ozone
The layer of Earth where weather occurs
Troposphere
At the stratopause, the temperature stops ______ with altitude.
increasing
Why does the overlying mesosphere have a decreasing temperature with altitude?
Because the mesosphere does not absorb solar radiation
At the mesopause, the temperature begins to _____ with altitude and continues in the _________.
increase
thermosphere
At the mesopause, ________ ________ hits the Earth’s atmosphere and _____ it.
solar radiation
heats
Because the atmosphere is so _____, a thermometer cannot measure the temperature accurately and special instruments are needed.
thin

troposphere?Decrease
mesosphere? Decrease
stratosphere? Increase
thermosphere? Increase
What is the approximate height and temperature of the tropopause?
12-20 km; -56 degrees C
What is the approximate height and temperature of the stratopause?
48-52 km; -2 degrees C
What is the approximate height and temperature of the mesopause?
84-92 km; -86 degrees C
The lower stratosphere is cold at about _____ degrees Celsius.
-60
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.
