Process And Movement Of Carbon

Question 1

8 processes that move carbon

Answer 1

Photosynthesis
Respiration
Decomposition
Combustion
Combustion 
Sequestration
Ocean uptake and loss
Oceanic carbon pumps
Volcanic activity

Question 2

Photosynthesis info

Answer 2

Carbon from atmosphere to biomass
Plants and phytoplankton use light energy to change CO2 and H20 info glucose and oxygen
Carbon passed on in food chain and released my respiration and decomposition

Question 3

Respiration info

Answer 3

Carbon from living organisms (biosphere) to atmosphere

Pants and animals break down glucose for energy - real ease CO2 and CH4

Over geologic time more O in and more CO2 removed as some organic matter stored in sedimentary rocks

Question 4

Decomposition info

Answer 4

Dead biomass to atmosphere and soil

Bacteria and fungi break down organisms releasedkng CO2 and CH4

Carbon transferred to soil as humus - litter of decomposition

Question 5

Combustion info

Answer 5

Carbon from living, dead and decomposed biomass to atmosphere via Burling

Wildfires can naturally cause carbon flow

Question 6

Sequestration info

Answer 6

Carbon from atmosphere to rocks and fossil fuels

Question 7

Ocean uptake and loss

Answer 7

CO2 dissolves from atmosphere to ocean
Forms carbon acid. CO2+H2O + H2CO3
Which can form calcium carbonate bicarbonate

Can transfer from ocean to atmosphere when carbon rich water rises to surface

Carbonic acid - water slightly acidic - weathers rock and earths surface adding calcium carbonate ions fo water

Question 8

Oceanic carbon pumps

2 types

Answer 8

Negative correlation between temp of water and amount of CO2 that can be dissolved
Leads to vertical deep mixing

Warm water in oceanic surface currents carried from warm tropics to cold polar regions - water is cooled - becomes dense - sinks below surface layer - this is the CARBON PUMP, ensures constant exchange between air and sea

Living things in ocean move carbon from atmosphere - surface later with photosynthesis to deal ocean and rocks in shells and decomposition - this is the BIOLOGICAL PUMP

Question 9

Volcanic activity info

Answer 9

Never chases detetectablr global warming

Also releases sulphur dioxide which can covert to sulphuric acid - forms fine droplets - increase reflection of radiation to space - cooling earths atmosphere
