6 Questions

Which of the following best describes the greenhouse effect?

The trapping of heat close to Earth's surface by greenhouse gases

What is the function of the ozone layer?

To protect the planet from the sun's harmful ultraviolet (UV) radiation

What are CFCs?

Compounds containing chlorine, fluorine, and carbon used as agents that produce low temperatures

What are the main greenhouse gases responsible for trapping heat near Earth's surface?

The main greenhouse gases responsible for trapping heat near Earth's surface are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

What is the purpose of a catalytic converter in an exhaust system?

The purpose of a catalytic converter in an exhaust system is to convert toxic gases and pollutants in the exhaust gas from an internal combustion engine into less-toxic pollutants through a redox reaction.

How do fertilizers contribute to crop productivity?

Fertilizers contribute to crop productivity by providing essential nutrients, such as nitrogen, potassium, and phosphorus, that are required by plants. They also enhance the water retention capacity of the soil and increase its fertility.

Study Notes

The Greenhouse Effect

  • The greenhouse effect is a natural process that traps heat in the Earth's atmosphere, allowing the planet to maintain a habitable temperature.

The Ozone Layer

  • The ozone layer's primary function is to absorb UV radiation from the sun, protecting the Earth's surface and its inhabitants from harmful radiation.

Chlorofluorocarbons (CFCs)

  • CFCs are synthetic compounds used as refrigerants, propellants, and solvents, but they contribute to ozone depletion and are potent greenhouse gases.

Greenhouse Gases

  • The main greenhouse gases responsible for trapping heat near Earth's surface are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (such as CFCs).

Catalytic Converters

  • The purpose of a catalytic converter in an exhaust system is to reduce the emissions of harmful pollutants, such as carbon monoxide, nitrogen oxides, and volatile organic compounds, from internal combustion engines.

Fertilizers and Crop Productivity

  • Fertilizers contribute to crop productivity by providing essential nutrients, such as nitrogen, phosphorus, and potassium, which promote healthy plant growth and increase crop yields.

Test your knowledge on the greenhouse effect and ozone layer. Explore how these phenomena impact Earth's climate and the role of greenhouse gases in trapping heat.
