You know that the sea is salty. You can taste the salt. Some parts of the sea are saltier than other
parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot
sink! Fish cannot live in the Dead Sea. What a strange sea!
The sea can be very cold. Divers, who dive deep down in the sea know this. On the top the water
may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing
happens. When the diver goes deeper, the water presses up on him. So the diver has to wear clothes
made of metal. Some people who want to go very deep use a very strong diving ship!
