This was very well explained! Last week I was debating with a friend of mine that claimed that sun rays always hit perpendicularly in the Equator line. I argued that due to the tilt of Earth's axis with respect to the orbit around the sun, that didn't make sense. He quickly googled something to prove himself right, and read it to me while I was driving. So, I accepted it. But, it never quite made sense. Today, I decided to look for seasons' explanations, and came across this video. As it turns out, this video proved my argument. My conclusion from your video: The “parallel” where the sun rays hit perpendicularly moves periodically like a pendulum between -23.5 deg to +23.5 deg of latitude (a.k.a. between the tropics), with the middle point of the pendulum's trajectory being the 0 deg latitude -- a.k.a. the Equator line (“parallel”). This "pendulum" would have a period of T = 1 year.

Wouldn’t Pb still decay at the same rate, no matter the amount of weathering? That’s kind of the point of using a certain mineral as diagnostic testing, isn’t it? That they can reliably decay at a certain rate!?! Or do they use something else like chromite for weathering?

Can someone help me how to saved this video in my phone?please

I don’t think this is very clear at all. The video does refer at one point to “the sun hitting the Earth at 90deg” and later “the North Pole is further away”. I don’t think it is ever clarified fully that it is not the distance from the Sun, but the angle of presentation that creates the seasons. The OU used to explain this by using a slide projector (I know, you have to be old enough - think of a data projector), where if you angled this from the side some of the image would go beyond the screen on to the wall. This loss of image on the screen directly relates to how much sunlight, and subsequently heat, is reduced.

Thank you so much for the information. It helps all of us understand global warming areas and times of the year.

Earth Rocks gets an "A" for first rate teaching. The best mode of learning measurement at the K-12 level used to be shop classes. The disaster of the Gates Common Core Curriculum over the last 20 years has destroyed shop classes and other hands-on learning such as Home Economics. I witnessed years of students who did not master things as basic as a twelve-inch ruler. They had no concrete grasp of measurement because the curriculum became based on increasing levels of abstraction. This lack of basics has had dire consequences when these students show up in higher education.

Minerals aren't like pens. Sand would be better for illustration. Awesome video. As Shawn Willsey calls them a general term, sexy rocks 😂

Close to perfection to understanding 🙏

8 years ago in South Africa there was a boy getting ready to write his final examination in matric on Geography, he wasn't good at science and his marks where hanging on to dear life, and it all came down to geography. So he studied and studied and he came across this very same video, but he ignored it because what are the odds of this being asked in the paper, Question 5.2.1 what season is in the Southern hemisphere during September😂😂, long story short i passed my exams and guess what job i chose, a geography teacher. So every now and then when its time to teach about this very same topic, i just open youtube look for this very same video and let you work your magic. Works everytime

Why is a Tsunami on the open ocean a shallow-water wave?

Xd

My favorite seasons are all of them i like all seasons in fact

Why don't we use concept like east pole and west pole

Can you give me reference paper on this topic, it’s really amazing to know about this topic! Keep it up, nice content.

excellent informational video

This video is good.

Thank you for the beautiful video and overall for the information!!!

another high quality earth rocks! video

Excellent tutorial. Thank you. Just what I was looking for.

No one can ever convince me there is no God.

Pov:U often watch on youtube and that's why you got the top of ur school

It actually takes 365.256 days for the earth to orbit the Sun. 2024 being a leap year.

That was FUN , Love the thinking music too :)

Why on earth (lol) was I taught in school that the earth literally tilted like a plane wing for the seasons?

Thank you for your concise explanation that was remarkably easy to understand. Well done.

Excellent synopsis.

Me, an introvert, traveling to the north in january and south in july so i can remain in darkness and solitude.

Thank you

After 9 years,still perfect!

good lecture

amazing stuff!

Thanks!

Thank you for the information. It was so helpful. ❤️ I could understand it so much better in just 5 mins because of this video

If the earth had zero tilt, what would the moon location be in the earth sky

so is earth tilted to left (as in video 0.25 to 0.30 shows) or tilted right(as in most of the video shows)?. I think Left side! because Vancouver vs Halifax, NS. Means west is more tilted downwards as if earth is tilted/bent to the left and because of that Vancouver has more semi tropical plants/jungles than East end Halifax! if we tilt the globe to left then it shows how Vancouver faces more sun than Halifax! One more point In 2024 and still, why we do not have live camera view of earth from space? to see tilt, seasons, etc.

Although this presenter implies it, it can be properly inferred that the current Sierra Nevada is its 2nd generation. Those stranded bodies of older metamorphic rocks atop later granitics are commonly mentioned as "roof pendants". While subduction conveyance provided magmatic feed for most recent uplift, the huge graben of the Owens Valley along the eastern flank of the Sierra Nevada portrays the crustal extension that aligned Mono-Inyo Craters and Mono Lake with the Long Valley Caldera. Also, while not mentioned, California's Transverse Ranges (10-11,000-ft.), which are physiographically the northern border of the Greater Los Angeles Basin, are strong indications of a distinct inland tectonic vector, approximately pushing Los Angeles toward Las Vegas. Also, the Cascadia Subduction Zone, which is offshore from NorCal, Oregon, & Washington, hosted a 9.0 quake in 1700 (tsunami registered in Japan), before Europeans began to venture into that region.

Born to have fun, forced to take a geology class. Your information is good, no knocks.

Pause Now ❤

What is equinox

Hey mam can I contact you like do you have any social accounts

What kind of ice cream is served at a hydrologists awards dinner ? A Cone of depression. …

This is my class! :)

Thank you .

Thank lots for sharing 👍 💚 ❤️ 💙

Huh, I understand that season's are explained by the tilt of the earth. However, if the sun isn't at the centre of the ellipse, surely the winter in the Northern hemisphere is warmer than winter in the southern hemisphere. I guess light only travels in straight lines so the sun won't rly be hitting areas that don't face it. But I still feel like proximity to a giant ball of fire and gas must affect temperature to some degree?

Amazing

Very good video

Hi

I wonder why they didn't mention the names of these distances. Like when the earth is closest to the sun is called Perihelion and when the earth is farthest from the sun is Aphelion. Is like only two helios or sun seasons in a year. Either close or far.
