The sea

The sea is a dark place. The sea can be beautiful but it can also be dangerous. It can be shallow but it can also be deep. The deepest part is more than 11,000 metres deep!

When the weather is bad, the waves get bigger and bigger. Sailors are afraid of bad weather. Sometimes ships sink and go to the bottom of the sea. Sometimes ships disappear when the weather is good and no one sees them again.

The Bermuda Triangle, near North America, is one of the most dangerous places in the world. More than 50 ships and 20 aeroplanes have disappeared there. No one knows why.
