2. The temperature of Earth’s surface would decrease because more heat would escape into space.
3. Venus's atmosphere has a higher proportion of carbon dioxide than Earth's, so greenhouse gases trap more heat.

about 78 percent
2.If the proportion of carbon dioxide in Earth’s atmosphere decreased significantly but the amount of atmosphere and the reflective properties of the atmosphere did not change, which effect would most likely occur?(1 point)
Responses
The temperature of Earth’s surface would decrease because more heat would escape into space.
The temperature of Earth’s surface would increase because more heat would be trapped by the atmosphere.
The temperature of Earth’s surface would increase because more solar energy would reach Earth.
The temperature of Earth’s surface would decrease because less solar energy would reach Earth.
3.How does the proportion of carbon dioxide in the atmosphere differ between Earth and Venus? (1 point)
Responses
Venus's atmosphere has a higher proportion of carbon dioxide than Earth's, so greenhouse gasses trap more heat.
Venus's atmosphere has a higher proportion of carbon dioxide than Earth's, so greenhouse gasses trap less heat.
Venus's atmosphere has a lower proportion of carbon dioxide than Earth's, so greenhouse gasses trap less heat.
Venus's atmosphere has a lower proportion of carbon dioxide than Earth's, so greenhouse gasses trap more heat.
