What are some physics trivia questions?

Answer 1

What effect is more responsible for the changing of the seasons, most notably, what is responsible for the climatic difference between summer and winter?

Is it because the earth is closer or farther away from the sun at different, recurring times of the year? Or is it due to the angular tilt of the earth on its axis, in relation to the sun, at different times of the year?

A:

The earth is actually closer to the sun on average during the winter than in the summer. This is almost counterintuitive. However the tilt of the earth, is what makes the geography colder, winter-ish, because the light from the sun become less direct, creating a wider, longer beam of light. Light from flashlight beam that is directed perpendicularly (at 90 degrees) on a projection screen with create a beam of greatest luminosity or light intensity or power. However when lowering the elbow and angling the light at a smaller angle like 45 degrees, the beam changes from circular to an oblong line of the same width, but of less intensity or brightness than the circular projection. This is analogous to the change in seasonal temperatures during the earth's annual cycles, or what we call our seasons.
