The presentation of the lesson is on point and give a clear understanding for both kids and the aged. It’s amazing and very resourceful keep it up sir.
Thank goodness RU-vid hasn't turned off comments for this nice video (well except for the robot voice.... pity!!) just because it contains the word "school". Honestly: RU-vid has become more insane by the day!!
M Firly Azzam:Troposfer adalah lapisan atmosfer terendah yang tebalnya kira-kira sampai dengan 10 kilometer di atas permukaan bumi. Dalam troposfer ini terdapat gas rumah kaca yang menyebabkan efek rumah kaca dan juga pemanasan global.
The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.
@@japnitkaurbawa2726 In English it is pronounced "how FAR away?", not "how MUCH away?". "Far" implies distance, where "much" implies an amount. So if you were to use "much" for distance you would say "how much distance between Earth's surface and the Ozone layer?", otherwise it would be "How far way is the Ozone layer from Earth's surface?"
I have a test (individual conference) at Tue Nov.17 2020. And this lesson that I didn’t understand from the teacher I understood it from you thank you and may God gives you wellness and guides you to the straight path.
Because the Earth's magnetic sphere extends quite far outside of Earth. Things like the ISS and other satellites are still within the Magnetic sphere (overlaps with exosphere). However, for further journeys such as to Mars or building a base on the moon then Solar radiation becomes a big issue.
@@s.w.a.kworld6302 Apparently, those that flew to the moon had higher rates of certain diseases compared to those who flew only within the magnetosphere. Small sample population, short timespans, and lack of research means exposure to solar wind is not well understood. www.nbcnews.com/health/heart-health/deep-space-radiation-caused-heart-problems-apollo-astronauts-n618116
Your question made me laugh. The rocket ships are not made of skin. The damn metal/steel/ structure protects the people inside the rocket. I would would guess that the engineering that went into the design and fabrication of the space suits took into account the radiation of the Sun. You meant to type in 1969 for Neil Armstrong.
This is such a amazing video, thank you sir for clear explaination although you teach in video, but still you come to comment space and replies the answers of all questions clearly. I like it . well I have subscribed it'to your's channel.well explained keep it up.
Check out Simon Clarks book 'Firmament: The Hidden Science of Weather, Climate Change, and the Air that Surrounds Us'. It's basically the only book on atmospheric science made for a broader audience, it is written really well. You won't be disappointed.
Where does the Earth’s spinning atmosphere stop, and the vacuum of space begin? At the Karman Line? Between the Exosphere and Thermosphere? Not all scientists agree that the exosphere is really a part of the atmosphere. Some scientists consider the thermosphere the uppermost part of Earth's atmosphere, and think that the exosphere is really just part of space. However, other scientists do consider the exosphere part of our planet's atmosphere. How is the atmosphere, which is a gas, and the Earth which is a solid, and the water, which is a liquid, all moving at the same speed as one body? And if the atmosphere is a gas, how is it different from other gases like wind from hurricanes or simple directional breezes? Inertia is the term that describes why we don’t sense the movement. But using the train or plane analogy, we must take into account the physical barrier, steel, aluminum, glass, etc...that prevents the resistance force to be felt. Roll down the window of your car and those forces will be felt. That leads to my question: at what point in the upper atmosphere does this invisible protective barrier exist? The exosphere or thermosphere or the Kármán line
The chemical composition of the stratosphere is generally similar to that of the troposphere with some exceptions, the most notable of which are ozone and water vapor. The air in this layer is very dry, as water vapor content is very low and it is about a thousand times thinner here than it is at sea level. However, it is rich in ozone because, it is the main region of ozone production.
@@AakashVerma-ib7nh The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases.
We have an atmospheric pressure gradient pressure decreases with the increasing altitude. There is no container between higher pressure and lower pressure throughout the atmosphere.
It’s fine explained nicely but why does it need to have 5 second pauses between sentences? It made it hard to watch and I needed to set it at 1.75 speed.
