To the layperson this is sometimes hard to visualize but the video below shows spectacularly the result of charged particles that are ejected by the sun, interacting with the geomagnetic field that shields the Earth.
"I am often asked how radio works. Well, you see, wire telegraphy is like a very long cat. You yank his tail in New York and he meows in Los Angeles. Do you understand this? Now, radio is exactly the same, except that there is no cat." : Albert Einstein

The Aurora
As amateur radio operators we are aware, more then most, of the constantly changing environment of charged particles above our heads. The way radio signals bounce off the ionosphere allows our relatively low power transmissions to skip across huge distances, sometimes completely around the world if the ionospheric conditions are right.
