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.

@tylermitchell9131 9 ай бұрын

I enjoyed the video! I have one question though. You mentioned the sun hitting the one hemisphere more directly, causing summer in that hemisphere, and in the other hemisphere the sunlight is more spread out, thus less energy, thus cooler. I had never heard or picked up on that before. I always assumed that it was because the one hemisphere was a little bit closer to the heat of the sun for that part of the year, and the other a little bit farther away. Does this also affect the temperature? Thanks! I love orbital demonstrations.

@LiacosEM 9 ай бұрын

Thanks Tyler. The earth has a diameter of about 13,000 km but it is about 150,000,000 km from the sun. The difference in distance from the sun for the two hemispheres at any given moment is basically zero. Also, the orbit of the Earth is not circular but slightly elliptical. As it orbits the sun, the closest that it gets is 147 million km and the furthest it gets is about 152 million km. And yet, both hemispheres experience summer and winter on cue!!

@@marcyc1695I am in Australia but in 2017 i have traveled to NYC, yes in Australia is winter in July and summer in NYC. I also believe the seasons start on the equinoxes and Solstices. Now because the earth is furthest away from the sun in early July that is why in NYC has a longer spring and summer.

I couldnt comprehend if on the other side of the world (Im in the North of America, NewYork) for example if it would be the hot part of the year while it as cold on my side. I see now that it is flipped. Its confusing stuff. Especially because I didnt realize it depends on North and south hemispheres.

The Earth is at the angle of 23.4° to the orbital plane. I find it interesting, though it's probably not significant, that that is close to half of 45°. Which is half of 90°. Which is half of 180°. Which is half of 360°. Which is a full circle.

According to Kepler's theory - the distance of the earth to the sun is not the same during winter and summer. Why are you in a perfect circle? How could the sun be farther away during aphelion and be summer time? And be closer to the sun during perihelion -and be winter? Not to mention the sun's size remain the same in the sky? Heliocentrism doesn't make any sense, at all. Our globe is stationary. The sun moves!
