describe the water cycle
plants release water into the atmosphere through a process called
balance in the water cycle means that
the ability of a stream to erode and transport material depends largely on its
the single most important erosion agent on earth is
along a straight streches of a stream channel, the highest velocities of water are found in what part of the stream
if you were to examine the profile of a typical stream, you would probably find that the gradient is
base level is
what is the ultimate base level of a stream
most streams carry the largest part of their load
describe the suspended load of a stream
a depositional feature that forms where a stream enters a lake or ocean is a(n)
a natural lavee is
in a stream channel what will be deposited first
the flat portion of a valley floor adjacent to a stream channel is called a
the most prominent features of a narrow V-shaped valley where the stream profile drops rapidly are
what type of stream valley would form in a mountainous area
a drainage basin is
groundwater is found underground in the zone of
permeable rock layers or sediments that transmit groundwater freely are called
the percentage of the total volume of rock or sediment that consist of pore spaces is called
what is the measure of a materials ability to transmit fluids through interconnected pore spaces
when groundwater enters underground fractures or caverns in hot igneous rocks where it is heated to boiling temperatures what feature can form
what are major sources of groundwater pollution
describe stalactites
sinkholes can form when
what features are associated with karst topography
the average annual precipitation worldwide must egual the quantity of water
describe a streams discharge
what features are found in a wide valley
one major cause of floods is
one traditional flood control method has been to attempt to keep the streams flow within its channel by creating
describe the zone of saturation
any formation in which groundwater rises on its own under pressure is a(n)
caverns most commonly form in what type of bedrock
how is the water cycle balanced
what type of valley is characterized by waterfalls, rapids, and a stream that is primarily eroding downwards
what river has the largest drainage basin in north anerica
