Season p.384 Most locations on earth experience seasons, patterns of temperature changes and other weather trends over the course of the year.

Equinox p.384 At an equinox sunlight shines equally on the northern and southern hemispheres.

solstice p.384 At a solstice the area of sunlight is at maximum in one hemisphere and a minimum in the other hemisphere.
