Final answer:
Volcanic activity is the natural force responsible for releasing carbon dioxide and other atmospheric gases from deep within the Earth. Volcanic eruptions have historically contributed to the formation of Earth's atmosphere, although the burning of fossil fuels is currently the primary source of CO₂ emissions.
Step-by-step explanation:
The natural force responsible for the release of carbon dioxide and other atmospheric gases is volcanic activity. When a volcano erupts, it emits a variety of gases, including carbon dioxide (CO₂), water vapor (H₂O), and sulfur dioxide (SO₂), among others. The gases released by volcanoes are sourced from deep within the Earth and can also include recycled materials that have been subsumed by plate tectonics. In the past, such volcanic emissions are believed to have contributed to the formation of Earth's early atmosphere.
While volcanic activity is a natural source of atmospheric gases, it is worth noting that today, the burning of fossil fuels constitutes the primary source of CO₂ emissions. This anthropogenic activity releases far more CO₂ than volcanic eruptions and is a significant contributor to global warming.
