The Pacific Ocean is the biggest ocean of them all; so big you can fly over it for 12 hours and still see no land. Imagine, that’s nearly as long as two days at school.

It is also the deepest ocean in the world- more than 10,000 metres deep, which is very, very deep; so deep that there is no light and it is so dark, even when it is bright and sunny on the land. Even I can't go that deep.
