How does the concentration (amount) of carbon dioxide in the affect climate? A. As carbon dioxide concentrations increase, temperatures decrease.
B. As carbon dioxide concentrations increase, temperatures increase.
C. Carbon dioxide concentrations have no affect on climate.
D. As carbon dioxide concentrations increase, temperatures become more random.

A

Explanation:

When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
