If carbon dioxide, methane, and water vapor were not in the atmosphere, then a. the earth's surface would be much warmer than it is. b. the weather and climate of planet earth would not be affected. c. the organisms currently living on earth's surface would find it easier to survive. d. the earth's surface would be much colder than it is.

D. The Earth's surface would be much colder than it is.

This is because warm temperatures and high levels of atmospheric carbon dioxide happen at about the same time. So if atmospheric carbon dioxide concentrations double warm up by between 2 and 4.5 degrees Celsius. On the other hand, water vapor promotes, as the greatest contributor, to the Earth’s greenhouse effect. In this way, if carbon dioxide, methane, and water vapor were not in the atmosphere, then it's obvious that the Earth's surface would be much colder than it is.

7 - 9 = -2

reversed:

-2 + 9 = 7

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
