defining Equinox and Solstice an equinox
0:03
and a solstice are both key astronomical
0:05
events that Mark changes in Earth's
0:07
position relative to the Sun the
0:09
equinoxes occur when the Earth's axis is
0:12
not tilted toward or away from the Sun
0:14
resulting in nearly equal day and night
0:16
lengths the solstices happen when the
0:19
Earth's Tilt is most pronounced leading
0:21
to the longest or shortest days of the
0:25
year timing of the
0:27
events equinoxes occurred twice a year
0:30
once around March 20th or 21 the spring
0:33
or vernal equinox and Once Around
0:36
September 22nd or 23 The aunal Equinox
0:40
solstices also happen twice a year
0:43
around June 21st the summer solstice and
0:46
around December 21st the winter
0:50
solstice day and night
0:53
length during an equinox the day and
0:55
night are approximately equal in length
0:57
across the globe with both lasting about
1:00
12 hours on the other hand a solstice
1:03
results in extreme differences in day
1:05
length with the summer solstice having
1:07
the longest day of the year and the
1:08
winter solstice having the shortest
1:11
sun's position in the sky during the
1:13
Equinox the sun is directly above the
1:16
equator resulting in equal exposure to
1:18
sunlight in both hemispheres during the
1:21
solstice the Sun reaches its highest
1:23
point in the sky at noon during the
1:25
summer solstice or its lowest point
1:27
during the winter solstice depending on
1:29
the hemisphere
1:32
seasonal
1:33
changes equinoxes Mark the beginning of
1:36
the spring and Autumn Seasons
1:37
representing the transition to warmer or
1:39
cooler weather solstices Mark the start
1:42
of summer and winter signaling the peak
1:44
of warmth or the onset of cold depending
1:47
on the
1:49
hemisphere impact on
1:51
hemispheres in the northern hemisphere
1:54
the March Equinox signals the start of
1:56
spring and the September equinox signals
1:58
the start of autumn conversely the June
2:01
Solstice is the summer solstice in the
2:03
Northern Hemisphere and the December
2:05
Solstice is the winter solstice the
2:08
reverse occurs in the southern
2:11
hemisphere Earth's Tilt and orbit
2:14
equinoxes happen when the Earth's axis
2:17
is perpendicular to the sun's Rays
2:19
meaning there is no tilt toward or away
2:21
from the Sun solstices occur when
2:23
Earth's axial tilt is at its maximum
2:27
23.5° causing one hemisphere to be
2:29
tilted toward the sun and the other way
2:32
astronomical significance both events
2:35
are significant for astronomers and
2:37
meteorologists equinoxes help Define the
2:40
length of Seasons while solstices
2:42
provide reference points for the Earth's
2:43
Tilt and orbit which affects climate and
2:46
daylight patterns cultural and
2:48
historical importance equinoxes and
2:51
solstices have long been important in
2:53
various cultures often marking
2:55
agricultural Cycles are being celebrated
2:57
with festivals and rituals for example
2:59
example the summer solstice has been
3:02
historically celebrated in many cultures
3:04
as a time of abundance while the winter
3:06
solstice often represents renewal or
3:08
rebirth key difference day length and
3:11
Sun position the primary difference
3:13
between an equinox and a solstice lies
3:16
in the sun's position and the length of
3:17
day and night equinoxes feature equal
3:20
day and night lengths while solstices
3:22
result in the longest or shortest day of
3:24
the year depending on the hemisphere's
3:26
tilt toward or away from the Sun
