CME stands for what?

• A. Current Mass Emission
• B. Coronal Mass Ejection
• C. Coronal Magnetic Emission
• D. Cosmic Magnetic Event

Answer: (B)

CME stands for Coronal Mass Ejection, which is a sudden, huge release of plasma and magnetic field from the Sun’s outer atmosphere, the corona, into space. The word Coronal points to the solar atmosphere involved, Mass highlights the enormous amount of solar material expelled, and Ejection captures the rapid outward blast into interplanetary space. This is the standard term used in solar physics, describing a real physical event different from everyday terms like an electrical current or a generic cosmic event. The other phrases don’t fit the established terminology: they either confuse the nature of the material and its source, or use terms not used to describe these solar eruptions.
