______ are components of the hydrologic cycle that release water vapor directly to the atmosphere.
Evaporation and transpiration
______ is not part of the hydrologic cycle.
Calcium carbonate dissolving in soil water and ground water.
How does urbanization affect runoff and infiltration in a small, previously forested, drainage basin.
Infiltration decreases; runoff increases
_____ describes the total sediment load transported by a stream.
Sea level falls; land rises
_____ is an abandoned, cutoff, meander loop.
An oxbow
What is the release of water vapor to the atmosphere by plants?
Evapotranspiration
Which component of the hydrologic cycle describes the recharge of water to the soil and groundwater systems?
Infiltration
Stream discharge is defined as the quantity of water flowing past a specific channel location per unit time.
True
For the same discharge, gradient, and channel cross-section, a stream with a boulder bed would be more turbulent than one with a sandy bed.
True
Alluvium refers to stream deposits, mainly sand and gravel.
True
The lowest base level for most streams is lake level.
False
A stream flowing out from a lake cannot down it below the water surface elevation of the lake.
False
Forest beds are part of a deltaic, depositional sequence.
True
What stream characteristic is measured by the size of the largest particle that a stream can move?
Competence
What term does refer to sediments deposited from streams?
Alluvial
