3.Why should a model of the carbon cycle include the burning of fossil fuels?(1 point)

Burning fossil fuels moves carbon from the atmosphere to the hydrosphere.
Burning fossil fuels moves carbon from the atmosphere to the geosphere.
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Burning fossil fuels moves carbon from the hydrosphere to the atmosphere
Burning fossil fuels moves carbon from the hydrosphere to the atmosphere.

Burning fossil fuels moves carbon from the geosphere to the atmosphere.

Explanation:

A carbon cycle is a model that indicates how carbon is cycled across the spheres of the earth. Burning of fossil fuels  is part of this cycle indicating movement of carbon from the geosphere – since fossil fuels are derived from the geosphere (the rocks of the crust) - to the atmosphere as carbon dioxide. Again this carbon will cross over to the biosphere when taken up by plants from the atmosphere during photosynthesis
