Question

why is noon the hottest part of the day?

Answer 1

Noon is the hottest time of the day because during the noon time the is right above us and the Rays of the sun fall directly.The direct Ray's of the sun are hotter than slanting days.

Answer 2

The hottest time of the day is around 3 p.m. Heat continues building up after noon, when the sun is highest in the sky, as long as more heat is arriving at the earth than leaving. By 3 p.m. or so, the sun is low enough in the sky for outgoing heat to be greater than incoming. Sometimes the hottest time is earlier because a weather system moves in with cool air early in the day.
