Unit 6 Test Revi

Why do planes fly in the stratosphere, the second-lowest layer of the atmosphere?

• to avoid storms and other weather events that occur in the troposphere
• to receive better radio communication which is aided by higher ozone levels in the stratosphere
• to fly at supersonic speeds without air resistance
• to avoid changes in air pressure

Which of the following correctly lists the layers from Earth moving upward in the correct sequence?

• troposphere, stratosphere, mesosphere, thermosphere
• thermosphere, mesosphere, stratosphere, troposphere
• troposphere, mesosphere, thermosphere, stratosphere
• mesosphere, troposphere, thermosphere, stratosphere

Which two layers of the atmosphere experience temperature INCREASE with altitude?

• Troposphere &thermosphere
• Troposphere &mesosphere
• stratosphere & mesosphere
• stratosphere & thermosphere

What is in the stratosphere that absorbs sun rays and causes an overall increase in temperature as altitude increases?

• Radiation
• Mesopause
• Ozone
• Tropopause

If Jasmine is standing on top of Mt. Everest and Joseph is standing on Earth’s surface, which of the following would be the MOST true?

• Joseph would face colder temperatures because he is at a lower altitude.
• Jasmine will face colder temperatures because she is at a higher altitude.
• Jasmine will face warmer temperatures because she is at a higher altitude.
• Jasmine and Joseph will experience the same temperatures.

What is the major difference between weather and climate?

• air temperature
• air pressure
• humidity
• length of time over which the two are measured

Which of the following is an example of climate?

• the current temperature in Pinehurst, NC
• the relative humidity in Raleigh, NC
• the average current temperature in a region
• the average atmospheric conditions in Raleigh, NC over the past 30 years

Which of the following describes a group of short-term atmospheric conditions in the atmosphere over a certain area?

• climate
• weather
• barometric pressure
• humidity

What is a front?

• Radiation heating the ground
• A warm air mass.
• A large body of air.
• The border where air masses meet.

What is the main factor that leads to the formation of a hurricane?

• Convection occurring more quickly as warm air rises and colder air sinks
• Dry, hot winds meeting moist air over a cold ocean
• The rapid cooling of a cyclonic wind system
• Wind speeds slowing down and causing an increase of winds behind it
