Questions
Hydrosphere - Correct Answer ✅ - ocean absorbs heat
- warmer ocean causes more intense storms,
absorbs most of the heat
- increased storm frequency + intensity
- sea level rise (ex: high tide flooding)
- ocean absorbs CO2 (increased acidity)
- organisms require carbonate ions for skeleton
- more CO2 leads to less carbonate and more H+,
so corrosive to shells + skeletons
- CO2 + H2O <---> H2CO3 <---> H+ +HCO3- <--->
2H+ + CO3-2
What impact does acidification (reduced pH) have on marine
life? - Correct Answer ✅ - corrosion of skeletons
- cannot adapt to change in pH that quickly
