There are many different watersheds in the United States. The boundaries of a watershed are determined by
number of people in the region
the number of rivers
height of the land
type of weathering
A __________ is where sediments often build up at the mouth of a river, where it enters a larger body of water.
delta
alluvial fan
deposition
topography
T/F - Planting trees or grass can reduce the amount of erosion in a watershed.
True
False
Able to allow water to pass through
Impermeable
Runoff
Ground water
Permeable
Surface runoff in a watershed that empties into the Mississippi river watershed has become polluted by sewage and fertilizers.
Which of the following environments might become polluted as a result?
I. surface water in the watershed
II. the groundwater in the watershed
Ill. the ocean that the Mississippi river flows into
I only
ll only
I and ll
l, ll, and lll
The name of the line that is the upper level of the zone of saturation:
Zone of Saturation
Zone of Aeration
Water Table
Watersheds contain both groundwater and surface water. Gravity causes water to seep into the ground or flow downhill to the lowest point. How can groundwater become surface water?
Groundwater cannot flow up against the force of gravity, so ground water cannot become surface water
The surface of the land is below the level of the water table and a stream or lake will form
The rocks become less permeable
That's just crazy talk. Groundwater stays in the ground forever.
Laura was creating a Venn diagram to compare an alluvial fan and a delta. Which statement would she place in the center?
Sediments are deposited by water when it slows down
Formed at the base of mountains (dry land)
Formed at the base of rivers when they reach bays, oceans or large lakes
Alluvial fans and deltas have nothing in common.
When is the test?

Wind and rain are major causes of erosion. Which area of Texas would most likely be affected by wind and rains from hurricanes?
Edward's plateau
Gulf coast prairie
Piney Woods of East Texas
Cross timbers
What form of chemical weathering might will cause a rock to turn red?
Oxidation forms rust
Acid rain is dissolving the rock
Abrasion
Hydrolysis
Deltas and alluvial fans are both formed by the deposition of rivers when the water slows down and the sediments fall out of the the water. How is a delta different from an alluvial fan.
A delta is at the base of a mountain and an alluvial fan is at the top of the mountain
An alluvial fan is at the base of a mountain and a delta is where the river empties into a lake, bay or ocean
Deltas and alluvial fans are the same thing
Deltas get larger and turn into alluvial fans.
