This air mass tends to be colder than the lake water. Which of the following best explains why snow falls over the lake after the air mass passes over it?

Snow falls from clouds that form when rising water vapor from the lake is cooled by the air mass and condenses.

The air mass pushes clouds over the lake, and snow falls from the clouds.

Snow falls when sinking air from the air mass is warmed by the lake water.

The air mass cools the surface of the lake, causing condensation to occur and snow to fall.
