a)
increase by 0.8
b)
increase by 1.0
c)
increase by 0.6
d)
increase by 0.4
4.
Why are winter ice layers darker than the summer layers in the ice core?
a)
the force
b)
illusion
c)
salting
d)
compaction
5.
Why are these error bars smaller near the year 2000 than in the 1890s?
a)
better graphing technique
b)
better technology
c)
Ms. Batko made a mistake
d)
worse methods of collecting data
6.
The graph shows that the temperature for the past 10,000 years, compared with the previous 400,000 years, has been:
a)
getting warmer
b)
staying stable
c)
getting cooler
7.
What two things can happen when energy from the Sun interacts with the ground?
a)
absorbed & reflected
b)
absorbed & refracted
c)
absorbed & transmitted
d)
reflected & refracted
8.
Carbon dioxide keeps infrared radiation:
a)
on the ground
b)
in the air
9.
Carbon dioxide can absorb both infrared and solar radiation.
a)
True
b)
False
10.
How does atmospheric carbon dioxide affect global temperature?
a)
more CO2, lower temperature
b)
less CO2, lower temperature
c)
less CO2, higher temperature
d)
more CO2, higher temperature
11.
What happens if you remove all of the carbon dioxide from the atmosphere? The temperature:
a)
decreases
b)
increases
c)
stays the same
12.
Carbon dioxide traps heat, causing the temperature to increase. If there is no carbon dioxide, the heat can “escape” Earth’s atmosphere (instead of getting trapped) and the temperature will not rise.
a)
True
b)
False
13.
What happens when sunlight hits greenhouse gas molecules?
a)
quickly cools them, decreasing temperature
b)
slowly cools them, decreasing tempature
c)
quickly heats them, increasing temprature
d)
slowly heats them, increasing temperature
14.
When particles come in contact with each other, they pass heat to each other.
a)
True
b)
False
15.
How do carbon dioxide (CO2) and other greenhouse gases cause Earth's atmosphere to warm?
a)
absorb incoming solar radiation
b)
reflect incoming solar radiation
c)
absorb outgoing infrared radiation
d)
emit outgoing infrared radiation.
16.
Which factor was represented by the purple arrows in the Earth system model (Module 2)?
a)
solar radiation
b)
infrared radiation
c)
greenhouse gases
17.
What is one cause of the carbon dioxide increase over the past 50 years?
a)
tree farms
b)
fossil fuel use
c)
medicine
d)
technology
18.
During the winter, carbon dioxide increases (as opposed to the summer) because people use LESS fossil fuels in the winter to heat buildings.
a)
True
b)
False
19.
How many years of data are available from the Vostok ice core?
a)
50
b)
50,000
c)
420,000
d)
4,000,000
20.
What happens when energy from the Sun encounters a white surface (ice or snow)? The energy is:
a)
reflected off the surface and leaves the atmosphere
b)
reflected off the surface and trapped in the atmosphere
c)
absorbed by the surface and stored in the land and ocean
d)
absorbed by the surface, radiating heat into the atmosphere
21.
Describe how changes in the amount of ice covering Earth's surface can affect Earth's temperature.
a)
more ice, more reflection, cooler temperature
b)
more ice, less reflection, cooler temperature
c)
more ice, more absorption, cooler temperature
d)
more ice, less absorption, warmer temperature
22.
Currently, about 10% of Earth is covered with ice year-round. If this ice melts, what could happen to Earth's temperature?
a)
decrease in temperature
b)
increase in temperature
c)
rise in sea level
d)
rise of zombie polar bears
23.
How do the changes in cloud cover affect Earth's temperature?
a)
more clouds, higher temperature
b)
more clouds, lower temperature
c)
less clouds, lower temperature

b)
bottom image (2005)
25.
