It's amazing how he explains so correctly that Earth elliptical orbit apogee and perigee positions from sun have nothing to do with Summer/Winter seasons, but then at 2:55 he incorrectly attributes the Earth's inclination (tilt) affected distance from sun as the cause for our seasons. This is of course not the real explanation for the same basic reasons he gives in the first account, i.e., distance does NOT cause the seasons on Earth! The correct explanation FOR SEASONS is that the axial tilt of the Earth alters the amount of surface area (in each hemisphere) exposed to the sun. In other words, the amount of solar energy per area goes up (say at a specific Northern latitude) as the Earth's tilt is moved toward the sun -- this is b/c the amount of area in one location gets smaller as you tilt to the sun and that means increase in solar energy density (across the Northern hemisphere in this example). You can prove this to yourself with a basic geometrical proof demonstrating the solar rays (lines) striking a small surface area at differing tilts (angles).
@@diezelvh4133 No I disagree. You don't compromise the true science and play down the explanation to children. "Basics" does not mean misleading explanations. There is always a way to explain the physical principles to children in simplified way while still maintaining truth and accuracy of the physics.
@@TerracideDK Nope, both of those changes the temperature. It's just that the effect of distance is much less significant than the angle. The Earth gets about 6.6% more light per area when it's perihelion compared to the aphelion value.
@@TerracideDK So? Your first claim is still wrong, the distance does change the temperature however insignificant it may be. And 6 vs 40 isn't that insignificant either.
At 3:03, the suns rays travel millions of extra km during summer or winter not bec of the earth’s tilt. Otherwise a good presentation. Thank you for giving this presentation. I came here for the distance and angle info, really good explanations, thank you.
incorrect. The sun is closest (by only 1 million of 93 million miles during july) this has no effect on temperature. If it did, there would be no winter in Australia.
Great video, and great heat lamp comparison. I actually recreated an image in my mind of the heat lamps by having the heat lamps tilting at an angle and noticing that the foods would have varying amounts of heat.
Lucid analysis of sky radiation / azimuth angle / zenith angle, i.c. All fully illustrated by photographs! In my case it is great way to determine solar radiant heat gain. Radiance like a function, simply presented, is a function so this is valuable for me as a civil engineer with path of researching. Thank You so much for indirectly better define equation for radiance with radiant flux (we bring it in watts) propagating with a cone of solid angle from and through a specified point in time-line zone (all hemispherics) so I can imagine what is in real world like and making angle with the normal point to the surface. Also when referring to sky radiation it can be the zenith angle and azimuth angle to imply. All of this can bring me to Fresnel equations for reflection at the discontiniuty in refractive index. Thank you for effective presentation ! 🤌💥
All this can be made much, much easier. The easiest way is how an Optical Telescope basically works according to the 'Equatorial' principle. The equatorial mount has a north-south "polar axis" that is tilted to be parallel to earth's polar axis, allowing the telescope to swing in an east-west arc, with a second axis perpendicular to it so that the telescope can swing in a north-south arc. By swiveling the polar axis of the mount or mechanically moving in the opposite direction of the Earth's rotation, the telescope can accurately track the movement of the night sky.

Say hello to your science Teacher for me and please give your teacher this message for me. " large amount of Water is flat and level" and can't be curved around a sphere. Greetings Stationary Flat plane
All my life my teachers, my parents, friends... Taught me that the Sun was at 90° at 12 am regardless of the season or the location, it makes me realize that at school they teach us things wrong, for example they teach us to find the altitude of a tree from the length of the shadow knowing the angle of the sun, they tell us which is a practical exercise, but in real life, if we were never taught how to find the angle of elevation of the sun, how can it be called a practical exercise?
Sorry to tell you, Your teacher, Parents and friends never told you the truth. We are living on a magnificent beautiful stationary Flat plane. I salud you to the reality as it is. I know the truth is hard to swallow. Deep inside you, you know that water is flat and level. can't be curved around a sphere. Greetings Stationary Flat Plane.
It's especially crazy how the sun changes directions so that it can also do an elliptical on the other side of the world. Insert sarcasm. Think about this elliptical. How can it be? Why doesn't it create opposite ellipses over the opposite hemisphere, like an elliptical orbit should do?
Yeah. He also got it wrong about the tilt and the sun's rays. It's not that the sun is closer to the earth in the (northern hemisphere) summer, the tilt doesn't make much difference in distance. What's important is that the sun's rays are comin' straight at us. When the rays come in at an angle in our winter, then we're colder. I'll bet he knows that and just became mixed up while making this, a "typo", so to speak, but its really, really important.
There is one notion that is wrong I think. The tilt changes the photoperiod (duration of the day)and angle so the ground absorbs that energy. The distance is negligible…
Well, first of all, you need to get the facts straight about the phenomenon - it's not everyone, though it is about 99% of the world's population, and it's not that they "can see the Sun", but that they have some amount of sunlight. That sunlight includes twilight, when the sun is below the horizon but you still receive light from it due to refraction and atmospheric scattering. Twilight is defined as when the sun is up to than 18° below the horizon, and the portion of the Earth that includes daytime and twilight works out to about 70%, so way more than half of the Earth "receives sunlight." . A few things to consider: the Pacific Ocean covers about 30% of the Earth's surface, the Earth's land surface is concentrated in the Northern Hemisphere and the population of the Earth is not evenly distributed across all land. It shouldn't be too hard to understand that in the summer, with more daylight in the Northern Hemisphere than the Southern, when it is nighttime over the Pacific Ocean, most of the Earth's land will receive some daylight, and as it turns out on July 8th, most of the World's population is concentrated in the land that is receiving some daylight.
@@TremayneDouglas "How come everyone on Earth can see the Sun at the same time on July 8?" That's because people are not equally distributed over the surface of planet Earth, but some areas are populated, while majority of areas are not populated at all. And, during that days, 99% of inhabited are is covered with sunlight. "I'm sorry bro but you'll wake up one day." How do you "explain" that on your fantasy pizza land?!! ROTFL
