Question

Which of the following is least likely to occur if the concentration of greenhouse gases in our atmosphere continues to increase?

A. An increase in ocean acidification
B. An increase in melting rates of glaciers
C. An increase in average global temperatures
D. An increase in the thickness of the ozone layer

Answer 1

If greenhouse gas concentration continues to increase, the least likely occurrence would be an increase in the thickness of the ozone layer.

Step-by-step explanation:

If the concentration of greenhouse gases in our atmosphere continues to increase, the least likely to occur would be an increase in the thickness of the ozone layer (option D). Greenhouse gases such as carbon dioxide and methane contribute to the greenhouse effect, trapping heat in the earth's atmosphere and leading to global warming.

This causes a variety of effects such as an increase in average global temperatures (option C), an increase in ocean acidification (option A), and an increase in melting rates of glaciers (option B).
