Question

which of the following pairs of events appear to be linked? select one: a. increased atmospheric carbon dioxide and lower ph in the ocean b. melting glaciers and increased ph of the oceans c. increased sea levels and reduced atmospheric carbon dioxide d. increased atmospheric carbon dioxide and decreased temperature of earth

Explanation:

When atmospheric carbon - dioxide increases, more of it dissolves in the ocean. Carbon dioxide reacts with water in the ocean to form carbonic acid, which dissociates to release hydrogen ions, thus lowering the ocean's pH. Melting glaciers add fresh water to the ocean which does not increase the pH. Increased sea - levels are related to melting ice and thermal expansion, not reduced atmospheric carbon dioxide. Increased atmospheric carbon dioxide is a greenhouse gas that causes the Earth's temperature to rise, not decrease.

Answer:

A. increased atmospheric carbon dioxide and lower pH in the ocean
