Crops reduce erosion, increasing the amount of soil entering the river
d)
Crops absorb pure water from soil, causing the remaining water to contain more salt.

A student drew the model to represent a part of a watershed and some human activities that affect the watershed. How do the industrial, agricultural, and residential activities of humans most likely affect the groundwater in the area?
a)
The activities prevent most of the water from evaporating into the atmosphere
b)
Pollutants from the activities percolate through the soil and enter the water table
c)
The activities replace the groundwater used.
d)
All of the above
145.
A student sets up the investigation show below. The movement of colored water through the gravel best models-
a)
condensation of water vapor
b)
surface runoff of precipitation
c)
conservation of water
d)
pollution of groundwater
146.
Some areas of an ocean are known as dead zones. These zones form when excess organic material decomposes. This increased decomposition uses up the oxygen from the water. Which human activity is most affected by the increasing number of dead zones in the ocean?
a)
Offshore oil drilling, because water in dead zones is toxic
b)
Commercial fishing, because fish cannot survive without oxygen
c)
Commercial shipping, because dead zones change the course of ocean currents
d)
Sand mining, because oxygen is not available to form the sands of ocean beaches
147.
A coastal area that once supported a thriving fishing industry is overfished. The number of species found living in the marine ecosystem decreases. Which of these activities is most likely to increase the natural biodiversity in the area?
a)
Building artificial reefs and limiting fishing activity
b)
Introduction non-native species to fill unoccupied habitats and banning fishing
c)
Building artificial reefs and increasing fishing activity
d)
Eliminating non-native species and encouraging fishing for large predatory fish
148.
Which of these human activities is most likely to cause the excessive growth of phytoplankton in the world's oceans?
a)
The use of chemical fertilzers that are carried by runoff into rivers
b)
The logging of old-growth forests, which results in erosion
c)
The spraying of chemical herbicides that reduce carbon dioxide in the air
d)
The mining of fossil fuels, which requires digging underground tunnels
149.
A company known as Arten Industries is wanting to build a factory in the watershed that is pictured. The company wants to limit the ecological impact it has on surrounding areas. Where should the company build its factory?
a)
top of the river so the rain can dilute the pollution
b)
away from the river so the pollution can not reach the river
c)
the middle of the river so the pollution can have time to settle.
d)
the bottom of the river so it effects a smaller amount of land
150.
As the map shows, there are multiple drainage basins in Texas. Ft. Worth and Dallas are in the same drainage basin. What is the most likely reason that the water in the Trinity River is dirtier in Houston than it is in Dallas?
a)
Ocean pollutants are entering the river.
b)
Pollutants are entering from other drainage basins.
c)
The river basin picks up more human pollutants.
d)
The water goes through a salt dome and get more polluted.
151.
The following computer model was created to illustrate how a watershed can be affected by human activities. What is the most likely reason for placing the farm land upstream from the factories?
a)
The water at the highest point of the river will have been impacted the least by human activities, so it should be the cleanest.
b)
Farms do not have a negative impact on watersheds, so they should be placed upstream.
c)
The factory puts pollution into the air, so it does not matter where the farm is located.
d)
The farm should be placed upstream because pesticides from the farm will end up in the river, which is beneficial for the factories downstream.
152.
What is a watershed?
a)
An area or ridge of land that separates waters flowing to different rivers, basins, or seas.
b)
Land consisting of marshes or swamps; saturated land.
c)
Water that collects on the surface of the ground.
d)
Water held underground in the soil or in pores and crevices in rock.
153.
What is an aquifer?
a)
A body of permeable rock which can contain or transmit groundwater.
b)
The upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water.
c)
Area that contains both air and water
d)
Land consisting of marshes or swamps
154.
What is permeable mean?
a)
Filter gradually through a porous surface or substance.
b)
Rain, snow, sleet, or hail that falls to the ground.
c)
The state or quality of a material or membrane that causes it to allow liquids or gases to pass through it.
d)
Having small spaces or holes through which liquid or air may pass.
155.

Farmers can best reduce negative effects on the water quality of nearby streams and lakes by planting crops that

a)

produce less oxygen

b)

produce less carbon dioxide

c)

need less fertilizer

d)

need less solar energy

156.

a)

Human visitors to coral reef systems break corals growing on rocks

b)

Humans catch marine fish at a faster rate than the fish are able to reproduce

c)

Humans raise fish in a hatchery for commercial sale

d)

Humans construct artificial reefs to attract tourists
