Learning How to Use A Compass
A Beginner's Guide
How It Works
How does a compass work? A compass works by detecting the Earth's magnetic field. The outer core, which is beneath the surface, is what produces these fields. The Earth's magnetic field has two main poles, a North pole and a South pole. These poles are slightly off, but they are close enough that they can give the general directions and be used for navigation.

What Is It?
An aurora is a natural light display in the sky, that is caused by the collision of Earth's charged particles and atoms in the high altitude atmosphere. It is called aurora borealis in the Northern Hemisphere, and aurora australis in the Southern Hemisphere.
