| what is equivilant to 1 Gt? |
|
Definition
| 1 Pg (petagram)=1 million metric tons= 1.12 regular tons |
|
|
Term
| Name the Anthropogenic carbon sources |
|
Definition
Fossil Fuel consumption 7.4 Gt
Land use change Emmissions 1.0 Gt
Cement making .5 Gt |
|
|
Term
| What are Anthropogenic carbon sinks? |
|
Definition
| Reservoirs where anthropogenic carbon sources accumulate |
|
|
Term
| Where are the carbon Sinks? |
|
Definition
Atmosphere 4.1 Gt
Ocean 2.3 Gt
Land Vegetation 1.4 Gt
Inferred Soil and Sediment 1.1 Gt |
|
|
Term
| How do we infer Soil and sediment Carbon Deposits? |
|
Definition
Emissions = accumulation
the difference is inferred to be in soil and sediments |
|
|
Term
| Describe Sedimentary Rocks and its relationship to carbon |
|
Definition
| largest carbon reservoir Limestone contains the most carbon due to crystaline structure shale is the most common and can have carbon from fossils it often does not so contains little amounts of carbon |
|
|
Term
| Describe fossil fuels in the Long term carbon cycle |
|
Definition
3rd largest reservoir
Coal is formed from compaction of carbon matter in terrestrial or marine lands
oil is formed when enough pressure heats it
natural gas is formed from further heating
when they rise up through impermeable layers they from oil fields |
|
|
Term
| Economic facts about coal oil and natural gas |
|
Definition
enough gas to last 40 years, low quality refined will last 100 years
enough NG to las 100 years
coal for 200 years |
|
|
Term
|
Definition
| limited supplies of oil can be extracted at costs that is less than the consumer can be charged for it it is expected anytime from 2020 to 2060 |
|
|
Term
| Describe the Inorganic movemement of carbon |
|
Definition
high latittudes are carbon sinks and low latitudes are carbon source
this is because of upwelling low latitueds brings carbon to the surface from collected sinking organics
temp and dissolution: colder temperatur makes it easier for C02 to be deposited in surface water. why beer has more fizz cold |
|
|
Term
| Carbonate rocks int he Inorganic Movement of carbon |
|
Definition
Calcium carbonate and carbonic acid occurs in the ocean normally but also when plankton form their shells this acts as a carbonate pump and adds carbon to the marine sediments.
allows more c02 to be depostited in surface waters and causes climate to cool |
|
|
Term
| Chemical weathering of calcium carbonate |
|
Definition
when limestone dissolves it realeases carbon adding to the ocean-atmosphere system where it will become c02
this creates acid rain |
|
|
Term
| Silicate Rocks and the Inorganic carbon cycle |
|
Definition
Silicone and oxygene
formation: igneous rocks metamorphism of carbonates and silicates
formation causes warmin by realeasing C02 the weathering will cause cooling by removing c02 from the atmosphere |
|
|
Term
| Feedback Between climate and the silicate weathering |
|
Definition
| GHE increases cause temp and rainfall to increase, increasing rate of silicate weathering removing C02 from the atmosphere, reduces temp and rain faill and decreases silicate weathering increasing C02 in the atmosphere, negative loop helps keep stability |
