Our planet's magnetic field is believed to be generated deep down in the Earth's core. The Coriolis force, resulting from the Earth's spin, also causes swirling whirlpools. This flow of liquid iron generates electric currents, which in turn produce magnetic fields.
Hope this helps!
It depends on their energy levels.
Yes. The law of conservation of energy says that energy cannot be created, nor destroyed, only transformed. An example of this change is a flashlight. It changes from electrical energy to light energy. :D
An acid is a substance that can dissolve some metals, break apart in water, and has a pH below 7. Acid taste bitter and can react with some bases to form salts. Acids turn litmus paper red.
Some acids, like Coca-Cola or Vinegar are harmless while some, like stomach acid, aren't so harmless.
