Question

how does the proportion of carbon dioxide in the atmosphere differ between earth and venus? (1 point)
venuss atmosphere has a higher proportion of carbon dioxide than earths, so greenhouse gasses trap more heat.

venuss atmosphere has a lower proportion of carbon dioxide than earths, so greenhouse gasses trap more heat.

Explanation:

Venus has a thick atmosphere mostly composed of carbon - dioxide (about 96.5%). Earth's atmosphere has only about 0.04% carbon - dioxide. More carbon - dioxide means more heat is trapped by the greenhouse effect.

Answer:

Venus's atmosphere has a higher proportion of carbon dioxide than Earth's, so greenhouse gasses trap more heat.
