Multiple choice

What is a coronal mass ejection (CME)?

  1. A large eruption of plasma from the Sun's corona

  2. A stream of charged particles emitted from the Sun's surface

  3. A region of the Sun's atmosphere with a strong magnetic field

  4. A dark spot on the Sun's surface
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coronal mass ejections (CMEs) are large eruptions of plasma from the Sun's corona. They are caused by the sudden release of magnetic energy stored in the corona, and can travel through the solar system at speeds of up to 2,000 kilometers per second.
