A closer look at the movement and position of the Earth in relation to the sun causing us to experience the four seasons - summer, autumn (fall), winter and spring.

The Seasons
The Earth is divided into two halves - the northern hemisphere and the southern hemisphere. As the Earth revolves around the sun, sunlight hits one hemisphere more directly than the other. This causes us to experience seasons. In June, for example, the northern hemisphere is tilted toward the sun and is in summer. The southern hemisphere is tilted away from the sun and is in winter.
Summer is the hottest season, occurring between spring and fall. Summer is the seasons with the most hours of daylight. It has the earliest sunrises and the latest sunsets.
Fall is the season after summer. During fall, the temperature gets cool and the number of daylight hours begins to decrease. The leaves on some trees begin to change color and fall away. This will help them to save energy during the approaching winter.
During winter, the Earth is tilted away from the sun. The weather is the coldest season and days are the shortest. The sun rises later in the morning and sets in the late afternoon. In some parts of the Earth, winter is also the season when it is most likely to snow. The ground may be covered in ice and lakes and streams may freeze. Some animals become inactive or migrate to warmer places during winter.
As winter moves to Spring, the number of daylight hours increases and the temperature gets warmer. Spring is the season for reproduction. Trees regrow there leaves and start to produce flowers. Animals become active and also reproduce during spring.
Great work!!! In autumn and spring, I do not see how the Northern and Southern hemisphere are at equal distances from the sun. Feel free to shed more light
During the equinoxes, which occur in spring and autumn, the tilt of the Earth's axis is such that it's perpendicular to the sun's rays. This means that the sun is positioned directly over the equator, making the amount of daylight and darkness nearly equal for both the Northern and Southern Hemispheres. It's not about the hemispheres being at an equal distance from the sun, but about them receiving roughly equal amounts of sunlight.
So, even though the distance from the sun to the Earth changes throughout the year due to the elliptical shape of Earth's orbit, the distance isn't the main factor causing the seasons or the differences in sunlight between the equinoxes and the solstices. It's primarily about the angle at which sunlight hits the Earth.
In Chicago we have something called seasonal depression I can't imagine how bad it gets in the northern hemisphere as it's dark for so long 12 hours is about all I want or need 3 months jeeez.
Seasonal depression is actually caused by the holidays and the pressure caused by it. January is the worst month because the credit card bill comes
@@edwardtobiasen3386 it isn't caused by the holidays it's exacerbated by the holidays been in the city for 52 years holidays is just a contributing factor.
Chicago is in the northern hemisphere. You mean further north in the northern hemisphere?
@@edwardtobiasen3386 😂😂😂 What lmao. No it’s not
If seasonal depression is due to the darkness, then why is it the same in the southern hemisphere
Super excellent explanation sister ❤❤❤❤
I watch many videos but I can't got the main point
Really awesome 🎉🎉🎉
Great video to learn about seasons. The scences are very beautiful. Thank you
Glad you enjoyed it
@@NGSciencegvvvvv
Excellent ❤🎉
This video is very helpful for me at all!!!😃😃😃
You helped me out! Thanks a million!
thank for helping me learn
Very educative. I'll get to US inshallah
😮wow how informative, can you also make a video of how is it possible to stay in sun view from Cali to Moscow on a flight. Thank you in advance
Yes I can...
On a flight from California to Moscow, it's possible to stay in the sunlight the entire time due to the way the Earth rotates and the path the plane takes. Let's break it down:
Earth's Rotation: The Earth rotates from west to east. That means if you are flying from the west (like California) to the east (like Moscow), you are going in the same direction the Earth is rotating.
Flight Path: The flight path, especially for long flights, is not a straight horizontal line on the map. Planes often take a curved path, which can be more north or south depending on the specific route. This is because the Earth is a sphere, and this path is the shortest distance between two points on a globe.
Sun's Movement: The sun appears to move from east to west because of the Earth's rotation. So, when you are flying eastward, you are kind of "chasing" the sun.
Here's a simple way to imagine it: if you were to stand still and watch a sunset, the sun would eventually go down and it would get dark. But if you started moving quickly to the east, you could keep up with the sun, and it would stay above the horizon.
So, on a flight from California to Moscow, if the timing and path are right, you can potentially stay in sunlight the whole time because you’re moving eastward fast enough to keep up with the sun. Isn’t that cool? It's like a never-ending sunset! 🌞✈️
great video! thanks!
Earth Science Novato is a better explanation for cause of seasonal weather and seasonal shadows.
❤❤❤❤
I love space and especially earth so
Thanks you so much

Excellent 👌🏻
Thx maam now i know😁
This is missing a very important concept that should be in a diagram- the difference in the angle of the sunlight hitting the earth. In summer, the angle of the sun's rays is more towards 90 degrees, and in winter, it is more towards Zero degrees. The more direct the rays, that is, towards 90 degrees, the more heating of the earth takes place. Directional rays from the sun to the earth illustrate this. It should be depicted here. Mistake.
The degree is relative with the latitude. The sun always hit with 90 degree, just different part of earth
I think it is because of the age range they are targeting. What you are talking about would be better for a 4th or 5th grade level. This is probably a 1st or 2nd grade level who are just learning about axis, orbit, hemisphere, revolve and rotation. Just my opinion
Thanks for teaching me
It's our pleasure!
Very good and interesting 👍
Thank you! Cheers!
So Beautiful
Very nice bro 👍
Bro remember me?
Who created this amazing system?
No doubt that it is God.
cool
cool
I still don't understand this
Wow
first point what you said about some area not experiencing night hours is false, Not experiencing virtually any day hours is true howeever, the other point is that the video misses some really important key information relevant to temperature at a given time of year, That is that areas further away from the relative position of the equator, experience a larger area of land covered by the same amount of sunlight (heat) this greater dispersion of light means that average heat in any area covered by the same amount of light is reduced, and therefore the temperature is also reduced, closer to the equator the reverse happens
You can actually do a simple experiment to validate this, get a globe or a football etc and a torch, err flashlight if you are American. when the torch shines on the object the perpendicular facing side of the object will have a beam of light in a much more narrow band than if you shine it further away from this relative centre, where the same amount of light and therefore heat disperses over a larger area, therefore in effect lowering air temperatures within that region.....Anyway some very pretty visuals in the video.
my school is explained this chapter so I see this vedio

What a patronising voiceover
I dub it #Bitchsplaining
I like the information, but the reading is terrible. I get maybe it's for younger kids, but really, I'm not sure if I want to show this to my 13 year old students because it sounds like she is talking to kindergarteners.
I’d rather have a female voiceover than a male voiceover, it’s more aesthetically pleasing
