Earth as
a magnet
Have you ever used a
compass to find your way?
It works because the Earth
acts as if it has a giant
bar magnet in the middle.

where we all live. It is a


huge ball of hot, liquid


rock with a solid surface


called the crust. Planet


Earth travels in space.

The Earth’s surface


There are seven huge pieces


of land on the Earth’s surface.


They are called continents. They


cover about one-third of the


surface. Oceans cover the rest.


Spinning Earth


The Earth slowly spins around


once a day. The line it spins around


is called the Earth’s axis. At the ends


of the axis are the Earth’s poles.
