The Earth has a naturally occurring magnetic field because of the ocean.

• True

• False

• Ocean water has salt which is conductive

• Actually, it can only be formed in the clouds

One of Earth’s Magnetic Field purpose is...

• To protect us from aliens

• To give Earth energy

• To make lighting storms

Auroras occur because

• Spirits are leaving the Earth

• Space is projecting city lights in the atmosphere

• The ions in the solar winds are interacting with the magnetic field

• The ions are speeding down the atmosphere

• The gravitational pull of the magnetic field lights up the sky.

Compasses work because...

• Dark Arts Magic

• The needle is magnetically attracted to the Earth’s pole

• Natural AI

• It is magnetic itself and repels against the magnetic poles
