WC16 - Carbon Transfers
Respiration
- process living organisms production of energy
- Plants & animals break down glucose for energy, releasing carbon dioxide and methane (a gas containing carbon) into the atmosphere.
-
decomposition
- in the state of rotting or breaking down
- Decomposition tranfers carbon from dead biosphere and the soil. After death, bacteria and fungi break organisms down, CO2 and methane are released. Some Carbon is transferred into the soil.
-
photosynthesis
- the process of plants turning carbon into organic material
- plants use energy from the sun to change CO2 and water into glucose & oxygen, this enables plants to grow. carbon is then passed through the food chain & released through respiration and decomposition
- From biosphere to atmosphere
Combustion
- Process of buring something
- wildfires and smouldering of peat contribute to more rapid release. combustion transfers carbon stored in living, dead or decomposed biomass to the atmosphere by buring
-
Burial & compaction
- burying something closely packed together
- Decomposed plants and animals, lived millions of years ago, been buried. Overtime, ayers of organic matter, greatly compressed to form today's carbon rich oil.
-
Sequestration
- CO2 is removed from the atmosphere and held in solid or liquid form
- Atmosphere to hydrosphere
- Carbon from the atmosphere can be sequestered (captured & held) in sedimentary rocks or as fossil fuels. Rocks and fossil fuels form over millions of years when dead animal and plant material in the ocean falls to the floor and is compacted.
Weathering
- Process of being worn by long exposure to the atmosphere
- Atmospheric Carbon reacts with water vapour making acid rain --> chemical reaction occurs when rain falls to rock, dissolving the rock. Molecules caused by the reaction may be washed into the sea, reacting with CO2 dissolved in water, forming Calcium carbonate, which is used by sea creatures.
- Atmosphere to the Biosphere and Hydrosphere
