Question

question 20 of 25 which of these has a warming effect on earth? a. rising carbon dioxide levels spur plant growth, causing increased carbon dioxide absorption. b. earths oceans absorb carbon dioxide from the atmosphere. c. as snow and ice melt, the underlying surfaces absorb more solar radiation. d. more evaporation of water due to warmer temperatures causes low, thick clouds to form.

Explanation:

• Option A: Increased plant growth due to rising CO2 levels leads to more CO2 absorption, which is a cooling - related process.
• Option B: Oceans absorbing CO2 from the atmosphere is a carbon - sequestration process that helps cool the Earth.
• Option C: When snow and ice melt, the darker underlying surfaces have a lower albedo and absorb more solar radiation, leading to warming.
• Option D: Formation of low, thick clouds due to evaporation can have a cooling effect as they reflect solar radiation back into space.

Answer:

C. As snow and ice melt, the underlying surfaces absorb more solar radiation.
