Lionel uses a model that includes the atmosphere and sunlight to predict earth’s temperatures. in this model, why does increasing the levels of carbon dioxide in the atmosphere cause temperatures to increase?

a. sunlight passes through carbon dioxide.
b. heat is trapped by carbon dioxide.
c. carbon dioxide generates heat.
d. carbon dioxide reacts with water to release heat.

The correct answer is B. Heat is trapped by carbon dioxide.

Explanation

Carbon dioxide is a greenhouse gas, this means that this gas causes the sun's rays to get trapped in the Earth's atmosphere after they pass through it. The greenhouse effect is the concentration of temperature in the atmosphere without leaving because greenhouse gases prevent the release of radiation. According to the above, if Lionel increases the amount of carbon dioxide, the temperature will increase because carbon dioxide will prevent its exit. So, the correct answer is C. Carbon dioxide generates heat.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

a = executive branch; b = judicial branch
