• A. It absorbs longer wavelengths of the electromagnetic spectrum while transmitting shorter wavelengths.
• B. It absorbs shorter wavelengths of the electromagnetic spectrum while transmitting longer wavelengths.
• C. It absorbs all wavelengths of the electromagnetic spectrum.
• D. It transmits all wavelengths of the electromagnetic spectrum.

Answer 1

The correct option is A

It absorbs longer wavelengths of the electromagnetic spectrum while transmitting shorter wavelengths.

Gases that trap heat in the atmosphere are called greenhouse gases. Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.
