2.
As you increase altitude within the troposphere, temperature
a)
increases, this is due to that the Earth radiates the heat back to space

stays the same
d)
does not change
3.
The stratosphere is important due to that
a)
it has an ozone layer, within which it protects life from infrared radiation which would otherwise cause us to burn.
b)
it has an ozone layer, within which it protects life from ultra-violet radiation which would otherwise cause us to burn.
c)
it burns up meteors.
d)
contains the aurora borealis.
4.
As the altitude increases in the stratosphere, temperature tends to
a)
decrease
b)
increase
c)
stay the same
d)
none of these
5.
The process of convection transfers heat energy _____.
a)
from cold areas to warm areas
b)
from warm areas to cold areas
c)
from high altitudes to low altitudes
d)
from humid areas to dry areas
6.
Winds transfer energy in the atmosphere by the process of _________.
a)
conduction
b)
convection
c)
radiation
d)
precipitation
7.
What is the relationship between altitude and air density within Earth's atmosphere?
a)
As altitude increases, air density decreases.
b)
As altitude increases, air density increases.
c)
As altitude increases, air density remains the same.
d)
There is no relationship between altitude and air density within Earth's atmosphere.
8.
Why does air density decrease with increasing altitude within Earth's atmosphere?
a)
Air density decreases with increasing altitude because more atoms escape into outer space.
b)
Air density decreases with increasing altitude because temperature decreases with increasing altitude.
c)
Air density decreases with increasing altitude because the gravitational pull exerted by the Earth decreases with increasing altitude.
d)
Air density decreases with increasing altitude because energy from the sun pushes the air particles closer to Earth.
9.
Within which atmospheric layer is the highest concentration of ozone found?
a)
troposphere
b)
stratosphere
c)
mesosphere
d)
thermosphere
10.
List the layers of Earth's atmosphere in order of increasing altitude.
a)
exosphere, thermosphere, mesosphere, stratosphere, troposphere
b)
troposphere, stratosphere, mesosphere, thermosphere, exosphere
c)
troposphere, stratosphere, ozone layer, mesosphere, thermosphere, exosphere
d)
stratosphere, mesosphere, thermosphere, exosphere, troposphere
11.
which is not an example of convection?
a)

a)
ionosphere
b)
o-zone layer
c)
troposphere
d)

16.
Energy from the Sun travels to Earth as ______.
a)
conduction
b)
convection
c)
insulation
d)
radiation
17.
1. This picture shows warm air rising and cool air falling in a cycle. This is an example of which process?
a)
Conduction
b)
Convection
c)
Radiation
18.
3. The Sun’s rays take about 8 minutes to reach Earth’s atmosphere. Which process describes the thermal energy transfer between the Sun and the Earth?
a)
Conduction
b)
Convection
c)
Radiation
19.
9. In the water cycle, sunlight causes water to evaporate, rise to form clouds, fall as precipitation, flow into a body of water, and begin the cycle again. What type of energy transfer is occurring as the evaporated water rises?
a)
Conduction
b)
Convection
c)
Radiation
20.
What happens to the air pressure (density) of air as you increase in altitude?
a)
density increases, this is due to the surface area of the atmosphere increasing as you increase altitude which allows for gas molecules to expand.
b)
density decreases, this is due to the surface area of the atmosphere increasing as you increase altitude which allows for gas molecules to expand.
c)
density stays the same
d)
density disappears
21.
Which of the following is one of the reasons why air density & air pressure decrease with increasing altitude?
a)
Air density & Air pressure decrease with increasing altitude due to that gravity forces the gases of the troposphere towards the center of the Earth. Thus, gas molecules will be greatest at seal level.
b)
Air density & Air pressure decrease with increasing altitude due to that the surface area of the Earth's atmosphere decreases with increasing altitude, thus gas molecules can spread out.
c)
Air density & Air pressure increase with increasing altitude. So the following question is worded wrong.
d)
none of the answers are correct
22.
The mesosphere is an important layer within the atmosphere due to that
a)
this is the layer where weather occurs.
b)
this is the layer where the ozone layer is located, within which it absorbs UV radiation.
c)
this layer burns up the meteors and comets that enter the Earth's mesosphere. This is due to the particles heating the objects as they enter the atmosphere.
d)
this is the layer where the space shuttle is located.
23.
Temperatures in the thermosphere tend to
a)
increase, this is due to the UV radiation being able to penetrate the through this part of Earth's Atmosphere.
b)
decrease, this is due to that it is very cold in space.
c)
remain the same
d)
does not change
24.
What form of energy causes water to change from a liquid to a gas?
a)
heat
b)
sound
c)
waves
d)
light
