quiz
question 3 of 10
nitrogen makes its way to the ground via ______.
choose one option
a meteor impacts
b volcanic eruptions
c lightning strikes
d precipitation

Explanation:

In the nitrogen cycle, nitrogen in the atmosphere (like nitrogen oxides formed via lightning or other processes) can be incorporated into compounds that fall to the ground through precipitation (rain, snow, etc.). Meteor impacts are not a main way nitrogen reaches the ground. Volcanic eruptions release some gases but not the primary way for atmospheric nitrogen to the ground. Lightning helps fix nitrogen into compounds, but the actual transfer to the ground is via precipitation. So the correct option is D.

Answer:

D. precipitation
