1.11. Carbon Stores (major)

Question 1

Marine sediment and sedimentary rock %

Answer 1

69%

Question 2

Ocean %

Answer 2

26%

Question 3

Fossil fuel deposits %

Answer 3

2.7%

Question 4

Soil organic matter %

Answer 4

1%

Question 5

Atmosphere %

Answer 5

0.005%

Question 6

Soil organic matter

Answer 6

• soil contains rotten organic matter
• important carbon stores
• carbon can remain in soil for 100s of years
• deforestation, land use, and soil erosion can release stored carbon rapidly

Question 7

Atmosphere

Answer 7

• carbon held in form of co2
• amount increased due to power stations, vehicles and deforestation -> enhanced greenhouse effect

Question 8

Terrestrial plants

Answer 8

• vital for life
• convert sun’s energy to carbohydrates
• store carbon for years and transfer to soil
• deforestation- carbon released back into atmosphere

Question 9

Marine sediments and sedimentary rocks

Answer 9

• largest store of carbon
• a long term store with rocks taking millions of years to form

Question 10

Ocean

Answer 10

• very important carbon store
• co2 absorbed directly from air and river water discharges carbon carried in solution
• since Industrial Revolution, oceans have absorbed more co2 from air from increased co2 emissions

Question 11

Fossil fuel deposits

Answer 11

• hydrocarbons= important long term store of carbon
• since Industrial Revolution, oceans absorbed more co2 from increased co2 emissions
