What Is The Carbon Cycle - Part 2

The video discusses the properties of Electra 4 and Group 7 elements, focusing on their reactivity. It then explores mankind's impact on the carbon cycle, highlighting the formation and use of fossil fuels, and the process of fracking. The natural cycling of carbon through respiration and waste is explained, contrasting it with the addition of carbon dioxide from burning fossil fuels. The importance of recycling and waste management is emphasized to mitigate carbon emissions. The video concludes with a reminder of the continuous recycling of matter in nature, both on land and in oceans.

What process is used to extract natural gas from shale?

• Drilling

• Pumping

• Fracking

• Mining

How is carbon dioxide naturally cycled in the environment?

• Through industrial processes

• Through photosynthesis only

• By burning fossil fuels

• Via respiration and decomposition

What is a key difference between burning wood and fossil fuels?

• Wood is a non-renewable resource

• Fossil fuels add new carbon to the atmosphere

• Wood releases more carbon dioxide

• Fossil fuels are captured from the atmosphere

What percentage of fossil fuels is typically used for making products like plastics?

• 50%

• 10%

• 25%

• 90%

Why is recycling plastics considered beneficial for the environment?

• It is more expensive than burning

• It increases carbon emissions

• It reduces the need for new fossil fuels

• It creates more waste
