Greenhouse gases (AQA GCSE Chemistry Combined Science): Flashcards

Gases that trap heat & maintain Earth's temperature

Carbon dioxide ($CO_2$), methane ($CH_4$), water vapour

Carbon dioxide ($CO_2$)

Methane ($CH_4$)

-18°C without, +15°C with

Natural process where greenhouse gases trap heat in atmosphere

Short-wavelength radiation

Long-wavelength radiation

Absorb it and trap it

Burning coal, oil and gas for energy

Less trees to absorb $CO_2$ from atmosphere

Animals release $CH_4$ when digesting grass

Bacteria decompose food waste & release $CH_4$
