Explanation

The Montreal Protocol on Substances that Deplete the Ozone Layer was enacted to phase out the production and consumption of ozone-depleting substances, protect the ozone layer, and prevent skin cancer.

Multiple choice

What is the layer of the atmosphere closest to the Earth's surface called?

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface to an altitude of about 10 kilometers.

Multiple choice

What is the primary mechanism that drives the global circulation of the atmosphere?

  1. Coriolis Effect

  2. Jet Stream

  3. Pressure Gradient

  4. Solar Radiation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The pressure gradient between areas of high and low pressure drives the movement of air, resulting in wind and weather patterns.

Multiple choice

  1. Photolysis

  2. Radiolysis

  3. Hydrolysis

  4. Polymerization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Polymerization is the process by which smaller molecules combine to form larger, more complex molecules, and it is believed to be responsible for the formation of complex organic molecules in planetary atmospheres.

Multiple choice

Which air pollutant is primarily responsible for the depletion of the ozone layer?

  1. Chlorofluorocarbons (CFCs)

  2. Hydrochlorofluorocarbons (HCFCs)

  3. Halons

  4. Methyl bromide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chlorofluorocarbons (CFCs), once widely used in refrigeration, aerosols, and foam blowing agents, are potent ozone-depleting substances that contribute to the destruction of the stratospheric ozone layer.
