ATMOS Exam #1 UPDATED ACTUAL
Exam Questions and CORRECT Answers
At night, as the air temperature falls, what typically happens to the relative humidity? -
CORRECT ANSWER - It will increase
Which of the following is not considered to be a basic property of the atmosphere? - CORRECT
ANSWER - wind chill
The tropopause can be thought of as a "lid" on Earth's weather. - CORRECT ANSWER -
true
What is the average value of sea level pressure? - CORRECT ANSWER - 1013.25 mb
When dew forms on Earth's surface, it results in __________ of the air temperature. -
CORRECT ANSWER - an increase
Layers of the atmosphere from lowest to highest altitude - CORRECT ANSWER -
troposphere, stratosphere, mesosphere, thermosphere
What term describes the amount of water vapor in the atmosphere compared to the atmosphere's
capacity for moisture at a given temperature? - CORRECT ANSWER - relative humidity
Most of the mass of Earth's atmosphere is located between the surface and approximately 12 km
(7.5 miles). - CORRECT ANSWER - true
In general, where in the troposphere is temperature the coldest? - CORRECT ANSWER -
at the tropopause
, A north wind means that the wind is blowing from - CORRECT ANSWER - the north to
the south
Which of the following atmospheric gases is the most plentiful in the atmosphere, by percent by
volume? - CORRECT ANSWER -
Pressure is a measure of the weight of air above a unit area. - CORRECT ANSWER -
Which atmospheric variable can exist naturally in all three phases in Earth's atmosphere? -
CORRECT ANSWER - water
Deep storms can occur in the tropics where the tropopause is at a high altitude. Storms in the
polar regions are more shallow because the tropopause is not as high over the poles. -
CORRECT ANSWER -
As temperature decreases overnight, the relative humidity typically increases. - CORRECT
ANSWER - true
What term describes the pressure at which the air contains the maximum amount of water vapor
possible for the observed temperature and pressure? - CORRECT ANSWER -
The altitude of the tropopause varies with latitude. Where is the tropopause the highest? -
CORRECT ANSWER -
Closely spaced isobars on a weather map are indicative of a strong pressure gradient force and
fast winds. - CORRECT ANSWER -
If an air column is cooled through radiational cooling, what will happen to the surface pressure?
- CORRECT ANSWER -
