Answer
The air near the lake will be warmer than the air farther from the lake. Since warm air tends to rise while cool air tends to fall, the area near the lake will have a lower air pressure than the area farther from the lake. Therefore, at night, the breeze tends to blow toward the lake.
Work Step by Step
During a daily cycle, the water temperature changes much less than the air temperature. At night, the temperature of the air is normally cooler than the water temperature. Therefore the air near the lake will be warmer than the air farther from the lake. Since warm air tends to rise while cool air tends to fall, the area near the lake will have a lower air pressure than the area farther from the lake. Therefore, at night, the breeze tends to blow toward the lake.
