Why is winter colder than summer?

    It has to do with the combined factors of the tilt of the earth on its axis and its current location in in its elliptical orbit.  As the earth’s position relative to the sun shifts, different parts are exposed to stronger solar radiation for longer periods of time (for example the Northern Hemisphere during June) while other parts receive less sun for less time causing winter (i.e. the Southern Hemisphere during June).   When one of the hemispheres is tilted towards the sun, the radiation it receives is much more direct than when the hemisphere is tilted away from the sun.   You can see how the seasons relate to the orbit and tilt in this drawing:
