Solar Activity and Magnetic Fields

In ​ (a)   a large solar storm caused ​large drapes of light to extend as far south as the ​ (b)   . It would come to be known as the ​ (c)   Event.

• 1989
• Carolinas
• 1859
• Carrington
• Rodney
• Caribbean

What generates magnetic fields?

• The presence of a compass

• Anything moving in a circular pattern

• The movement of electrically charged particles

• The interaction of two or more planetary bodies

Areas of intense magnetic activity on the surface of the Sun are called ___.

• sundogs

• coronal mass ejections

• solar flares

• sunspots

When these areas of intense magnetic activity become ​ (a)   and strained, they snap off and release ​ (b)   in the form of ​ (c)   .

• twisted
• energy
• Coronal Mass Ejections
• very small
• Solar Prominences

How long does it take for a typical coronal mass ejection to reach Earth?

• a few minutes

• a few days

• a few months

• a few years

When the CME reaches Earth it interacts with the magnetic field to create light shows we call the ​ (a)   .

• auroras
• halos
• sundogs
• rainbows

When these storms reach Earth they are generally harmless to ​ (a)   , the high-energy particles falling into the atmosphere create secondary ​ (b)   , which in turn generate rogue currents that short-circuit ​ (c)   .

• humans
• magnetic fields
• electrical equipment
• car engines

Researchers have learned the Sun’s usual magnetic activity follows an __ year cycle.

What are three (3) mitigation measures (safeguards) we can do to help lessen the effect of solar storms?
