Answers
1
Which zone receives the most direct sunlight?
the tropics
south polar zone
north temperate zone
south temperate zone
2
In general, cool air can carry ________ moisture, while warm air can carry ________ moisture.
less, more
less, less
more, more
more, less
3
Briefly describe the pattern called
thermohaline circulation
.
cooler, saltier water at the poles sinks
cooler, saltier water at the equator sinks
warmer, less salty water from the equator moves toward poles
warmer, less salty water from poles moves toward the equator
4
Which of the following is
NOT
a
proxy indicator
used to determine past climate?
weather reports
sediments
tree rings
ice cores
5
What information can be gained from studying sediments?
climate that produced the plants and pollen trapped
frequency of droughts and forest fires
composition of ancient atmosphere in bubbles
warm, wet years versus colder or drier years
6
Which zone receives more energy from the Sun? Which receive less energy?
The southern hemisphere receives more energy.
The northern hemisphere receives more energy.
The poles receive more energy.
The tropics receive less energy.
7
Where do global wind patterns come from?
the Sun interacting with Earth's magnetosphere
the hydrologic cycle
convection currents caused by uneven heating
rotation of Earth
8
How do scientists determine CURRENT climate conditions?
direct measurements
indirect measurements
proxy indicators
weather reports
9
What is the
greenhouse effect
?
increase in Earth's average surface temperature
pattern of cooler water sinking and warmer water rising
greenhouse gases prevent radiation, keeping heat near Earth
absorption and scattering of ultraviolet radiation by ozone
10
What information can be gained from studying tree rings?
warm, wet years versus colder or drier years
climate that produced the plants and pollen trapped
frequency of droughts and forest fires
composition of ancient atmosphere in bubbles
11
Sunlight that reaches Earth might be...
electrified
absorbed
transmitted
reflected
12
Which zone receives less direct sunlight?
south temperate zone
the tropics
north temperate zone
south polar zone
13
What information can be gained from studying ice cores?
composition of ancient atmosphere in bubbles
climate that produced the plants and pollen trapped
frequency of droughts and forest fires
warm, wet years versus colder or drier years
14
What is the definition of global warming?
rising sea levels as a result of thermal expansion
fracturing and melting of polar ice sheets and glaciers
increase in Earth's average surface temperature
changes in temperature, rainfall, wind patterns, and storms
15
How would climate zones be affected if Earth's axis were not tilted at all?
Climate zones would be reversed.
Climate zones would still be laid out as at present.
There would be no climate zones.
There would be no seasons (perpetual spring).
16
How would this diagram look different in the month of the July?
Northern Hemisphere would be tilted toward the Sun.
The Sun would hit the equator head on.
Southern Hemisphere would be tilted away from the Sun.
The Sun would be placed to the right
17
What are
proxy indicators
?
types of indirect evidence serving as substitutes for direct
amount of carbon dioxide emissions from a person or group
direct evidence of climate change
programs that simulate or imitate climate processes
18
What would happen to most of the sunlight that reaches Earth, if Earth had no atmosphere?
It would reflect out into space.
It would be conducted away.
It would be absorbed.
It would miss the Earth.
19
How do scientists determine PAST climate conditions?
proxy indicators
weather reports
direct measurements
indirect measurements
20
How does altitude affect an area's climate?
Precipitation falls on the windward side of mountain ranges.
DIfferent kinds of plants grow at different elevations.
Air pressure decreases with altitude, even at/near equator.
Air temperature decreases with altitude, even at equator.
21
How do the oceans affect Earth's climate?
absorb carbon dioxide for a cooling effect
redistribute heat through thermohaline circulation
absorb the Sun's radiation to retain heat
release carbon dioxide for a warming effect
22
Is the greenhouse effect a good thing, a bad thing, or a little of both?
Bad, increased greenhouse gases result in global warming.
Both, it is necessary to life, but increasing temperatures.
Good, this natural process makes life possible on Earth.
23
Why does the tilt of Eath's axis result in seasons?
The Sun heats different parts of the Earth unevenly.
The Moon causes cyclical high and low tides.
Earth is farther from the sun at some times than others.
Intensity of sunlight varies with the sunspot cycle.
