25
The temperature variations in the four layers of the atmosphere are due to the way _____ energy is absorbed as it moves (which way - upward or downward) through the atmosphere.
solar | downward
26
What is the primary absorber of solar energy?
The Earth's Surface
27
Some of the solar energy absorbed by the earth's surface is reradiated by the Earth as ________ which warms the overlying ______.
heat | troposphere
28
What is the boundary called between the troposhpere and the stratosphere?
The Tropopause
29
The global average temperature in the troposphere rapidly ________ with altitude until the tropopause.
decreases
30
The temperature begins to ________ with altitude in the stratosphere.
increase
31
The warming in the stratosphere is caused by a form of oxygen called ___________ with the symbol ____.
ozone | O3
32
The ozone (03) absorbs ultraviolet _________ from the ______.
radiation | sun
33
What protects us from most of the sun's ultraviolet radiation?
Ozone
34
Ultraviolet radiation from the sun can cause: a. acne b. cancer c. genetic mutations d. cavities in your teeth e. sunburn f. b, c, and e
f. b, c, and e
35
Scientists are concerned that human activity is contributing to a (decrease or increase) in stratospheric ozone.
decrease
36
Nitric Oxide is caused from exhaust of ____ _______ _____ and chlorofluorocarbons (CPCs), which are used as __________, may contribute to _______ depletion
high flying jets refrigerants ozone
37
The layer of Earth where weather occurs
Troposphere
38
At the stratopause, the temperature stops ______ with altitude.
increasing
39
Why does the overlying mesosphere have a decreasing temperature with altitude?
Because the mesosphere does not absorb solar radiation
40
At the mesopause, the temperature begins to _____ with altitude and continues in the _________.
increase | thermosphere
41
At the mesopause, ________ ________ hits the Earth's atmosphere and _____ it.
solar radiation | heats
42
Because the atmosphere is so _____, a thermometer cannot measure the temperature accurately and special instruments are needed.
thin
43
What is the basis for dividing the atmosphere into four layers?
Height and Temperature
44
``` Does the temperature increase or decrease with altitude in the: troposphere?______ mesosphere?______ stratosphere?______ thermosphere?_____ ```
troposphere?Decrease mesosphere? Decrease stratosphere? Increase thermosphere? Increase
45
What is the approximate height and temperature of the tropopause?
12-20 km; -56 degrees C
46
What is the approximate height and temperature of the stratopause?
48-52 km; -2 degrees C
47
What is the approximate height and temperature of the mesopause?
84-92 km; -86 degrees C
48
The lower stratosphere is cold at about _____ degrees Celsius.
-60
49
Why is the upper stratosphere warmer than the lower stratosphere? And, what causes that?
The upper stratosphere contains a layer of ozone. | The ozone in the stratosphere absorbs energy from the sun which is converted into heat and warms the air.
