The vertical drop of a stream channel over a certain distance defines {gradient, alluvium, laminar flow, runoff, discharge}
gradient
The release of water vapor to the atmosphere by plants is called {degassing, infiltration, evaporation, transpiration, none}
transpiration
Which does not influence stream velocity? {channel roughness, discharge, gradient, laminar flow, channel size and shape}
laminar flow
A natural levee is {essentially parallel to its stream channel, a depositional feature essentially parallel to the stream channel, a depositional feature, an erosional feature, an erosional feature essentially parallel to the stream channel}
a depositional feature essentially parallel to the stream channel
The suspended load of a stream { usually consists of fine sand silt and claysized particles, is deposited before the bed load, consists primarily of highly soluble substances, moves along the bottom of the channel by rolling sliding and saltation, none}
usually consists of fine sand silt and claysized particles
As stream discharge increases {channel depth increases but width and stream velocity decrease| stream velocity channel width and channel depth all decrease | stream velocity channel width and depth all increase | stream velocity increases but channel width and depth decrease | none}
Stream velocity, channel width and depth all increase
The percentage of the total volume of rock or sediment that consists of pore spaces is called { head | permeability | hydraulic capacity | porosity | none}
Porosity
The boundary separating the zone of aeration and the zone of saturation is the {capillary fringe | aquitard | cone of depression | aquitop}
capillary fringe
At a bend in a rive, the main erosion is {on the outside of the bend | on the inside of the bend | both outside and inside | at the oxbow lake }
on the outside of the bend
The pattern that forms in areas underlain by alternating beds of resistant and less resistant rock in streams are nearly parallel to one another is a ________ pattern.
trellis
This drainage pattern occurs when streams diverge from a central high area like spokes from the hub of a wheel.
radial
The most common drainage pattern is ______.
Dendritic
When bedrock is criss-crossed by a series of joints and faults, a drainage pattern characterized by bends may develop. Such a drainage pattern is termed a ________ pattern.
rectangular
Where the underlying bedrock is relatively uniform, the pattern of streamflow is determined chiefly by the slope of the land. The drainage pattern that develops in such a situation is termed a _______ pattern.
dendritic
The continuous movement of water from the oceans to the atmosphere, from the atmosphere to the land, and from the land back to the sea is known as______.
The hydrologic cycle
