The explorer Ferdinand Magellan named the ocean 'el mar Pacífico', which means 'the peaceful sea'.

Size: the Pacific Ocean covers around 30% of the Earth’s surface. It measures 165,250,000 square kilometres (63,800,000 sq miles).

Temperature: the temperature ranges from -1.4ºC to 30ºC. The water is warmer near the equator.

Depth: the average depth is about 12,467feet (3,800m). It is the deepest ocean of all.

The equator (an invisible line that runs through the centre of the Earth) divides the Pacific Ocean into:

  • The North Pacific Ocean
  • The South Pacific Ocean

The Pacific Ocean is full of islands, more than 25,000 of them. Most of them are found in the South Pacific.

The second-largest island in the world is located in the Pacific Ocean, it’s called the island of New Guinea.
