Earth’s distance from the Sun is just right, not too hot or too cold. Earth is the only planet with the right atmosphere and enough water to support life.

Earth is known as the blue planet because it appears blue from space. This is because 70 percent of the Earth’s surface is water!

Earth is like a giant magnet, with poles at the top and bottom of the planet. Earth’s molten iron core creates a magnetic field. A compass uses a small magnetic needle that always points toward Earth’s top, or North, pole. Using Earth’s magnetic field, the compass tells us whether we are facing North, South, East, or West.
