• Because we put the clocks back an hour for that reason.
  • because the sun moves closer to where you are in the summer, so more daylight.
  • only in the northern hemisphere - in the south, the seasons are reversed we're outsourcing our daylight during the winter during the summer, we're outsourcing our darkness
  • "The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. 1). This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons. It is easy to observe the effect of the axis tilt from the change in day length, and altitude of the Sun at noon (the culmination of the Sun), during a year." "Fig. 1 This is a diagram of the seasons, regardless of the time of day (i.e. the Earth's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter. In addition to the density of incident light, the dissipation of light in the atmosphere is greater when it falls at a shallow angle."
