A benchmark is
a permanent marker on the ground that indicates locations ans elevation
The principle of inclusion states that
a sedimentary rock must be younger than the clasts that it contains
Groundwater is unique among all the erosional agents because it
carves landscapes from below the surface
The water table is lowered
during periods of drought
The principle of superposition can be used to determine the relative ages of all of these except
folded sedimentary rocks
Sinkholes typically have steep-walled sides because
gravity causes the roof of an area hollowed by solution to collapse
Contour lines on a map connect points
of equal elevation
The zero contour line is also known as
sea level
What most likely will happen if the water table is at the surface of the ground
Small depression fill with water, basement will flood, water from heavy rain will not sink
Spits and barrier islands are
deposited by longshore drift.
If a sequence of sedimentary rocks has been folded and is now vertical
graded bedding can determine if beds are older or younger than neighbors
The_______of a stream are where it begins, and its________is/-where if flows into another body of water
headwaters; mouth
By what feature(s) might submergent shorelines be characterized typically
highly irregular coastlines, numerous bays and headlands, sand and lagoons, ALL OF THE ABOVE
The sinuosity of a stream is measure of
how much it meanders
During longshore drift, sand grains move
in a zigzag pattern
Groundwater is the part of the hydrosphere in which water does which of the following
seeps into sediment pores, flows through bedrock fractures, leak into the ground, ALL OF THE ABOVE
The severity of the impact of coastal hurricanes on the shoreline depends on which of the following
the path of the eye of the hurricane, whether the storm comes onshore at high tide or low tide, wind velocity, all of the above
The dominant cause of erosion along lake and ocean shorelines is
waves
By what motion(s) do sediment particles move in a stream?
sliding, rolling, bouncing, ALL OF THE ABOVE
An angular unconformity is evidence that
there is an incomplete geologic record preserved in an area.
Which of the following could be the base level of stream
all of the above
Contour lines on a topographic map
are spaced at equal distances from one another horizontally
Small tick marks (hachures) on contour lines indicate
depressions
The gradient of a stream describes
the steepness of its path through the landscape.
The term relative age refers to
whether a feature is older or younger than another
