Lesson Worksheet: The Ozone Layer Science

In this worksheet, we will practice explaining the importance of the ozone layer and the ways in which it can be damaged.

Q1:

Which of the following is a balanced reaction equation for the formation of ozone?

  • AOO23
  • BOO+O32
  • CO+OO23
  • D2O3O33
  • EO2O+O23

Q2:

In high concentrations, the color of ozone can be observed. What color is ozone gas?

  • APale blue
  • BWhite
  • CDark blue
  • DPale yellow
  • EGreen

Q3:

Which of the following is not an action we can take to protect the ozone layer?

  • AAvoiding using products that contain CFCs
  • BBuying local goods to reduce transportation
  • CEnsuring air conditioners do not leak
  • DUsing more insecticides on crops
  • EWalking and cycling to minimize car use

Q4:

Why is the ozone layer essential to surface-dwelling life on Earth?

  • AThe ozone layer filters out harmful UV rays from the Sun.
  • BThe ozone layer provides a weather-free zone for aircraft to fly through.
  • CThe ozone later acts as a shield preventing meteors from hitting the surface of Earth.
  • DThe ozone layer helps birds navigate during their yearly migrations.
  • EThe ozone layer allows clouds to form as part of the water cycle.

Q5:

What unit is used to measure the amount of atmospheric ozone?

  • ADobson
  • BJoule
  • CGram
  • DCelsius
  • ERichter

Q6:

Consider the following equation: O2O2 What is responsible for causing the oxygen molecule to split into two free oxygen atoms?

  • ACarbon dioxide
  • BHeat from the Sun
  • CGreenhouse gases
  • DAcid rain
  • EUltraviolet radiation

Q7:

Why is it that ultrasonic aircraft can negatively impact the ozone layer?

  • AThe aircraft create powerful sound waves.
  • BThe aircraft exhaust contains nitrogen oxides.
  • CThe aircraft heat up the ozone.
  • DThe aircraft exhaust contains carbon dioxide.
  • EThe aircraft disturb the clouds of ozone.

Q8:

In which layer of the atmosphere would you find the ozone layer?

  • ATroposphere
  • BStratosphere
  • CThermosphere
  • DMesopause
  • EExosphere

Q9:

In September of each year in the Antarctic, the rate of ozone destruction increases. Why does the formation of these Antarctic ozone holes occur during September?

  • ASeptember is springtime in the Antarctic and a lot of methane gas is created by animals coming out of hibernation.
  • BSeptember is summertime in the Antarctic and the region receives more sunlight.
  • CSeptember is fall in the Antarctic and the fishing season brings many boats that pollute the ice.
  • DSeptember is springtime in the Antarctic and sunlight reaches the region.
  • ESeptember is a busy industrial period for Argentina, Australia, and South Africa and levels of air pollution increase.

Q10:

What is the chemical formula of a molecule of ozone?

  • ACO
  • BO
  • CCO2
  • DO2
  • EO3
