Question

this diagram shows a model of the carbon cycle. which numbered point in the diagram represents the exchange of carbon through a geological process? a. 1 b. 2 c. 3 d. 4

Explanation:

Step1: Identify geological process

Geological processes involve long - term changes in Earth's crust.

Step2: Analyze each option

1 is photosynthesis (biological), 2 is respiration (biological), 3 is fossil fuel combustion (geological as it involves fossilized carbon), 4 is volcanic activity (geological but less directly related to carbon exchange in the way fossil fuel use is in this context). So the carbon exchange through a geological process is represented by 3.

Answer:

C. 3
