area?
v-shaped mountains
How is a stream created?
A stream is formed form water flowing downhill from the highest point of a mountain or a hill. (From Yahoo Answers)
Where is the stream eroding the bank?
Stream Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from erosion of the bed of the watercourse, which is referred to as scour. The roots of trees growing by a stream are undercut by such erosion. As the roots bind the soil tightly, they form abutments which jut out over the water. These have a significant effect upon the rate and progress of the erosion.
Why is a resurgent stream only formed in a limestone area?
A resurgent stream is formed when an underground river is forced to reappear when it reaches a layer of impermeable bedrock. For a river to become an underground river in the first place it must flow over an area of limestone rock. The mildly acidified river water (it is acidified by dissolved carbon dioxide which is present in rainwater) reacts with the limestone (which is 80% calcium carbonate) and dissolves it. This forms a swallow hole into which the river flows. The river then continues to chemically weather the limestone underground thus forming an underground river. The river is forced to reappear (in the form of a resurgent stream) on the surface when there is a change of rock type from permeable limestone to impermeable bedrock. Hence resurgent streams are typically only found in limestone areas.
