Above: The increase in concentration of carbon dioxide in the ocean with an increase in global temperatures. The increase in carbon dioxide and consequently acidity
Use the information on the website below to answer the following questions on ocean acidification
http://www.pmel.noaa.gov/co2/story/What+is+Ocean+Acidification%3F
Remember: Answer all questions in full sentences.
Q1) What are the building blocks for the skeletons and shells of many marine organisms?
Q2) What are the ions of calcium carbonate?
Q3) What is causing many parts of the ocean to become undersaturated with calcium carbonate minerals?
Q4) Research when did the Industrial Revolution occur?
Q5) What is the pH change in the ocean acidity levels since the Industrial Revolution? What percentage increase in acidity is that?
Q6) How many people world wide rely on food from the ocean as their primary source of protein?
Q7) When shelled organisms are at risk, what else is at risk?
Q8) Carbon dioxide dissolves in water and forms carbonate ions. This is represented in the equations:
water + carbon dioxide --> carbonate ion
Look at the image at the top. When additional carbon dioxide from pollution is dissolved in the water, it forms hydrogen carbonate ions. Subsequently, instead of the carbonate ions reacting with calcium ions to form coral reefs and sea shells, it is producing the acidic hydrogen carbonate ion.
How does increased carbon dioxide in the atmosphere therefore affect sea life populations?
Q9) What are some other environmental hazards resulting from increasing acidity levels?
Q10) Why is it therefore so important to reduce carbon dioxide emissions into the environment?
