It's a hot time for some cool science. And I'm telling you, you won't find a better visual for how seasons occur. This'll clear it up.

  • Learned more from this video in 2 minutes then I did in my 4 hour college class. Why can't all teachers teach like they're teaching children?!

  • @mindyourbizok - The tilt does not cause day and night. Day and night is caused from the earth spinning. One spin around equals one day.

    Watch the video from about :55 seconds and you'll see the earth spinning. Yes, the northern hemisphere is farther away but it's still getting hit by the sun.

  • I'm confused. The earth's tilt causes seasons and day and night. How does all this tie in. When the southern hemisphere is closest to the sun, how do you explain the northern side getting day light?

  • Nasa, Richard Gross

    The quake also shifted the position of the Earth's "figure" axis (which is different from the planet's north-south axis). This shift in Earth's figure axis will cause Earth to wobble a bit differently as it rotates, but it won't cause a shift of the Earth's axis in space -- only external forces such as the gravitational attraction of the sun, moon and planets could do that.

  • IT'S SUMMERRR TIME.

  • It's summer time and put on your winter coat

  • I´m so glad I found this video! We´re learning about this at school. But I coundn´t understand anything about what we learned there....

  • around 1:19 ***

    

  • "put on your winter coat" HAHA around 1:21

  • Doesn't the axial tilt coincide with the magnetic north? I always thought that was why the earth tilted because the magnetic pole moves around.

  • nice video... helped me to tech my nephew in just 2 mins...
