Ionosféra
The ionosphere is a region of Earth's upper atmosphere, approximately 60 to 1,000 kilometers (37 to 621 miles) above sea level. It is characterized by the presence of ionized gases, meaning atoms and molecules that have lost or gained electrons. This ionization is primarily caused by ultraviolet (UV) radiation and X-rays from the Sun.
The ionosphere plays a crucial role in radio communication. It reflects radio waves, allowing them to travel
The structure and density of the ionosphere are not static. They vary significantly with time of day,
