Solution
The higher latitudes near the north and south poles experience cooler temperatures because the Sun's rays are oblique to the surface.
Here's why:
-
The Earth is a sphere, so the Sun's rays don't hit all parts of the Earth at the same angle.
-
At the equator, the Sun's rays hit the Earth directly (at a 90-degree angle). This direct sunlight is concentrated in a small area, so it's very warm.
-
At the poles, the Sun's rays hit the Earth at an oblique angle (less than 90 degrees). This means the sunlight is spread out over a larger area, so it's less intense and the temperature is cooler.
-
Additionally, the Sun's rays have to pass through more of the Earth's atmosphere at the poles than at the equator. The atmosphere absorbs some of the Sun's heat, so less of it reaches the surface at the poles.
-
Therefore, the main reason for cooler temperatures at the poles is that the Sun's rays are oblique to the surface.
