Question

most of the water vapor and carbon dioxide in earths atmosphere is found
a. in the upper part of the atmosphere
b. in a thick layer right in the middle of the atmosphere
c. in the lower part of the atmosphere
d. in a thin layer right in the middle of the atmosphere

Explanation:

The Earth's atmosphere has layers, and most water vapor and carbon dioxide are in the troposphere, which is the lower part of the atmosphere. The troposphere is closest to the Earth's surface, where weather occurs and where most of these gases accumulate due to their heavier nature and processes like evaporation and respiration near the surface. So option C is correct.

Answer:

C. in the lower part of the atmosphere
