BIOLOGY - Environment - Carbon Cycle part 2

The video explains the formation of fossil fuels from ancient organic matter and their extraction through fracking. It discusses the natural carbon cycle, highlighting how carbon dioxide is recycled in nature. The impact of burning fossil fuels, which adds new carbon dioxide to the atmosphere, is contrasted with the natural cycle. The video also covers the usage of fossil fuels, emphasizing that most are burned for energy, while a small portion is used for manufacturing. Recycling is presented as a sustainable practice that can help manage carbon emissions and support the natural cycle, including oceanic processes.

What process is used to extract natural gas from shale?

• Pumping

• Drilling

• Fracking

• Mining

How does the natural carbon cycle differ from the burning of fossil fuels?

• It only occurs in oceans

• It recycles recently captured carbon

• It adds new carbon dioxide to the atmosphere

• It does not release carbon dioxide

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

• 10%

• 20%

• 50%

• 90%

What is a better alternative to burning plastics?

• Using them as fuel immediately

• Throwing them in the ocean

• Recycling them

• Burying them

What is the role of the carbon cycle in the oceans?

• It only affects land

• It stops recycling

• It dissolves carbon dioxide and oxygen

• It creates new matter
