Final answer:
Rain forests, oceans, and deserts clean the Earth's atmosphere.
Step-by-step explanation:
The correct answer is OA. Rain forests, OC. Oceans, and OD. Deserts clean the Earth's atmosphere.
Rain forests are known as the 'lungs of the Earth' because they produce oxygen through photosynthesis and absorb carbon dioxide, a greenhouse gas responsible for climate change.
Oceans play a crucial role in reducing atmospheric carbon dioxide levels. They absorb and store large amounts of carbon dioxide, helping to regulate global climate.
Deserts have a unique wind pattern that carries dust particles into the atmosphere. These dust particles act as nuclei for cloud formation and precipitation, contributing to the natural cleansing of the atmosphere.
