Natural sources of CO2:
* Volcanic eruptions: Volcanoes release CO2 into the atmosphere.
* Respiration: All living things, including humans and animals, breathe out CO2 as a byproduct of respiration.
* Decomposition: When organic matter, like dead plants and animals, breaks down, it releases CO2.
* Ocean: The ocean absorbs and releases CO2.
Human-made sources of CO2:
* Burning fossil fuels: This is the largest source of human-made CO2. Fossil fuels, like coal, oil, and natural gas, are burned to generate electricity and power vehicles.
* Deforestation: When forests are cut down or burned, the stored carbon is released into the atmosphere as CO2.
* Industrial processes: Many industries, like cement production and manufacturing, release CO2.
Examples of CO2 in everyday life:
* Carbonated drinks: CO2 is dissolved in water to create the fizz in carbonated drinks like soda.
* Fire extinguishers: Some fire extinguishers use CO2 to extinguish flames by displacing oxygen.
* Dry ice: Solid CO2 is called dry ice. It is used for special effects like fog and for keeping things cold.
Impact of CO2 on the environment:
CO2 is a greenhouse gas. It traps heat in the atmosphere, contributing to global warming and climate change.
