How can it be summer in North America and winter in Australia at the same time?! License: Creative Commons BY-NC-SA More information at k12videos.mit.e...
Meir Ustayev you're more of a loser if you're watching it not for a science assessment it means you're just watching a science video in your free time.
@@williammccallum7552 I mean both of you are incorrect, it is a matter of preference. But he started the argument so I think he should stfu and get back to the cellar.
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
Pure bull shit. Even if the earth was not tilted, according to their theory, the rays would still hit the same way. They didn't even consider the rays from the sun fanning out vs the rays being parallel... If they claim the earth is a sphere whether it is tilted or not, it will still be a sphere. So seasons are definitely not due to the proposed tilt.
KingOne look buddy you can go online on meteorology websites there you’ll find very deep explanation if u can’t find it ask again I’ll write you a nice explanation ? U might wanna consider studying though that might help u aswell.
LOL HA-HA EARTH DOESN'T TILT BROO EARTH IS STILL STATIONARY AND FLAT WITH A DOME ON TOP . RESEARCH FLAT EARTH BROO AT THE END OF THE AGE THE WORLD SHALL WOBBLE LIKE A DRUNKARD BROO *GLUG GLUG GLUG* IMMA WOBBLE THIS WIGGLY WORLD OMG A;LSFJA;WEFJOAWEJOAJEW
I’m 38 and I just got it lol the reason being I’m now interested to know before I was forced to so I didn’t pay attention also I’m at the equator and it’s cold as hell and it’s raining while it’s hot in Europe
@@daemoniumvenator7099 Well, its not like people search this up or need to know about it. I mean, counting to 10 in Japanese is common knowledge is Japan. Its something you most likely learn before he even start school, but if you ask a American how to count to 10 in Japanese would you say " At 30 you didn't know how to count to 10 in Japanese? Wtf." There are a lot of simple things you could learn but even if its simple, that doesn't mean you need to know it all. And knowing that it winter in Australia when its summer in America is something most people wouldn't know if they never left America. Its something you wouldn't even need to know.
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.
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?!?!?!
@@darugdawg2453 Unless you can test this yourself with peers (Not BS artists), then you can verify if it's accurate or not. Don't assume and take credits/demerits off somebody else's work. Didn't your teacher explain to you not to copy off another. And school textbooks are riddled with preposterous fallibles .
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.
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!
My 4th grade teacher exaggerated the earth's revolution as this video explained is wrong. A big misconception leading me to always ponder how the tilt could make a difference.
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!
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 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.
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.
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. :-)
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)
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.
+Edge Bob As stated in the video, the distance the Earth is from the sun does not affect seasons and always remember. the Earth is round and it's axis is on a tilt. Without these properties, the Earth would not has seasons. The sun rises and sets at different locations (North of east/west (summer), south of east/west (winter), and on the equinoxes due east/west). Also the sun is at a different altitude/height in the sky from day to day depending on the Earth's location around the sun. In the winter at solar noon, the sun is lower in the sky than at solar noon in the summer (about 48 degrees lower). Also the duration of sunlight we receive in the summer is greater by 6 hours (in New York, it varies with latitude) so that affects the temperature as well.
+Brien Schweizer Then why NASA considers Mercury as hotest and further the planets, colder? What stops Earth from not crashing in Sun when its coming closer to Sun? Can u replicate this model and prove the heliocentric model?
+SpirituallyAwakened Venus is actually the hottest planet in the solar system, not mercury. That's literally an example of how distance doesn't determine temperature
That proves Sun does not emit heat but friction of atmosphere is responsible for heat otherwise Mount Everset would be hotest place on Earth. And if Earth is a tilted ball with axis then it can't have same equator throughout the 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
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
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
You said it yourself mate. An Antarctic midnight Sun simply doesn't work on the flat-Earth model, at least not in the AE Map projection. Flat-Earthers aren't skeptics, they're denialists.
I think you meant rock science. Have they proven any of their claims. Tilt or no tilt, a sphere will still be a sphere and it will receive light rays the same way.
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
Please make a video like this explaining how Deadhorse Alaska has 24/7 sun in the arctic for over 60 days in the summer and 24/7 darkness for 60 days in the wintertime, while 630 miles south in Anchorage Alaska the sun always rises and sets. It would be handy to have that in the debate over a globe earth vs a flat earth.
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! :)
My observation is that the surface of water is flat and level. Contractors use a device called a "water level" that simply operates off that reality. If one simply observes the water around him it is plainly obvious that water always seeks its own level, will not cling to a curved surface in any way, and will not remain even and calm with the mass that supports is is spinning at over 1000 MPH. If 70% of the Earth is covered by water and the surface of water is level then I speculate that 70% of the Earths surface would be flat. I hope you will read my comments to this video and do recommend them to your flat Earth friend
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.
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.
- "but the sun which is many thousands of times larger than the earth is apparently 93 million Miles away which would shine light on the entire globe equally. that's a FACT" Uhm, no. You said it yourself: The Sun is, on average, 150,000,000 Kilometers away from the Earth.
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.
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!
I'm glad you asked. It was caused from the Theia collision in the Earth's infancy 4.5 billion years ago, which also resulted the formation of the Moon.
Sara Houck what a load of BS the earth has no tilt, and if it did off of what? where is the x and y graph in space to show it. What a load of crap. If the earth is a globe spinning in infinite space how do we know what is up and what is down? Is there a space map or compass and grid to show this? 4.5 billion years ago hahahah please don't tell me you believe that.
oh jeez I'm loosing brain cells. it has a tilt if you look at the solar system like you would be looking at a horizon the earth is tilted how would you explain the seasons then, honestly how stupid
That's a good point what is up down left right adjacent parallel perpendicular when suposdley were are in infanent space on a ball which what is there to actually do geometry we dont even know what our own oceans hold but we know how the universe started give me a break
Also been told what u believe u do nothing more then take the word of what you've been indoctrinated with you believe in only how the world has been presented to you not your fault just the people with all the God moneys fault
Omg are you serious??? Do you think airplanes jump across the ocean? It's called flying (duh). There would be no reason for buffalo wings if they could jump that far. lol You must think birds are some really great jumpers! Ha ha!! I really hope you were being sarcastic, cuz you sound very unedumucated. I bet you think the earth is round, too, and CNN is fake news. I'm glad I didn't go to your skool!!
Bro...i had this misconceptions that the distance of Earth from the Sun due to elliptical orbit caused seasons... But this video put some good knowledge into my brain cells.... Thanks ❤
omg i'm a 29 yrs old who just learned the reason why earth got seasons...... i didn't even know earth orbits around the sun... i just know that it spins on it owns...... omg i feel so stupid and i went to college!
Earth does not moves. School is not telling you the true. Stars with the Sun, Moon and planets as you called are rotating on an stationary earth. We are not rotating and there are experiments that are proving it. If you spin then the centrifugal force will push you out outwards. Gravity was a theory from Newton and he himself told us not to take it by heart. It was just a way to say that a Mass Falls with a velocity on seconds on meters square. Gases are not selected by Gravity? We are living inside a container. open your eyes. You do not have to be stupid as you said. There is a lot of information around about Flat Earth. please research it. Eric Dubai is very good explaining it to you . Find his web site. Good Luck
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.
Not at all impressed with the graphics, but after watching several videos about the earth's orbit, this one finally explained how the seasons worked. Thanks
