While there's only one global ocean, we divide it into different parts for easier understanding. These parts are called oceans. There are 5 oceans.

The Five Oceans
Historically, we recognized four oceans:
Atlantic Ocean
Pacific Ocean
Indian Ocean
Arctic Ocean
But recently, scientists have added a fifth:
Southern Ocean. This ocean surrounds Antarctica and is known for its icy waters and unique marine life.

The ocean has inspired countless stories and legends. From pirates and mermaids to sea monsters and sunken treasure, the ocean has captured our imaginations for centuries.

Some parts of the ocean are called seas: a sea is like a smaller part of the ocean and it's surrounded by land, like the Mediterranean Sea.

All seas are salty. There are a few lakes that are salty and they are also called sea, like the Dead Sea, which is so salty that you can float on it.

Have you ever heard of the saying "Seven Seas"? It's a phrase that has been used for centuries to describe the vast oceans of our planet. The idea of the Seven Seas dates back to ancient times. Different cultures at different times have had their own list of Seven Seas. As explorers sailed farther and farther, the concept of the Seven Seas evolved and now the modern Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans.

While we think of seas as bodies of water, there's one special sea that doesn't have any water at all! The Sea of Tranquility is a dark, flat plain on the Moon. Ancient astronomers thought it looked like a sea, but it's actually a large volcanic plain.

Let's Protect Our Seas!

We need to take care of our seas.
You can help by:
Reducing plastic pollution: Say no to single-use plastics.
Conserving water: Use water wisely.

Let's keep our oceans clean and healthy!
