the
spring equinox
. At this time,
the Sun’s rays fall directly on the
Equator. Days and nights are the
same length, 12 hours. (In the
Southern Hemisphere it is autumn.)
Winter
Winter begins with
the
winter solstice
. At this time,
the Sun’s rays fall directly on the
Tropic of Capricorn. This is when
the days are shortest and coldest in
the Northern Hemisphere.
Summer
Summer begins with
the
summer solstice
. At this time the
Sun’s rays fall directly on the Tropic
of Cancer. This is when the days are
longest and hottest in the Northern
hemisphere. (It is winter in the
Southern Hemisphere.)

the
autumn equinox
. At this time,
just as in spring, the Sun’s rays fall
