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 (a)   year cycle.

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

Answer explanation

The correct answers from the VIDEO are:

1 - Power grids can be shut off in advance

2 - Capacitors can be installed to help with the surge

3 - Special shielding on satellites and such
