Answer:
Forms of carbon differ in the oceans.
Explanation:
Two different primary types of carbon exist in the oceans.
- Carbonates - organisms in the ocean absorb carbon dioxide and produce carbonates CO₃²⁻. Calcium and magnesium ions combine with carbonates to form <u>calcium carbonate</u> that make up the bulk of corals and seashells plus <u>magnesium carbonate</u>.
When atmospheric CO₂ dissolves directly into the seawater, carbonic acid is produced, that reduces the pH of seawater.
One of the earth's precious diverse ecosystems comprises of coral reefs. Coral reefs' body is made up of calcium carbonate. However, calcium carbonate acts as a buffer. That's why, as pH decreases, the dissolution of calcium carbonate (corals structure and seashells) increases. It results in a massive extinction of coral ecosystem.
Hence, we should not disturb the balance of nature.
After studying the diagram that you posted above with the question and my own knowledge this is an easily answerable question.
Since I can't circle the answer in the book, I will tell you what to circle for the type of eclipse that may occur when the moon is located in position A.
You will need to circle the "solar eclipse." The reason why this type of eclipse may occur when the moon is at this particular position is because the shadow of the moon falls on the Earth during a solar eclipse. Another reason why is because the moon is aligned between the Sun and the earth.
