What do the words Solstice and Equinox mean? How are they related to the position of Earth's axis?

Answer by  eatwrite (1559)

When something is equal it is equinox and close to the equator. When things are not equal and are far away, they are solstice. Look at the stars and the planets.

Solstice ("Sun stands still") refers to when the days get shorter and longer: respectively December and June 21st An equinox occurs when the Sun's directly over the Earth's equator (1st days of Spring and Fall). One effect is that on an equinox, daylight and nighttime are equally long everywhere on Earth. "equinox" meaning "equal night."
