Carbon Dioxide (CO2)
Definition
Carbon dioxide is a colorless gas naturally present in Earth's atmosphere. It is released through natural processes like respiration and volcanic eruptions but also through human activities such as burning fossil fuels. CO2 is a major greenhouse gas contributing to global warming.
Analogy
Imagine carbon dioxide as a cozy blanket wrapped around our planet. Just like how a blanket traps heat close to your body, CO2 traps heat close to Earth's surface causing it to warm up.
