Question

Name the natural sources of emissions occurring in nature.

Hint:

Tip: Volcanoes, fires, dust storms = nature’s own emission sources!

Answer 1

Emissions can come from both human activities and natural sources.
Natural sources of emissions include various processes that release gases and particles into the atmosphere without human action.
Examples of natural sources are:
1. Volcanoes: Emit gases like sulfur dioxide (SO₂) and ash during eruptions.
2. Forest Fires: Release carbon dioxide (CO₂), carbon monoxide (CO), and smoke particles.
3. Dust Storms: Carry dust and fine particles over long distances.
4. Oceans: Emit salt particles and gases like dimethyl sulfide.
5. Plants and Trees: Release volatile organic compounds (VOCs) such as isoprene.
6. Animal Respiration and Decay: Produce carbon dioxide and methane (CH₄).
These natural emissions play a role in the Earth’s atmospheric balance and cycles.
