the molten iron core
Because the Earth is like a giant magnet it keeps the Sun's radiation from killing us.

Stone and Metals
You can't make a magnet with only one pole. Every magnet, whether natural or electro- , has two opposite poles. One pole is attracted to Earth's north magnetic pole and repelled by Earth's south magnetic pole. The other one is attracted to Earth's south magnetic pole and repelled by Earth's north magnetic pole. For the same reason, there's no such thing as "repel Earth's magnetic field" because Earth itself is a giant magnet, and also has two poles. One of them attracts one end of any magnet, and the other one repels one end of any magnet. Make any electromagnet you like, and figure out a way to hang it up and let it turn freely. It'll line up with its ends pointing to the Earth's north and south magnetic poles.
Its Earth's twin and it has a 800 surface
The same way you make it on earth. Use either some form of rotating magnet generator or a solar cell.
Giant Tortoises
Scientists study the characteristics that make life on earth possible so they can figure out when life will know longer be possible. They also want to know what causes life to not be possible.
It lines up in the same direction :)
go read the book lol
"plates" are the term for the giant sheets of rock on the earths crust
by stroking a magnet the right way you will make the magnet very happy, this will cause it to magnetise better, much like stroking a cat or dog. a happy magnet is a strong magnet
