High school geography topics that are often tested in 24 solar terms.

Twenty-four solar terms are: spring rain surprises spring and clear valley days, summer is full and summer is hot, autumn dew, autumn cold and frost fall, and winter snow is snowy.

Among the 24 solar terms, vernal equinox, autumnal equinox, summer solstice and winter solstice often appear in geography topics in senior high schools.

The location of the direct point of the sun, the distribution and change of the height of the sun at noon, and the distribution and change of the length of day and night on these four special dates. Other solar terms are rarely involved.
