Exploring the Carbon Cycle

The video explains global warming and the greenhouse effect, highlighting how carbon dioxide and other gases trap heat in the atmosphere. It delves into the carbon cycle, showing how carbon moves between living and non-living things through processes like photosynthesis and respiration. The role of decomposers in breaking down dead matter and the formation of fossil fuels over millions of years are discussed. The video also covers the impact of burning fossil fuels on global warming and emphasizes the importance of controlling carbon dioxide levels in the atmosphere.

What is global warming?

• A type of weather phenomenon

• An increase in Earth's temperature

• A decrease in Earth's temperature

• A new type of greenhouse gas
