Had to watch this for a science assignment gang ↓

I hope everyone who participated making this video are fine and dandy 10 years afterwards! It was a pleasure to watch & learn ;)

Seriously , this is one of the best explained videos of this topic...Thanks MIT

"And there's so much more to talk about, did you know that the earth-" "Ya know, I actually think I'm good for now." Nailed it 😂😂

This is the absolute best and clearest to visualize and understand explanation on this that you could ever watch. Thanks!

I unironically didn't know this and I'm 30. Very nice explanation. Also explains why equatorial places remain warm throughout the year.

Summer🥰 Summe😇 Summ🙂 Sum🤨 Su😒 S🙁 Sc😒 Sch😕 Scho☹️ Schoo😣 School😭

I'm 28 years and I didn't know that the angle was responsible...yikes. Thank you for the video

i was forced to watch this cus of online school

I cannot stress how glad I am that I found this video. It explains things so well!! Thank you for making it

Dude my whole 30 years of existence I had no idea about this. I thought the whole world was winter and summer at the same time. This is fascinating. I still have so much to learn.

thank you for making this, easy to explain

I use a flashlight to explain the seasons to my students as well. This is something that while some people will understand from a written explanation, the majority of people will need something visual to really fully grasp it. So I explain it verbally and then demonstrate the concept with a flashlight and I suddenly hear one student after another say "oh, now I get it." It's great.

This is a perfect explanation on seasons of the year; thank you very much... I will recommend the video to my student teachers, hope is free for using it in teaching and learning

I’ve known about the tilt for forever but never knew about the spread out energy vs concentrated energy. I just assumed it was warmer because the tilted hemisphere was technically closer to the sun. But this makes way more sense. Thanks!

Best explanation so far, it's that "lean in part" (how I choose to word it to understand it better lol) of the earth that gets the most direct sunlight making that area experience summer, the rest of the sunlight diffuses over the rest of the area making them experience winter, got it! :)

Awesome explanation - U kept it very simple and the message is passed very easily. How I wish I had a teacher like you when I was young. I would have been a scientist now

The axis does actually wiggle around a little in two different ways it just takes along time to do it, The axis varies from an approx. minimum tilt of 21.5 deg. to 24.5 deg. over a 41,000 year period. The second is axial precession the movement of the rotational axis of an astronomical body, whereby the axis slowly traces out a cone, Earth goes through one complete precessional cycle in a period of approx. 26,000 years or 1deg. every 72 years, ATM the north star is Polaris, The north star has changed over the past 11,000 years, and in another 11,000 years it will switch back to Vega. The north star changes because of precession and is slightly influenced by the change in the angle of the Earth's tilt.

POV: you where forced to come and watch this for planet orb/earth since thing

Thanks for this, I had to watch a hundred videos on this subject before yours finally actually demonstrated it properly. Nice work!

This cleared up a few misconceptions of mine, Greatly appreciated.

POV: half of these views are for online school.

This video is by far the clearest and most charming version of this explanation I have seen. And you explain the science concepts so memorably. Perfect for our students--we watched it several times, thank you!

Thank you! this really helps me to represent a simulation in my Earth Science class!!!

I agree! I didn't know the real answer, the answer of the sun being further away is something I might of thought of myself. I'm taking an Astronomy class and learning most of this stuff for the first time! I never realized exactly why different things happened the way they did. I feel its actually pretty important to know, as citizens of this planet Earth! Thank you for these videos, I found them helpful for Biology as well. :-)

A very well designed video. Great work guys!

Amazing clarity of the season concept. Thanks.

my science teacher linked me to this video. I learned things i didn't know about the seasons!! Thanks a lot!!!! :DD

Hey you guys are awesome seriously. Thankyou for explaining in a very simple way.

Thinking actually hurts my brain

As an adult I appreciate this video! Trying to gather a game plan to teach revolution to my child and was stumped on the earth's tilt and how that contributes to the seasons if we are only moving two ways (around the sun and spinning ourselves) how could that possibly create seasons when each side of the earth is always facing the sun once a day. 2:30 into the video explained it so concisely. Me and the kids will enjoy this video. Great ideas on here to demonstrate and gave me a cool idea to make a globe with paper mache with my kids.

I'm 48 years old, and despite reading many books and watching many videos and knowing it was the tilt that caused the seasons, I was unable to visualise it properly in my head until seeing this video. I think it was the bit where you moved the Earth from one side to the other - I was always trying to visualise the Earth rotating as it orbited the Sun, and mentally I couldn't sustain the correct tilt as I did that. This model solved that for me. Thanks!

I love Spring. Spring is the season of life. No more the bare wands that told of winter's magic, here come the green flags, the parade of spring in bright bloom. The chorus of the skies has called forth the promise of the earth and sunshine combined. These weeks will be as a developing photograph - the colours deepening with the richness of the season. The early morning sunlight, soft and diffuse, gives way to the first strong rays of the day, the ones that bring true warmth. In this light, water evaporates in slow waves, waves that eddy in the gentle breeze, flowing upward to white-puffed clouds, ships of white in the blue above. The opera from the trees becomes all the more powerful, as if these golden rays are their conductor's wand, and together they are the song that calls forth the spring. There is a playfulness in nature, in the skies, woodland and soil. The time of plenty is coming and the joy of coming abundance energizes the air. In rain or shine, there is a new warmth, inviting the lips to smile. The greenness of the grass is soon to be echoed by the trees, while the flowers promise their rainbow garland to our Earth. (Thanks for reading)

What a great video, very well explained. Now I can understand that why New Zealand is cold during July and opposite in Canada. Sun is very bright and scorching in New Zealand also can be reason due to this tilt 23.5 degrees

Love this video! I'm a homeschooled and always looking for great resources. This definitely helped my little grasp the concept. Thanks!

One fine day I decided I better learn why we have seasons before our grandkids start asking and have gone through several videos many with fancy videos of winter, summer, outer space, etc. This is by far the best - it uses simple ideas to explain something not that easy to grasp intuitively and does it with panache and humour.

This is just the perfect video. Thank you so much for all the efforts you guys have put into this. I don't think anyone could have explained it better than this.

I'm 23 and I didn't know that, just some days before I found out that it's the tilt that causes seasons and not the elliptical orbit path but at that time I didn't exactly figure out how that would be happening I just accepted it as a science fact but after watching this video I have finally understood it and I can teach others as well. Thank you for the video. Happy New Year 2016

wonderfully made! My class will enjoy this. Thank you!

Thank you for explaining that info. I have always wondered what caused winter/summer. Much appreciated.

Great job! Settled an argument a friend and I was having. Lol

All these people saying “Like if you are watching this for science class” No dur we’re watching this for science class. Who watches this stuff for fun?!?!?!

Yesterday i learned this in the Netflix series, Our Universe, i had to understand it completely so i came here, thank you for making me understand better. ❤

Thanks, great info with a good demonstration

1:16 is what was taught to me at school...we had a junior teacher for geography that year

Great. Exactly how I explain it in my classrooms and unfortunately, as already mentioned, this is the only video I've seem here that explains it accurately. The only suggestion I would make is yo add something I do to help explain direct vs indirect light. I shine a flashlight directly at the students' faces, and then indirectly, glancing from the side. I think it helps then understand the intensity if direct rays vs indirect rays. Otherwise, great video. Thank you for the refreshing accuracy

Wow this video makes it so simple to understand thanks so much!

That torch example is what made me understand. Thank you.

Hahahaha this video is besttttt ever video 😂😂 .....we understand everything with funny ways and that's important 🤘🤘🤘 thanks for the videos ❤❤❤❤❤❤

that is soooo reason able. it makes sense too

Awsome video! Never heard such a clear explanation! You are great, guys! God bless!

This is a very well put video! Thank you.

I watched this for my summer college class and I would never watch it on my own gang

Finally i got the simple and easy to understand explanation with every simple thing covered which may be difficult for some low IQ students like me

Always wondered this and only just thought about yourubeing it. Such a brilliant explanation and simple explanation thank you

THANK YOU. I was about to blow my brains out trying to understand (for my astronomy class) how the hell the tilt is toward or away from the sun. 2:45-3:05 was the missing piece that wasn't explained. Thank you sososososo much.

Yeh but the sun would be further away in summer & the angle of light rays would be same angle at times as in winter. should it not be colder when sun goes down in summer when same angle of light in winter.

Omg this actually was the best possible answer i could have gotten to my question. Cheers

This was fun to watch! Thank you :D

This is really helpful to my assignment, thank you so much cause i really understand why we have a tilt in seasons and once again THANK YOU so much.❤️❤️❤️❤️

Finally...I watched about 6 videos about the seasons on Earth on youtube and it's the first one I fully understood . My God.......

Another interesting thing about the tilt is that it perfectly explains the "midnight sun" in _Antarctica_, where the sun goes _all the way around the horizon, but doesn't dip below it._ This totally disproves the flat earth model, of course, because how could something go *behind you* if it orbits within the "ice wall" you are standing in? (It would move in a left to right, right to left motion in front of you if you were facing north). The only "explanation" they have that I've seen is to just call all videos of the midnight sun in Antarctica "fake" (like their answer to everything else that they can't explain, such as the many non-NASA pictures of the earth from space). None of them have the confidence to actually go there themselves, like the 30,000+ tourists who go to Antarctica every year. But, I'm sure _they_ are all in on the conspiracy as well.... JW3HH

Now, that was mighty well explained. I didn't have to stop and think for a second.

one of the best ever video made on this topic. thank you.

All this time I thought the earth rotated on it's axis, I was told wrong as a kid, and never learned right. I feel dumb right now. And I got a 5 on my calculus ap exam, so no excuse for my mathematical stupidity. Sigh. I never realized the axis tilt is the same, just it's relation to the sun is different when on the opposite side.

thank you im finally starting to understand, i had no idea what my teacher was talking about and now im starting to get it

Very well illustrated. Great video. Keep up the great work 👍👍

Great, good explanation!. I've heard about the tilt of Earth but had never really understood what way this affects the temperature.

cant believe I only learned this after being alive for 32 years

Very helpful for my quiz tomorrow, thank you so much.

Brilliant. I loved watching this

It is explained in the most easiest and perfect way possible.

I need this video to show it to my flat earther friend lmao.

I FINNALLY KNOW.. SCIENCE ROCKS!!!!

Well done guys, great video and narration

totally awesome video! entertaining and informative.

Super!

WoW, finally i understood it. It's a rare day when i am able understand. So, now in happiness , i m going to order pizza. . . . .. . But, I can't because a nice Pizza in India is very expensive. And i am poor by heart. So, i am just going to play WoT Blitz and ruin my future.

was very very helpful and cleared a lot of wrong information that I had. thanks!

thanks a lot.with the help of this video i undersood seasonal changes first time in my life.i was always confused on seasonal changes

The latest such report, has caused a stir by revealing that just 74% of Americans know the Earth revolves around the sun. :P

since when do bisons jump across the ocean

Things I think about while I’m sitting on the 🚽 Thank you for answering my question 🙌🏼

Thanks for the Video, very simple & easily understandable

very very good explanation that i understand 80 % ., but still 20%confusion

Why the earth have a tilt in a first place?

Wow l totally understand.... thank you so much for wonderful information.

BEST Description for youth so far!!!! Thanks!!!!

Who’s hear from mr Nelson class

in school they actually taught the eclipse theory. I later found out they where wrong lol

Very well explained. Thank you

thank you for a good video could you explain how sun raise from south then set in the north

Perfect

Can I watch ONE geography video on KZfaq without some moron commenting about that ridiculous flat earth theory?

thanks, this is the best of i've watched.

Man. Thanks. I got it now...simple and neat....work..

thank you now I can see a flat earth as the only true possibility

so boring

I love this!! My science teacher gave this to us!

This is greate I am glad that I find this Video Thank you
