25
stream
any flow of water through a channel
26
water moves through what?
the hydrologic cycle
27
streams begin as what?
meltwater from glaciers, runoff from the land surface, or outflow from lakes or springs
28
the hydrologic cycle
water evaporates from the ocean and rises through the atmosphere, where it condenses to form clouds. the clouds release precipitation that may flow overland in streams, sink underground as groundwater, or be absorbed by plants.
29
base level
lowest point to which a river can flow
30
ultimate base level
the ocean
31
drainage basin
drained by a stream and its tributaries; separated by high ground
32
divide
separates a drainage basin by high ground
33
stream gradients
change in elevation of a stream over a given distance
34
when do stream gradients decrease?
downstream direction
35
stream channel
channel roughness
