What does the graph of atmospheric Carbon Dioxide tell us? The graph of atmospheric carbon dioxide tell us that the levels of CO2 is steadily rising
pH Scale: where do some common items fall on the pH ? Screenshot Taking below
Ocean pH: How might it change? change from 8.2 to 8.1 on the pH scale is a ___30__ % increase in acidity.
Carbon in the Water: Explain what happens to Carbon in ocean water.
When the carbon combines with water molecules it becomes carbonic acid , which means that ocean acidity increase.
Exploring Carbon Levels and Effects: Look over the interactive and describe what happens
at each of the levels:
Scenario 1: Optimistic
Every 10 years the pH of the ocean water decreases .2%, on the other hand CO2 increases.
Scenario 2: Middle Ground
Every 10 years the pH of the ocean water .2%, on the other hand CO2 increase by 1.6
Scenario 3: Pessimistic
Every 10 years the pH of the ocean decreases 2% , and the CO2 increases.
Diversity of Life in the Sea: Sort each of the organisms into Calcifiers or Non-Calcifiers. Screenshot Below
Describe the life cycle of Echinoderms and explain why they are so sensitive to changes in pH.
at first they start as larva then they grow becoming of hat its called urchin lava. After this larva starts goring it start developing some juvenile structures, and right after the skeleton developed to its mature style it becomes metamorphosis.
