Geology Lesson 12
Gravel
Which of the following is most porous?
False
Geysers are hot springs formed where the temperature of the water is above boiling point.
Wave
A delta that has islands reworked by waves on the seaward side, such as the Nile delta, is typically formed as in a(n) ____-dominated delta.
Stream
A delta with long fingerlike sand bodies, each deposited in a distributary channel that progrades far seaward, such as the Mississippi River, is typically formed as in a(n) ____-dominated delta.
True
A dry surface has a higher infiltration capacity than a moist surface.
False
A trellis drainage is a tree branchlike pattern of streams.
False
A v-shaped cross section and an irregular profile characterize a well-developed or "old" valley.
True
Agriculture is the primary user of groundwater in the United States.
False
Alluvial fans are formed where running water flows into another body of water.
False
Along a graded stream, no sediment is eroded, transported, or deposited.
Quartz sandstone
An example of a rock type which could be a good aquifer is
Shale
An example of a rock/sediment type which could be an effective aquiclude is
False
As long as limestone is present near the surface, karst topography will form in any climate.
True
Braided streams have an intricate network of dividing and rejoining channels.
False
Caves do not form in marble because it is a dense and hard rock.
Humid climate and carbonate bedrock at a shallow depth
Conditions needed for the development of karst topography include
Recharge is less than discharge
Current production of groundwater from the High Plains Aquifer cannot be sustained because
Incised meanders
Deep, meandering canyons cut into bedrock are called:
Dendritic
Identify the type of drainage system illustrated here:
Derranged
Identify the type of drainage system illustrated here:
Radial
Identify the type of drainage system illustrated here:
Rectangular
Identify the type of drainage system illustrated here:
Trellis
Identify the type of drainage system illustrated here:
False
If rocks are porous rocks, then they are permeable also.
False
In hilly country the groundwater table's highest elevation occurs in stream valleys and around lakes.

Match the features of a stream labeled in the image:
4. emerging springs 2. aquitard 5. zone of aeration 3. perched aquifer 1. water table 6. zone of saturation
Match the features of ground water to the labeled numbers in the figure: emerging springs aquitard zone of aeration perched aquifer water table zone of saturation
False
Most detrital rocks are neither porous nor permeable.
False
Once an aquifer has been contaminated it "cleanses itself" rather rapidly because the contaminants adhere to rock/sediment particles.
It is not inexhaustible
One of the reasons that geothermal energy is not as widely used as it could be because
1. Deeply entrenched permanent stream 2. Solution Valley 3. Emerging Springs 4. Sinkholes 5. Disappearing Streams 6. Caves

True
Porosity of igneous rocks is generally less than that of sedimentary rocks.
streams have cut valleys below the regional water table AND where an impermeable layer intersects the surface AND where a perched water table intersects the surface
Springs occur where
Florida, Kentucky, Tennessee, Indiana, Missouri
States in which extensive karst topography exists include
Position
Streams of rivers possess two kinds of energy. Potential energy is the energy of:
True
Subsidence can occur as the result of extraction of oil.
False
The gradient of a stream does not change over the length of the stream.
Precipitation that infiltrates the ground
The major source of groundwater is
70%
The percentage of the Earth's surface that is covered by water is about:
0.65%
The percentage of the Earth's water that is fresh water that is not frozen is:
Bed load and suspended load
The solid particles of a stream include:
False
The total load of a sediment a stream can carry consists of suspended load and bed load.
Sea level
The ultimate base level for a stream is:
False
The water table is flat, featureless surface between the zones of aeration and saturation.
discharge is more than recharge
The water table is lowered when
Early Stage/Young Stream

Late Stage / Old Age Stream
What type of stream or stage is in the image:
Middle Stage / Mature Stream
What type of stream or stage is in the image:
Rejuvinated Stream
What type of stream or stage is in the image:
water infiltrating from precipitation AND water infiltrating from septic systems AND water infiltrating from the base of glaciers
Which of the following would be considered groundwater?
From areas of high pressure to areas of low pressure
Within the zone of saturation, water always moves
