Answer:

Effective lowering of base level

Question 2: Which of the following has the highest permeability?

Answer:

Gravel

Question 3: What is the energy source that drives the entire hydrologic cycle?

Answer:

The Sun Question 4: What type of acid in solution (water) is present to dissolve limestone to form caves and sinkholes?

Answer:

Carbonic

Question 5: Streams transport 3 forms of what sediment loads?

Answer:

dissolved load, suspended load, bed load

Question 6: Suspended loads are?

Answer:

carried in the water column

Question 7: What permits ground water to flow in the subsurface?

Answer:

hydraulic gradient, gravity, aquifer properties - favorable porosity and permeability.

Question 8: What is a delta?

Answer:

a location where rivers enter a large body of water that form a triangular shape as the river deposits sediments and switches course.

Question 9: What is base level?

Answer:

The lowest elevation to which water can erode or flow.

Question 10: A high density of extraction wells and aggressive pumping can?

Answer:

cause cones of depression, and even intersecting cones of depression, lowering the local water table, cause some wells to go dry, and lower the regional water table.

Question 11: Define what is meant by a river's CAPACITY?

Answer:

Measure of the total amount of sediment a stream can carry

Question 12: How are coarse gravel or boulders transported by streams?

Answer:

Bed load

Question 13: Bed loads are?

Answer:

carried by the stream along its bottom Question 14: What type of drainage pattern would you expect to form on a stratovolcano?

Answer:

Radical

Question 15: Define competence

Answer:

Ability of a stream to transport a particular size of material

Question 16: Clay has a high porosity but poor permeability - why?

Answer:

The pore spaces are too small to allow water to travel through the rock.Question 17: How much ground subsidence has occurred in San Joaquin Valley in California due to excessive groundwater removal?

Answer:

• meters

Question 18: Where the stream velocity increases along a cut bank, what also increases?

Answer:

Erosion

Question 19: The boundary between the two zones is the?

Answer:

Water table

Question 20: What percentage of Earth's surface water is fresh surface water?

Answer:

About 1.2%

Question 21: Ground water flows parallel to groundwater contours (lines of equal subsurface groundwater elevation)?

Answer:

False

Question 22: What determines a river's capacity?

Answer:

Discharge and flow velocity of the stream Question 23: Entrenched meanders on streams like the Colorado or San Juan flowing on the Colorado Plateau in Utah are a result of?

Answer:

Tectonic elevation of the Colorado Plateau

Question 24: What is a drainage basin?

Answer:

An area that collects and drains precipitation

Question 25: How does an oxbow lake form?

Answer:

when a meander is cut off and abandoned

Question 26: What determines a river's competence?

Answer:

Flow velocity

Question 27: Where would braided streams most likely occur?

Answer:

Streams with a high sediment load and steeper slopes

Question 28: What causes braided stream channels to form?

Answer:

nearby sources of coarse sediment
