This phenomenon is most marked in places exactly where the soil, strongly heated from the solar rays, raises the temperature of your reduced layers of your environment, lowering its density and growing the pace in the wave fronts that travel close to the ground. Thus, the portions of the wavefront in the vicinity of the bottom move with increased v
