Q. With reference to Coronal Mass Ejections (CMEs), consider the following statements:
1. During a CME, enormous bubbles of superheated gas called plasma are ejected from the sun.
2. They can occur anywhere on the Sun.
Which of the statements given above is/are incorrect?
- Statement 1 is correct: CME is an ejection of highly magnetised particles from the sun. During a CME, enormous bubbles of superheated gas – called plasma – are ejected from the sun. The underlying cause of CMEs is not well understood. However, astronomers agree, that the sun’s magnetic field plays a major role.
- Statement 2 is correct: Though CMEs can occur anywhere on the Sun, it is primarily those which originate from regions near the centre of the visible solar surface (called the photosphere) that are important for study, since they may propagate directly towards the Earth.
