Lake Ontario, one of the Great Lakes, usually receives heavy snowfall during the winter. Snow often falls after a cold air mass passes through the area. 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?

• 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.

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

The paths of two air masses, X and Y, are shown in the diagram below. Air mass X is a cold air mass. Air mass Y is a warm air mass. When the air masses meet, winter storms may be produced. Which of the following most likely contributes to the formation of these storms?

• Cold air mass X moves over warm air mass Y, and evaporation occurs.

• Warm air mass Y moves over cold air mass X, and condensation occurs.

• Cold air mass X mixes with warm air mass Y, and the overall temperature increases.

• Warm air mass Y mixes with cold air mass X, and the overall temperature decreases.
