The geological process that returns carbon dioxide to the atmosphere would be volcanic activities.

Geological processes and carbon dioxide

Geological processes are natural processes associated with the physical composition of the earth.

Respiration and decomposition both return carbon dioxide to the atmosphere but are more of biological processes rather than geological ones.

Transpiration has nothing to do with carbon dioxide but water molecules.

Volcanic eruption involves the release of molten lava and gas associated with volcanoes. The gas is a mixture of carbon dioxide, oxides of sulfur, etc.
