Why We Have Seasons
Ғылым және технология
How did Earth get its season? Neil deGrasse Tyson and comedian Chuck Nice explain how the Earth got its seasons, its axial tilt, the Milankovitch Cycle, and more! What are seasons like on other planets?
Neil breaks down the biggest misconception about Earth’s elliptical orbit. Why is noon not the hottest time of day? Why is June not the hottest month of the year? We explore the Hadean Period and how the Earth got its tilt, the Milankovitch Cycle, and what causes ice ages. Plus, discover what seasons on Venus and Uranus are like.

No they are actually quite embarrassing. Such a pity because Neil has an amazing wealth of knowledge to share.
When Neil wants to, his voice is just so relaxing and smooth. Man could probably read the dictionary to you and still be relaxing.

It's not a time delay thing. It's the fact that the sun doesn't just stop heating at midday/mid-season, it keeps heating as the day/season continues, albeit at a reducing rate. It's accumulation not delay.

Cyclones happen the most during October in the Eastern part of India because the Indian Ocean heats up maximum in October!! But now a days Cyclones happen even during earlier seasons because of global warming temp rise!
When one talks about the planetary tilts, how is horizontal and vertical determined in space? What is the reference point or what are they measuring it against to determine horizontal and vertical? Not sure if I am asking this question correctly but perhaps someone will understand what I am getting at lol.
@mriandecker6533
Ай бұрын
So, when we describe the tilt of a planet, it's with respect to that planets orbit around the sun. So, take the Earth. Assuming that its orbit is 0 degrees, Earth tilts 23.5 degrees off its orbital plane. For describing a tilted orbit, it's with respect to the sun itself. Assuming that the sun's tilt is at 0 degrees, any planets orbit is measured from that. That being said, there is no universal reference point. Everything has to be measured with respect to something else, in this case, the sun is that reference point. Hope this helps you to understand!

@@mriandecker6533 A tilted orbit such as Pluto's is usually specified in relation to either the Earth's ecliptic (orbital plane) or the invariable plane which is the average orbital plane of the entire solar system. The Sun's equator does not match either of those. Neil said Pluto's orbit is tilted 17 degrees, that is relative to the ecliptic. Look up 'invariable plane' in wikipedia if you want more information including the sun's tilt in relation to both the ecliptic and invariable plane.

Absolutely LOVE Neil's videos. And this tandem is a 2 in 1, funny and educational. Never get tired of them!! Please never stop posting!!

Kudos for the animated graphic of the earth displaying the correct direction of the tilt! I see so many images, memes and analogies all over the Internet that get that wrong!

Here in South Africa, the hottest time of the day in Summer is roughly at 15H00. In Winter, the ground heat shifts slightly back by about one to two hours, so 13H00-14H00, when it gets quite warm. Obviously, this is because the days are shorter, hence this shift in temperature and ground heat. 😂🤣😊
Awesome. One of the episodes that I bookmark for my kids.
Great video Neal, but I wish the tree in the graphic had some individual leaf motion
My Geography teacher didn't explain this so eloquently and more understnadably than Neil has. Cheers to Neil.
Finally understand what tropic of capricon is. I pass this landmark everytime🤔😮
Neil and Chuck, y'all rock! Peace
Such Grace! Many Nice!! ❤ I could not stop smiling, great job!
Neil for President 💙
Great talk on the seasons! I grew up near the southern shore of Lake Ontario in western New York. The effect the lake's surface temperature has on surface temperatures on land (if you're close enough to the lake) is quite substantial in the spring and very early summer. And the opposite occurs in the fall and early winter. 🙂
12:16 I literally laughed so hard right now it made my chair unlock the recline. This was so good guys.
Loving this new format!
Neil, I absolutely love everything you do. I’ve read several of your books and love the way you explain stuff so idiots like me can understand.
This was great, as always. I love Star Talk. Neil, you and Chuck are the best.
Love the new setup, gentlemen!
This was a fantastic episode. Even though I knew some of these things, it's still fun to check your knowledge on. Keep fighting that fight for Pluto Chuck!! haha
This new setup is amazing 👏🏾
So much Fun! Mr Tyson makes science and learning fun and easier…much appreciated
What a fantastic episode
Love this channel, really love it.
I would love a video on what Tyson thinks about the orbit of the planets and the orbit of electrons on an atom being displayed so similar. Thanks Sirs! Love this channel.

Gravity bends light, gravity bends space, gravity bends matter, even bending them to the point of creating a supermassive black hole. Gravity can actually slow down time itself near a massive object. I wonder if time itself actually being 'bent' by gravity is what we perceive as time slowing down?
Love it!
