How the climatic zones of the planet influence rhythmic and seasonal changes
Explanation:
The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet.

This is the start of astronomical summer in the northern hemisphere and winter in the southern hemisphere.
