Deck 7: Ecosystems and Habitat

Question 1

Scientists in the IPCC conduct original research and report their findings in periodic assessment reports.

Answer 1

False

Question 2

The average global temperature is warmer than it has ever been in Earth's history.

Answer 2

False

Question 3

Eruption of volcanoes can cause global cooling.

Answer 3

True

Question 4

Earth's atmosphere works exactly like a greenhouse.

Question 5

The thinning of the ozone layer will help reduce global warming.

Question 6

The melting of the Arctic ice cap will result in sea level rise.

Question 7

Melting mountain glaciers will result in a temporary increase in the amount of water available to people living downstream.

Question 8

Climate is changing more rapidly in the Arctic than in other regions of the globe.

Question 9

As the average global temperature warms, the thickness of ice on Antarctica may increase.

Question 10

The global conveyor belt refers to the thermohaline circulation.

Question 11

Water is a nonrenewable resource. Once we use it, it is gone.

Question 12

Most freshwater on the planet is frozen.

Question 13

An aquifer is a large deposit of groundwater.

Question 14

The "Tragedy of the Commons" was originally an article written by Garrett Hardin to describe aquifer depletion.

Question 15

Saltwater intrusion is a process which can contaminate water supplies.

Question 16

Impervious surfaces help to keep pollutants out of groundwater.

Question 17

Hydroelectric dams can result in the emission of methane, a greenhouse gas.

Question 18

Virtual water is the quantity of water embedded in the production of food or products.

Question 19

A vegetarian diet has a relatively high virtual water content.

Question 20

Deforestation of mountain slopes can provide a permanent increase in the amount of water available for irrigation as more snowmelt flows into reservoirs.

Question 21

The first step in a water conservation program is to begin replacing fixtures as quickly as possible.

Question 22

Automatic electronic flushing controls are a cost-effective strategy for water conservation.

Question 23

Desalination of seawater consumes more energy than pumping of groundwater.

Question 24

Copper roofs provide the best surface for rainwater harvesting.

Question 25

A rainwater cistern is always made of black polyethylene.

Question 26

Graywater is water from sinks, tubs, and toilets.

Question 27

Urban development results in increased stormwater runoff.

Question 28

Most stormwater features such as bioswales, rain gardens, or porous paving have two goals: cleansing and infiltration.

Question 29

Rain gardens are usually barrels placed under downspouts.

Question 30

A swale is a concrete drainage ditch.

Question 31

Most of the work of a porous paving system occurs in the aggregate-filled reservoir below the surface.

Question 32

Most of the Earth's total water is located

A) in lakes and rivers
B) in groundwater
C) in oceans
D) in glaciers

Question 33

Groundwater is

A) water that runs off the surface in a rainstorm
B) soil moisture
C) the zone of saturated soil or rock
D) water inaccessible to wells

Question 34

A water table is

A) flowing water in a streambed
B) the impervious rock layer that traps groundwater
C) an area of saturated soil
D) the top surface of groundwater

Question 35

The Ogallala is

A) a vast lake in Central Asia
B) a river in the Colorado drainage
C) the world's largest aquifer
D) a Himalyan glacier

Question 36

Potable water is water that

A) has been boiled
B) is suitable for drinking
C) cannot be used for drinking
D) has evaporated from a holding area

Question 37

The majority of the work of treating wastewater is accomplished by

A) chemicals
B) ultraviolet light
C) bacteria
D) plants

Question 38

Stormwater is

A) water that exceeds storm drain capacity
B) polluted runoff
C) water that falls as rain
D) water that reaches storm drains
