Question

a scientist measured an increase in nitrous oxide in the atmosphere. this increase would result in
an increase in the greenhouse effect.
a decrease in the greenhouse effect.
no change in the greenhouse effect.
a stabilization of the greenhouse effect.

Explanation:

Nitrous oxide (\(N_2O\)) is a greenhouse gas. Greenhouse gases trap heat in the atmosphere, and an increase in their concentration (like the increase in nitrous oxide here) leads to a stronger greenhouse effect, meaning more heat is trapped, so the greenhouse effect increases.

Answer:

an increase in the greenhouse effect
