Question

explain how the rate at which fossil fuels are transferred into the atmosphere, as shown in the diagram, has altered the carbon cycle during the past 250 years.

Explanation:

Fossil fuel burning releases large - amounts of carbon dioxide into the atmosphere. In the past 250 years, this has increased the atmospheric carbon pool. It disrupts the natural balance of the carbon cycle as the rate of carbon release is much faster than natural sequestration processes like photosynthesis and carbon burial. This leads to higher atmospheric CO₂ levels, contributing to global warming and climate change.

Answer:

The rapid transfer of carbon from fossil fuels to the atmosphere over the past 250 years has increased atmospheric carbon dioxide levels, disrupting the natural balance of the carbon cycle and contributing to climate - related changes.
