Understanding the Carbon Cycle and Climate Change

The video explains the natural carbon cycle, detailing how carbon is stored in living things, soil, oceans, atmosphere, and rocks. It describes how carbon is released through natural events and human activities, particularly the burning of fossil fuels, which significantly increases carbon emissions. The video emphasizes the need to reduce carbon emissions to combat global warming, highlighting that planting trees alone is insufficient and urging a halt to excess carbon release.

What happens to the carbon stored in plants and animals when they die?

• It remains in the soil permanently.

• It is released back into the atmosphere.

• It turns into fossil fuels immediately.

• It disappears completely.

Over millions of years, what can some of the carbon stored in ancient trees and sea life become?

• Atmospheric gases

• New plant life

• Water vapor

• Fossil fuels and rocks

Which natural event can release carbon trapped in rocks?

• Earthquakes

• Volcanic eruptions

• Hurricanes

• Tsunamis

How much more carbon do humans release compared to all the volcanoes on Earth each year?

• 100 times more

• 60 times more

• 10 times more

• 20 times more

Why is planting more trees not enough to achieve net zero carbon emissions?

• Trees cannot absorb all the excess carbon.

• Trees are not effective in urban areas.

• Trees take too long to grow.

• Trees release carbon at night.

What is the only sure way to stop global warming according to the video?

• Stop releasing excess carbon into the air

• Use more fossil fuels

• Plant more trees

• Increase volcanic activity
