The mixing of cold Arctic Ocean water with warm surface Atlantic currents off the northwestern coast of Europe causes which effect?
sinking of water as it circulates southwest
reversal of current direction back toward the European coast
rise in water salinity and upwelling of affected currents
rapid evaporation and acceleration of currents toward the pole
Because water is able to exist in the liquid phase on Earth, water helps to moderate temperatures across the entire planet. Which statement BEST illustrates this link between water in the liquid phase and moderation of temperatures?
The movement of water creates heat.
Ocean currents circulate heat away from the equator.
Earth’s internal heat is pushed outward through volcanic activity.
Land warms as ocean water makes direct contact with land.
What will most likely happen if a warm ocean current travels north or south from the equator?
The current will become warmer, causing it to become more dense and rise.
The current will become cooler, causing it to become less dense and rise.
The current will become cooler, causing it to become more dense and sink.
The current will become warmer, causing it to become less dense and sink.
A scientist wants to track contaminant movement in the Gulf Stream. The Gulf Stream is a warm water current in the North Atlantic Ocean and is part of the North Atlantic gyre. The gyre is influenced by the Coriolis effect. To follow the contaminant after it exits the Gulf Stream, the scientist needs to know characteristics of the North Atlantic gyre. Which of these BEST describes a movement of the North Atlantic gyre the scientist needs to know?
linear movement due west
linear movement due south
clockwise movement
counterclockwise movement
If a northern coastline such as the Norway coast is located near a warm ocean current
the climate will be colder than normal for that latitude.
the climate will be warmer than normal for that latitude.
spring is longer than normal for that latitude.
spring is shorter than normal for that latitude.
In the hydrologic cycle, which process contributes to a decrease in groundwater levels?
infiltration
evaporation
precipitation
condensation
A rural, forested area receives a lot of rain in a short amount of time. What would most likely cause potential flooding in the area?
if the area has a large uncharged aquifer beneath it
if the water level in the area is below the zone of saturation
if the ground of the area is already saturated with water
if the ground of the area is mostly sandy soil
Look at the diagram of a stream with toxic chemicals flowing into it.This diagram models how toxic runoff can pollute a stream and also
produce acid rain.
cause soil erosion.
create algae blooms.
pollute groundwater.
During this event, which of these water cycle processes has MOST likely slowed down or stopped completely?
surface runoff
groundwater discharge
evaporation
infiltration
Which is the most common contamination source for freshwater resources?
runoff
digging wells
melting of glaciers
lightning
A regional water board is examining proposals to provide drinking water to a growing metropolitan area. Which of these proposals is MOST likely to deplete groundwater supplies?
installation of city-owned wells within each neighborhood
construction of a dam to create a large water reservoir
placement of stations along a river to capture and filter water
establishment of a water treatment plant next to a large lake
Which is the best way to conserve worldwide freshwater resources?
build more roads and highways for cars and trucks
increase the amount of land used to raise cattle
develop more modern coal-powered plants
use more efficient irrigation techniques
Over-using an aquifer can lead to subsidence. Which other hazard would MOST likely be exacerbated by this subsidence?
climate change
earthquake
drought
flooding
A student created a diagram of farmland with runoff from cornfields to a nearby pond. What was the student probably trying to model?
how acid rain kills pond plants
how pond water is use to irrigate crops
how fertilizers can get into ponds and cause algae blooms
how toxic chemicals from industrial wastes can poison pond water
The REUWS study examined residential water use in North America in 1999. This study measured gallons of water used per household per day (gphd) in twelve cities. Researchers repeated the study in certain cities in 2012. The graph compares the results of the first study to results from households in Tacoma, Washington, more than a decade later.Assume that behaviors surrounding water use have not changed significantly since the last study. Under this assumption, which of the following manufacturers could claim to have achieved the greatest success in the development and marketing of water conservation technology?
toilet manufacturers
clothes washer manufacturers
shower head manufacturers
dishwasher manufacturers
Which human activity directly affects the quality of freshwater resources?
depleting the ozone layer
burning gasoline in car engines
throwing trash out of car windows
allowing runoff from agricultural fields
How will the presence of power plants burning fossil fuels MOST likely affect the water cycle?
Sulfur and nitrogen emissions will dissolve in rainwater to form acid rain.
Runoff containing emissions will cause very large algal blooms in ponds.
Emissions will cause the pH of surface waters to increase.
Emissions will decrease the amount of precipitation.
The greenhouse effect is a process by which atmospheric gases, including help warm the atmosphere and surface of Earth. Most scientists think the greenhouse effect is increasing due to human activities. Which of these human activities has caused the greatest increase in concentrations of atmospheric
planting trees
recycling aluminum
burning fossil fuels
using nuclear power
Nuclear power and drilling for oil can both negatively affect ecosystems. Which negative impact can only be caused by nuclear power?
air pollution
water contamination
exposure to uranium
spread of invasive vegetation
How are surface mining and peat harvesting similar in the way they affect an ecosystem?
Both increase air pollution, causing acid rain.
Both flood the area with water, decreasing soil erosion.
Both release carbon dioxide, decreasing global temperatures.
Both remove vegetation in the area, destroying habitats.
Which could increase the amount of greenhouse gases in the atmosphere?
planting trees in areas that have been deforested
reducing the use of gasoline-powered vehicles
burning coal to produce electricity
creating wind farms in desert areas
Raising livestock, such as sheep and cattle, results in the production of large amounts of methane gas (CH4). Methane has a similar effect in the atmosphere as carbon dioxide (CO2). As more livestock are raised to provide food for humans, what is the MOST likely effect of the increase in methane?
acid rain
ozone thinning
water pollution
global warming
