What is the reason for this? Is it because of the Earth's rotation?
If the Earth did not rotate would that change the "half" to another value?Rod Alexei said:What is the reason for this? Is it because of the Earth's rotation?
Hi Rod, please post your source for this so that everyone can read it. Thank you.Rod Alexei said:What is the reason for this? Is it because of the Earth's rotation?

Which is why I asked for the source, it often solves the problem.davenn said:he just has a misunderstanding of the real reason ... which is what 256bits and myself are trying to coax out of him

Exactly, that might be his first clue that his thinking is wrong. I guess I could word it "Have you actually read this anywhere?" But we ask for sources, because many times, people actually come up with some oddball website that they were reading and we need to explain why it's wrong. Or they read a valid website or book, but they misunderstood what they read. I find it best not to assume that they didn't read, see, or hear something that triggered the thought.davenn said:I don't think there is a "source" as such
Generally, discussion topics should be traceable to standard textbooks or to peer-reviewed scientific literature

davenn said:@Rod Alexei ... have another try ... think about it from an Earth visibility point of view ...
do you now see the reason ?

The ionosphere is the layer of the Earth's atmosphere that is ionized by solar radiation. However, the amount of ionization depends on various factors such as the strength and angle of the Sun's rays, the Earth's magnetic field, and the composition of the atmosphere. As a result, only half of the Earth's ionosphere is being ionized at any given time.
The Earth's magnetic field plays a crucial role in protecting the ionosphere from solar radiation. When the Sun's particles interact with the Earth's magnetic field, they are deflected and cannot reach the ionosphere. This results in only half of the ionosphere being ionized by the Sun.
No, the amount of ionization in the ionosphere varies depending on the time of day, season, and solar activity. During the day, when the Sun is directly overhead, more of the ionosphere is being ionized. At night, when the Sun's rays are not reaching that part of the Earth, the ionosphere experiences less ionization. Additionally, during periods of high solar activity, more of the ionosphere is being ionized compared to periods of low solar activity.
The ionosphere is important for radio communications, GPS systems, and other technologies that rely on radio waves. When only half of the ionosphere is being ionized, it can affect the transmission and reception of these signals. It can also impact the Earth's climate and weather patterns, as the ionosphere plays a role in the distribution of energy from the Sun.
Yes, human activities such as nuclear explosions and high-frequency radio transmissions can temporarily disrupt the ionization of the ionosphere. However, these disruptions are typically short-lived and do not significantly impact the overall ionization of the ionosphere by the Sun.
