Dr. Art Poland, an astrophysicist, says both solar flares and coronal mass ejections are the result of magnetic activity on the sun. What is the basic difference between the two phenomena?
Solar flares have very high temperatures. They release energy in what high-frequency parts of the electromagnetic spectrum?
How quickly do the particles in a coronal mass ejection travel?
What soar phenomenon do you think produces shorter wavelengths?
It takes about two days for the cloud of material produced by a coronal mass ejection to reach and interact with Earth's magnetosphere. What phenomena are associated with this interaction?
