Final answer:
The occurrence of the Sun on the summer solstice along a specific geographic feature in lands at the Tropic of Cancer.
Step-by-step explanation:
The subject of this question is Geography. The question is about the occurrence of a phenomenon along a specific geographic feature on the summer solstice.
On the summer solstice, the Sun appears at its highest point in the sky and is directly overhead at the Tropic of Cancer, which is located at 23.5° north latitude. This means that in lands along the Tropic of Cancer, the Sun may only occur directly overhead on the summer solstice.
For example, in places near Hawaii, which is close to 23.5° N latitude, the Sun would be directly overhead at noon on the summer solstice.
