oceanic pumps

combustion

respiration

photosynthesis

burial and compaction

weathering

carbon sequestration

2 oceanic pumps and what they do

vertical deep mixing

• water cools and sinks at high latitudes and returns to be warmed and rises at lower latitudes- upwelling

biological pump

• c exists with marine life, released when die and some dinks to bottom creating sedimentary rocks

what happens during combustion

turns into energy can be vegetation or fossil fuels

released into atmosphere

what happens during respiration

plants store carbs as energy source

converted into energy from growth and repair etc

returned to atmosphere

what happens during photosynthesis

plants use light H20 and co2 to convert into glucose

used in respiration

converted into starch as storage

what happens during burial and compaction and example

organic matter sinks and forms layers on sea bed

sediment eventually forms hydrocarbons

shelled organisms contain CaCO3, dissolve or compacted into limestone when die

what happens in weathering

breakdown of rocks in original place

absorbed by rainwater and carbonic acid formed- transported through water cycle to oceans

2 examples of carbon sequestration

geological

terrestial

geological sequestration

co2 captured at source

injected as liquid underground

sinks to depths and in circulation for years

more capable than terrestial

terrestial sequestration

plants to capture co2

enriches plants but released when die
