METRO test question 2025 updated
questions n answers
Ocean weather in the higher latitudes is generally more severe in winter. Why do you think this
is? - correct answer ✔✔ All are correct
Standard unit of Atmospheric Pressure - correct answer ✔✔ millibar
Cyclone - correct answer ✔✔ A rotating area of low pressure
Anticyclone - correct answer ✔✔ A rotating area of high pressure
Barometer - correct answer ✔✔ Measures pressure in military or inches of mercury
Humidity - correct answer ✔✔ Water vapor in air
Thermometer - correct answer ✔✔ measures temperature
This is the most prevalent gas in the atmosphere. - correct answer ✔✔ Nitrogen
Most weather happens in this layer of the atmosphere: - correct answer ✔✔ Troposphere
The troposphere is, on average, 4 miles thick near the poles and 12 miles thick at the equator.
Why is this so? - correct answer ✔✔ Air in the tropics is warmer, and therefore less dense
,Heat travels through the mechanisms of conduction, radiation, and convection. Which of the
following would be an example of convection? - correct answer ✔✔ Warm air rising up a
chimney
Average atmospheric pressure at the surface is 1013 millibars. At an average height of 5640
meters (about 3.5 miles) it is only 500 millibars, or half of surface pressure. Why does pressure
drop so quickly when the atmosphere is over 100 miles thick? - correct answer ✔✔ Air is
compressed by gravity and most of its molecules are thus held close to the ground.
Which of the following is true about the troposphere? - correct answer ✔✔ All are correct
Greenhouse gasses trap heat by absorbing infrared radiation from the planetary surface. Which
of the following is NOT a greenhouse gas? - correct answer ✔✔ Argon
The troposphere cools with altitude. On average, the temperature drops at a rate of 6.5 celsius
per km. What is this quantity called? - correct answer ✔✔ The normal or standard lapse rate
Why are the tropics so much warmer than the poles? - correct answer ✔✔ All are correct
The sunlight that reaches earth is mostly in this band of the electromagnetic spectrum. - correct
answer ✔✔ Visible light
Earth warms its atmosphere from below by emitting long wave infrared radiation, aka "heat". -
correct answer ✔✔ True
Roughly what fraction of solar radiation actually reaches Earth's surface? - correct answer ✔✔
50%
, Which among these choices is the primary cause of seasonal temperature variations in each
hemisphere? (Why are summers warm and winters cold?) - correct answer ✔✔ Earth's
rotational axis maintains a 23.5 degree tilt as our planet orbits the sun.
Which day on the celestial calendar is connected to maximum daylight in a particular
hemisphere? - correct answer ✔✔ Summer solstice
Radiation of heat - correct answer ✔✔ Needs no medium
1 calorie - correct answer ✔✔ Raises 1 gram of water 1 degree celsius
Temperature - correct answer ✔✔ Measures the total thermal energy of a system, in units of
calories or joules
Heat - correct answer ✔✔ Measures the total thermal energy of a system, in units of calories or
joules
Incoming solar radiation - correct answer ✔✔ 1370 Watts per square meter
Albedo - correct answer ✔✔ Reflectivity of a surface
UV Radiation - correct answer ✔✔ Scattered by Ozone
Ozone - correct answer ✔✔ Triatomic oxygen, ( 03), found in the stratosphere
A weather report for your location tells you that the dew point is 68°F. Which of the following
best explains what this means? - correct answer ✔✔ All are correct
