question 2 of 10
overall, how has the climate changed during the cenozoic era?

a. it has warmed up.

b. it has become more humid.

c. it has cooled.

Explanation:

The Cenozoic era is known for a general cooling trend (after initial warming in early Cenozoic, overall long - term trend in Cenozoic is cooling, with glaciations etc.). Option A is incorrect as the overall Cenozoic trend isn't warming up. Option B, humidity isn't the main overall climate change of Cenozoic. Option D is wrong as climate did change. So the correct answer is related to cooling.

Answer:

C. It has cooled.
