Seasons: What causes summer and winter?

A simple introduction for students that shows how the tilt of the Earth's axis of rotation is responsible for our seasons. This video makes up part of the Shedding Light on the Sun and Earth series, which covers all the basics of climate science: seasons, winds, weather, hurricanes, and how land masses and oceans affect local and global climate patterns. Each video comes with an activity sheet. The activity sheets include map reading, weather charts, graphing and more.
The full series is available on ClickView, Learn360, Classroom Video on Demand, and Safari Montage.

Thank you. I'm an older adult and needed a refresher and just found this. Perfect explanation! I appreciate you!

Man I had some really big misconceptions about how seasons happenes. Thanks a lot guys.

In my mind i was always that spring is green, autumn is red, summer is yellow and winter is white or blue. This is due to the causes that make these color appear in just seasons.

This is perfect for explaining the seasons. Thank you! Loved the gymnasium setup.

Like the way you gave the Sun’s view of the Earth, that really helped in the visualization

Beautiful SubhanAllah...glory to the creator and maintainer of our home (temporary)

This video is amazing!! Just the answer I was looking for! Thank you for all the images, now i can really imagine why Australia has winter while America is in summer. I'm 31, American, and never learned this in school.

Finally the out of the ordinary explanation I was looking for!!! How Great is God that created the perfect inclination for our planet and keeps the perfect order in the universe.

thank you. it's a much more clear and simple explanation than any i've encountered.

[kevinhenry]

Thank you. This is the first time it has been explained how the angle of tilt increases the area of land receiving the radiation. And the amount of time that the land is receiving that radiation. I now understand

[jumbogadgets]

This is the best explanation I ve ever seen

[sproglode]

This is the best video describing the seasonal variations - thanks so much - David

[elizabethschraderking]

This is great! I especially like your demo in the gymnasium and the way you've positioned the camera to represent the vantage point of the sun. Then, your description of how the same beam of light striking north vs. south of the equator during a solstice results in two different intensities is quite elegant.

[LooseTubes]

What an excellent video, short and clear. Thanks!

[f-ranci]

I have to admit, I forgot how it works. This is great explanation.

[talie]

I never knew this.
I would t doubt if this was taught and it just didn’t register for me.
Your explanation was very thorough for me.
Thank-you, Sir.
Great presentation. 👏

[guitarsncarsnart]

So it's the AREA covered by the same amount of sunlight. It's not the Distance (sop much anyhow). Great explanation. 3:22 explains it really well for me.

[MrRandallDish]

I was needing a refresher and this was perfect and more. Thank you.

[sanjibsarmah]

Very effective way to understand whole

Excellent vedio.👌. I wish to see more in the public interest, the video showing that all together movements & effects of earth & moon with sun. With understanding of daylight /moonlight, night/night moon, sun/moon effilepcy, seasons etc
