Question: Keeping the observation point and the target fixed, the near-sea surface air is heated by sunlight until its temperature exceeds that of the layer above (other conditions approximately unchanged). What change is most likely in the target’s apparent vertical position at a distance?
A. Rises significantly
B. Drops noticeably, possibly even disappearing from view
C. Remains roughly unchanged
D. Splits into multiple images
Clues:
1. A large body of water is visible in the lower half of the image.
2. A thick, white layer of fog or cloud is present horizontally across the middle of the image, above the water.
3. The top section of a building with a grid-like structure is seen protruding from the top of the fog layer.
4. The lower part of the building is not visible, as it is obscured by the fog.
