What is the connection between the curves shape of earth sunlight and Earths 3 main climate zones?

Answer 1

The curvature of the Earth affects how sunlight is distributed across its surface, resulting in variations in temperature and climate. Sunlight strikes the equatorial regions more directly, leading to warmer temperatures and the tropical climate zone. In contrast, sunlight hits the polar regions at a slant, spreading its energy over a larger area, which results in colder temperatures and the polar climate zone. This differential heating creates the three main climate zones: tropical, temperate, and polar.
