Carbon Cycle Processes

What is the definition of precipitation?

moisture (rain, hail. snow) falling from clouds to the ground.

What is the chemical equation for precipitation?

Water + Carbon Dioxide ——> Carbonic Acid

What are the impact of rising concentration of Carbon Dioxide in atmosphere on ocean surface waters?

Carbon Dioxide will react with ocean surface water and become acidic and warmer

What are the spheres involved in the Carbon transfer of precipitation?

Atmosphere (carbon dioxide) -> ocean (carbonic acid)

What is the chemical equation for Photosynthesis?

Carbon Dioxide + Water ——> Glucose + Oxygen 

What is the energy conversion for photosynthesis?

Light energy —-> chemical energy

What is the average flux from atmosphere to land plants & phytoplankton?

120 GT / year from atmosphere to land plants & phytoplankton

What are the spheres involved in the carbon transfer of Photosynthesis?

Atmosphere (carbon dioxide) -> biosphere (glucose for respiration – maintaining growth, reproduction, life processes)

What is the type of weathering?

In situ breakdown of rocks at or near the Earth’s surface by chemical, physical, biological processes

What are the different types of weathering?

Most involves acidic rainwater (CO₂ from either atmosphere or from respiring organisms in the soil) as a chemical agent

How does physical weathering indirectly accelerate carbonation?
