Earth's Atmosphere and Ozone Layer Quiz

What are some natural causes of climate change?

• Volcanic eruptions, solar radiation variations, and natural greenhouse gas emissions.

• Human industrial activities and deforestation.

• Increased use of fossil fuels and urbanization.

• Changes in ocean currents and tides.

What is a 'hole' in the ozone layer?

• A region where the concentration of ozone is significantly lower than normal, often observed over Antarctica.

• A type of cloud formation that blocks sunlight.

• An area where ozone is produced in excess due to pollution.

• A phenomenon that occurs only in urban areas.

What are the effects of UV radiation on human health?

• Increased risk of skin cancer, cataracts, and weakened immune system.

• Improved vitamin D synthesis and stronger bones.

• Enhanced mood and mental health benefits.

• Reduced risk of eye diseases and better vision.

What is the ozone layer?

• A region of Earth's stratosphere that contains a high concentration of ozone (O3) and protects living organisms from harmful ultraviolet (UV) radiation.

• A layer of the atmosphere that is primarily composed of nitrogen and oxygen.

• A protective layer of carbon dioxide that traps heat in the atmosphere.

• A thin layer of water vapor that regulates Earth's temperature.

What is global climate change?

• A long-term change in the average weather patterns on Earth, often attributed to human activities such as burning fossil fuels.

• A temporary fluctuation in weather conditions due to seasonal changes.

• An increase in the Earth's temperature caused solely by natural phenomena.

• A decrease in biodiversity due to urbanization and deforestation.

What is the importance of monitoring the ozone layer?

• It helps to assess the effectiveness of policies aimed at protecting the ozone layer and understanding its recovery.

• It allows scientists to predict weather patterns more accurately.

• It is essential for measuring air pollution levels in urban areas.

• It provides data for the development of new energy sources.

How do chlorofluorocarbons (CFCs) affect the ozone layer?

• CFCs release nitrogen atoms in the stratosphere, which can destroy ozone molecules.

• CFCs release chlorine atoms in the stratosphere, which can destroy ozone molecules.

• CFCs have no effect on the ozone layer.

• CFCs absorb ultraviolet radiation, protecting the ozone layer.

What is the significance of the Montreal Protocol?

• An international treaty designed to phase out the production and consumption of ozone-depleting substances.

• A local agreement to promote recycling in urban areas.

• A global initiative to increase the use of fossil fuels.

• A treaty focused on reducing carbon emissions from vehicles.

What are greenhouse gases?

• Gases in Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

• Gases that are released during photosynthesis and are essential for plant growth.

• Gases that contribute to air pollution and are harmful to human health.

• Gases that are used in refrigeration and air conditioning systems.

What is the primary function of the ozone layer?

• To absorb the majority of the sun's harmful ultraviolet (UV) radiation, protecting living organisms on Earth.

• To provide oxygen for humans and animals.

• To regulate the Earth's temperature by trapping heat.

• To filter out all types of radiation from the sun.
