5 years
How long does it take for carbon in the land biosphere to turn over?
20 years
How long does it take for carbon in the ocean mixed layer to turn over?
6 years
How long does it take for carbon in the deep ocean to turn over?
hundreds of years
What is the arrow from atmosphere going to land biosphere?
photosynthesis
What is the arrow from land biosphere going to atmosphere?
decay and decomposition
cellular respiration
What is the arrow from the atmosphere going to the ocean mixed layer?
CO2 dissolving
precipitation
What is the arrow from ocean mixed layer going to the atmosphere?
evaporation
What is the arrow going from the ocean mixed layer to the deep ocean?
currents
What is the arrow going from the deep ocean to the ocean mixed layer?
currents
Why aren’t there any arrows going to or from permafrost?
carbon does not move in permafrost
What do the arrows represent?
carbon moving from one place to another
What do the numbers next to the arrows represent?
how many gigatons of carbon per year are transferred from one place to another
What do the numbers in the boxes represent?
amount of carbon stored in those areas
What is the arrow going from rocks to carbon cycle?
volcanoes
What is the arrow going from carbon cycle to rocks?
chemical weathering
pressure decay
What is pressure decay?
rapid burying of dead plants/animals before they decay and release CO2
how fossil fuels are formed
What does a higher amount of CO2 in the atmosphere do to the temperature?
increases it
How many years does it take for carbon in rocks to turn over?
millions and millions of years
