Question

question 72
the increase in carbon dioxide levels correlates with an increase in __.
a snow - covered areas.
b earth surface temperature.
c the ozone layer.
d el niño’s.
e volcanic activity.

Explanation:

Carbon dioxide is a greenhouse gas. An increase in greenhouse gases like CO₂ traps more heat, leading to a rise in Earth's surface temperature. Option A is incorrect as higher CO₂ (and temperature) would reduce snow - covered areas. Option C: Ozone layer is related to ozone (O₃) and different factors, not directly CO₂ levels. Option D: El Niño is a climate pattern related to ocean - atmosphere interactions in the Pacific, not directly correlated with CO₂ increase. Option E: Volcanic activity releases CO₂ but the question is about CO₂ increase correlating with something, and volcanic activity isn't the direct correlation here. So the correct correlation is with Earth surface temperature.

Answer:

B. Earth surface temperature.
