answers the question.
5) Due to human activities, more carbon dioxide is being released into the atmosphere than is
being removed. What happens to this extra carbon dioxide? Select all that apply.
A) Some of the carbon dioxide stays in the atmosphere which causes surface temperature

B) Approximately half of the extraneous carbon dioxide is being expelled into deep
space.
C) Much of the extraneous carbon dioxide is dissolved into the oceans where it is
causing acidification.
D) Trees and other plants have increased their rates of photosynthesis and are effectively
removing most of the extraneous carbon dioxide.
