Which of the following activities are the largest contributors of greenhouse gases?

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.

Which of the following is the most basic definition of a greenhouse gas?

Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.

Which two of the following are strong greenhouse gases?

Main Greenhouse Gases

Greenhouse gas Major sources
Carbon Dioxide Fossil fuel combustion; Deforestation; Cement production
Methane Fossil fuel production; Agriculture; Landfills
Nitrous Oxide Fertilizer application; Fossil fuel and biomass combustion; Industrial processes
Chlorofluorocarbon-12 (CFC-12) Refrigerants

Which correctly lists three greenhouse gases?

Answer: carbon dioxide, nitrous oxide, methane. Explanation: because other gases that accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature.

Which of the following best describes the greenhouse gas effect?

Which of the following best describes how the greenhouse effect works? A planet’s surface absorbs visible sunlight and returns this absorbed energy to space as infrared light. Greenhouse gases slow the escape of this infrared radiation, which thereby heats the lower atmosphere.

Which definition describes global warming?

Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.

How does the greenhouse effect work quizlet?

How does the greenhouse effect work? Visible light is emitted through the sun and passes through the infrared-blocking greenhouse gases. The light then warms the surface of the earth and turns into infrared heat, which is then trapped in the atmosphere and reflected by greenhouse gases.

Which of the following is a greenhouse gas that comes only from human sources?

Greenhouse Gases : Example Question #3 Which of the following greenhouse gasses is produced only by anthropogenic means? Explanation: The only gas in these selections that is made only by man is , which is a CFC or Chlorofluorocarbon. , methane, can be produced by many other organisms; a key example of this are cows.

What is the strongest greenhouse gas?

Water vapor

Is aerosol a greenhouse gas?

Aerosols are defined as microscopic liquid or solid particles that enter the atmosphere through natural and man-made processes. Aerosols are more complicated than the typical greenhouse gas. There are some aerosols that cause cooling while others cause warming.
