In which atmospheric layer is

• Troposphere

• Thermosphere

• Stratosphere

• Mesosphere

Layers of the atmosphere are classified according to changes

in temperature. Is the statement correct?

• No, because it depends on the events that is

  happening on that layer.

• Yes, because there is a significant change in temperature in each layers of the

  atmosphere.

• No, because layers of the atmosphere were classified based on their altitude alone.

• Yes, because from troposphere to exosphere the

  temperature is gradually increasing.

Which of the following are the vital roles of Earth’s atmosphere?

II. Provides the oxygen that we breathe

III. Protects us from harmful UV radiation

IV. Helps regulate the temperature on Earth

• II and III only

• III and IV only

• I, II and III only

• II, III and IV only

Rovic, a pilot of a large jet chose to fly in the stratosphere to avoid the weather systems. Is his decision correct?

• Yes, because weather phenomenon exists

  only in the troposphere.

• Yes, because the temperature in the

  stratosphere is increasing.

• No, because weather system occurs in all

  layers of the atmosphere.

• No, because most of the weather

  phenomenon occurs at the stratosphere.
