Identify where the sun's rays strike earth most directly and least directly

- - Depending on the time of the year, the sun's rays strike Earth

most directly somewhere between the Tropic of Cancer and the

Tropic of Capricorn.

That's a belt around the Earth's "middle" called the "Tropic Zone".

The equator is in the middle of it, the Tropic of Cancer is 23.5° North

of the equator, and the Tropic of Capricorn is 23.5° degrees South of it.

The sun's rays can never be totally direct, straight down onto the Earth's

surface, anywhere outside this belt.

- - The sun's rays strike Earth least directly wherever, and whenever,

the sun is setting.
