Document Summary

What would rising co2 do to ocean systems: carbonic acid is produced, breaks down to h+ and hco3 lowers ph and decreases the amount of carbonate, carbonate is important to react to calcium to make caco3, less carbonate = less precipitation, affects caco3 secreting organisms because they cannot produce skeletons and shells, reduced ph affects organisms with high metabolism because they are very ph dependent. What about the things we don"t see?

Turns into liquid and migrates out of source beds through permeable sediments until it gets trapped trapped areas hold oil and gas: best traps are buried rivers, beaches, deltas, reefs, or folded and faulted strata (cid:1) (cid:1) (cid:1)
