Tropical Zone

Real World Example

Imagine trying to keep your living room warm during the winter when your heater only covers the center of the room. Just like the heater warms the area closest to it most effectively, the tropical zone, stretching 23º north and south of the equator, is consistently warm because it is closest to the sun’s direct rays. In this analogy, the heater represents the sun, the living room is akin to Earth, and the warmest part of the room, right in the middle, corresponds to the tropical zone where the sun’s heat is most concentrated.
