Particles thrown off the sun’s corona that can affect Earth’s magnetic field are called
A
a coronal mass ejection.
B
a coronal mass reflection
C
nuclear fusion.
D
sunspots.
Explanation: 

Detailed explanation-1: -Coronal mass ejections, or CMEs, are large clouds of solar plasma and embedded magnetic fields released into space after a solar eruption . CMEs expand as they sweep through space, often measuring millions of miles across, and can collide with planetary magnetic fields.

Detailed explanation-2: -Coronal mass ejections (CMEs) are huge bubbles of coronal plasma threaded by intense magnetic field lines that are ejected from the Sun over the course of several hours. CMEs often look like huge, twisted rope, which scientists call “flux rope."

Detailed explanation-3: -How do CMEs form? Coronal mass ejections form similarly to solar flares-a result of the twisting and realignment of the sun’s magnetic field, known as magnetic reconnection, according to NOAA.

Detailed explanation-4: -If a CME arrives at Earth, it can produce a geomagnetic storm, which, in turn, can cause anomalies and disruptions to the modern conveniences we have come to rely on.

Detailed explanation-5: -A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on March 12, 2023. The CME erupted from the side of the Sun opposite Earth.

Detailed explanation-6: -A CME can jostle Earth’s magnetic fields creating currents that drive particles down toward Earth’s poles. When these react with oxygen and nitrogen, they help create the aurora, also known as the Northern and Southern Lights.
