carbon cycle Flashcards
what are the 6 major global carbon stores
marine sediments and sedimentary rocks
oceans
fossil fuel deposit
soil organic matter
atmosphere
terrestrial plants
what are the 4 FAST transfers in the carbon cycle
photosynthesis
respiration
decomposition
combustion
what are the 4 SLOW carbon transfers in the carbon cycle
Burial and compaction
weathering
volcanic activity
carbon sequestration
what is the largest store of carbon
sedimentary rock
how is carbon stored in the ocean
absorbed from the air / river
what is fossil fuel deposit
hydrocarbons
long term carbon storage
however the industrial revolution has exploited them
how long is carbon stored in soil organic matter
carbon remains in soils for 100s of years
how is carbon released from organic matter
deforestation, land use change and soil erosion is releases the carbon
what is carbon held in the atmosphere as
carbon dioxide
where do terrestrial plants transfer carbon to
soil
how does photosynthesis transfer carbon
definition of photosynthesis
process where plants use lights as energy from the sun to produce carbohydrates
what is respiration
chemical process that happens in plants and animals. co2 returned to atmosphere by exhale
what is decomposition
organisms die and are consumed by decomposers such as bacteria , fungi , earthworms
carbon from bodies is returned to the atmosphere
what is decomposition
organic materials contain carbon
when its burned co2 releases into the atmosphere
whAT IS BURIAL and compaction
where organic matter is buried by sediments and become compacted
what is weathering
breakdown or decay of rocks
what is volcanic activity
volcanic activity returns to the atmosphere
today volcanos emit between 130 million - 380 million tonnes of co2 per year
what is carbon sequestration
transfer of carbon from the atmosphere to plants , soils. rock formations and oceans
natural and human process
what is the relationship between carbon and tempature
as temperature increases more carbon dioxide is released
colder it is the less carbon dioxide is released
how does colder tempturtures impact carbon stores and transfers
how does warmer tempturtures impact carbon stores and transfers
3 natural variations which impact the carbon cycle
volcanic activity
sunspot activity
orbital changes
why have forest fires started in Indonesia
started deliberately and illegally to clear forests for paper and palm oil production
