You can set up an experiment in your yard to track the shadows the sun throws on an equinox. Put a stick (aka, a gnomon) in the ground or through a piece of cardboard and then mark the tip of its shadow throughout the day. It will trace a perfectly straight line. Other times of the year it will trace a frowny face during northern hemisphere summer and a smiley face during northern hemisphere winter. A straight line will happen only on an equinox.
Thank you so much Nat Geo! I always love your videos!
this was so cool to learn about , ty

Today's the day of autumnal equinox
Let's see what's happens today equal day and night 🤨 in India
VERY GOOD
nice soundtrack
You should mention "only in 4 seasons continents", because I live with 12hrs day & 12hrs night everyday, where equinox means hotter than normal..
nope
"only"? The only place wheres theres 12hrs day and night is equator :D so he described how it works for like 95% countries on our planet.
Nice
Thanks again yesterday
Good afternoon 🌅
Nice music
What was the music name?
Yap today in my country Indonesia has equinox, nothing special but the light is very bright
Nice music
Wow!!
Thanks for watching and learning with us!
Whoa
@Nova S True
September equinox tonight 💖
Well, now I know when to use the "vernal equinox" excuse for leg day.
dddxtdrfced was a great time of my week with a good woman with the kids I
Ok, we were doing just fine until 0:58 the solstice term came up. Whats that? They mean the same? Ok, we'll keep digging for complete knowledge. This vid is nice though! 2 thumbs up! :)
*solstices are the longest day and the shortest day.. Mainly summer solstice have long day hours and short night hours, and winter solstice have short day hours and long night hours...*
Ok, but where is captain Yami??
Welcome
Wow!! That's the thing that cool I ever heard.. so cool very cool. So so so so very cool...
Can’t wait to post the Angkor Equinox when the sun ☀️ rises just over the top of Angkor Wat central tower soon. Bear with Sam Inspire Angkor from 21 March 2021 onward!
It is actually one of Skrillex's track.
Interesting😮
Stay curious!
hello
I'm not sure about the signifegence of the equinox signaling of 'the changing seasons'.
I guess from historical times they would be near to going into the cold, dark months and coming out of them.
Anyone else watching the day before autumnal equinox?
It's a Warframe! *gets slapped*
Nicky Park exactly the reason I came here lol
Aha, that was my exact first thought too. At least I now know the meaning behind one of my mains' name.
It's funny I just assembled an equinox.
My god how many times do I have to put you down Stalker (joke btw)
CÜRER HOCAMA SELAMLAR
I didn't know this happens.
Thanks for watching and learning with us!
Yami dimension slash
Subhana alaah it's amazing alaahu akbar
we have a lesson about this in our school recently
In September 22 it's called a autumnul equinox..
You know that people live in the southern hemisphere right? It's sad we don't ever seem to get more that the quickest mention..🙄 Still liked you video nation geographic but can you please include us next time?
0:08 It should be "They occur twice in one revolution of a planet around the sun" Isn't it?
Autumnal Equinox.
Happy AE everyone!
@@IamJay no
I'd like to hear from Flat-eathers the explanation of this. I'm sure they have one.
Scientists use a giant flashlight to make us think we have equal days!
@@XxXxxModeratorxxXxX : Not just any scientists. Only those working for NASA.

Is that our new home?
What's wrong with Autumn? I remember when people used to call Autumn Autumn, instead of Fall. Choices of words affect people. So if you are in the middle of Fall, your subconscious mind could interpret that as you being in the middle of your fall, as in down fall.
In May 20 it's called vernal equinox..
🥰
On every planet? What about Uranus that one is rolling on his side...
Yes. Even on Uranus, the Sun incides perpendicular to its surface in its Equator twice a "Uranus year". Time between equinoxes is 42 Earth years approximately.
As above, so below.
It's actually a blender's brand
equinox of fall and equinox of spring
Now
it’s the name of a dance club here
😂

دن اور رات کا برابر ہونا ہے۔۔۔۔
so whats a solstice?
@Kit Canyon its when the sun is at the tropics. summer solstice is when the sun is at the tropic of cancer June 21, winter solstice is when the sun is circling above the tropic of Capricorn, December 21. in the winter the sun and moon move faster then in the summer, you can observe it , especially if you have a good camera. make some videos in June and in December and compare.
สร้างสรรค์มาก😊😊😊🤪🤪🤪
Vernal equinox = Skip legday
Web consortium agreement with AMUN
NOT AS YET
Actually it’s the equilux that has equal day and night, not the equinox
It’s EQUINOX .check back your facts
@@louisaanne5614 thanks - but go ahead and check your facts. A quick google search will suffice. Equal day and night is equilux- equinox is approximately equal but not exactly equal. Look it up. Much love

There 2 Sphinx in Egypt!!!!
Really tho
Real LifeNCali Egypt gods were based on astronomy
This video is so busy. Take this one minute and 26 seconds to teach with clarity and simplicity. There's no need for fancy graphics with all sorts of movement on the screen at once. The only movement that matters is the earth revolving around the sun while maintaining its axis of rotation facing in the same direction and always at 23.4 degrees.
My teacher send this video to my WhatsApp my school group to see what is the difference between day and night

I'm here because of captain Yami black clover lol🙂
National geographic couldn't afford a narrator?
Why would every planet have this 2x per year?
They would need to be tilted, for that. Otherwise they would constantly be perpendicular to the Sun, not just 2x year
Well, most planets do have some tilt although mercury’s is pretty much zero.
not twice in a year of every planet of solar system. It is my opinion earth revolves round sun in 1 year. revolution time varies for other planets of solar system. also the angle planet rotates. I have n't read fully.
0:11
what about the southern hemisphere
Equinoxes happen for the entire globe.
@@eMBO_Gaming Yeah ik but this video only talked about the northern but not the southern hemisphere
@@ninjapirate123 But it still looks the same for both hemispheres, as during the equinox the Sun shines perpendicular to the equator. That's the entire point of the equinox in the first place.
@@eMBO_Gaming So it's opposite
@@ninjapirate123 what part would be opposite?
But are you talking about the seasons being different?
Spoiler: Its a Chevy
Deym Chevy Equinox 😂
10TH like xD! ;D
it means the weather is changing' duh thats why the equinox like who ever does'nt know this watch this then go away

A car brand

Don't believe it. The equilux is what you're looking for.

Everything is so calculated in the Universe and some people still say Universe is a result of random explosion.
Its a sign that the world will end
if I had to look up equinox, why would you think I would know what solstice means? I'm not even gonna look it up
an overpriced gym
this video made me hate school
No, National Geographic, the first phrase you put in this video is not accurate to describe an equinox. Equinoxes are the moments of the year when the Sun rays incide perpendicular to Earth surface in the Equator. This causes that the number of daylight hours are approximately the same in all the places of the Earth.
God is a great God, thee maker and the creater of this great Earth. Praise the name on the Lord.
