Ocean facts!
Bursting with wildlife and teeming with mysteries to be solved, our oceans are one of the most amazing habitats on Earth. Take a deep breath, gang, as we dive into our ocean facts…
Top ten ocean facts
1. Around 70% of the planet’s surface is covered by oceans. In fact, the oceans hold about 96.5% of all water on Earth.
2. The largest ocean on Earth is the Pacific Ocean, covering around 30% of the Earth’s surface.
Love marine life? You’d love our magazine!
Ask your parents to check out Nat Geo Kids magazine!

(AD)
3. The name “Pacific Ocean” comes form the Latin name Tepre Pacificum, “peaceful sea”.
4. The deepest known area of the Earth’s oceans is known as the Mariana Trench. Its deepest point measures 11km. That’s a long dive down!
5. The world’s oceans are home to incredible creatures that are masters of disguise! Take a look for yourself…
Did you know that we have a FREE downloadable ocean ecosystems primary resource? Great for teachers, homeschoolers and parents alike!
6. The longest mountain range in the world is found underwater. Stretching over 56,000km, the Mid-Oceanic Ridge is a mountain chain that runs along the centre of the ocean basins.
7. About 70% of the oxygen we breathe is produced by the oceans.
For World Oceans Day, we chatted to young Nat Geo Kids readers to find out what they think about our amazing oceans… What do YOU think?
8. The sea is home to the world’s largest living structure – the Great Barrier Reef. Measuring around 2,600km, it can even be seen from the Moon!
9. We have only explored about 5% of the world’s oceans. There’s a lot more to be discovered!
10. The sea can be described as the planet’s mega museum. There are more artefacts and remnants of history in the ocean than in all of the world’s museums combined! Pretty amazing, huh?
Did you know that we have a FREE downloadable Plastic Pollution primary resource, all about protecting our oceans and sea life? Great for teachers, homeschoolers and parents alike!
