Question

match each gas with how it naturally enters the atmosphere: co₂ (carbon dioxide) ch₄ (methane) noₓ (nitrogen oxides) h₂o (water vapor) a. evaporation in the water cycle b. cows burping c. lightning striking the soil d. cellular respiration

Explanation:

Cellular respiration in living organisms releases carbon - dioxide into the atmosphere. Cows are ruminants and their burping releases methane. Lightning striking the soil causes chemical reactions that release nitrogen oxides. Evaporation in the water cycle turns liquid water into water vapor.

Answer:

CO₂ (carbon dioxide) - d. Cellular Respiration
CH₄ (methane) - b. Cows burping
NOₓ (nitrogen oxides) - c. Lightning striking the soil
H₂O (water vapor) - a. Evaporation in the water cycle
