Consider the following about Solar flares and coronal mass ejections (CMEs):

1) A CME can jostle Earth’s magnetic fields creating currents that drive particles down toward Earth's poles.

2) Both eruptions are created when the motion of the sun’s interior contorts its own magnetic fields.

3) While solar flares involve huge explosions of energy, CMEs involve formation of energy suctions in space that consume energy from its surroundings.

4) CMEs travel at the speed of light, Solar flares do not.
