🌊 Ocean
Exploring the wonder of an ocean!
An Ocean is a huge body of salty water that covers most of the Earth.
🌍 What Is an Ocean?
An ocean is a huge body of salt water. Earth has five oceans: the Pacific, Atlantic, Indian, Southern and Arctic Oceans, all connected to each other. Wind pushes the water into waves and currents, and the pull of the Moon's gravity causes the tides. Sunlight only reaches the top part, so the deep ocean is dark and cold.
🌟 Fun Facts about Ocean
- Oceans cover more than 70% of the entire Earth’s surface.
- The deepest part of the ocean, the Mariana Trench, is deeper than Mount Everest is tall!
- Oceans are home to amazing creatures like whales, dolphins, and colorful coral reefs.
- Ocean water is salty because rivers carry tiny bits of salt from rocks into the sea.
🔎 Where to See an Ocean
You can see the ocean from beaches and harbors, and aquariums let you meet ocean animals up close. In rock pools at low tide, look for starfish, crabs and sea anemones. Scientists use special submarines to explore the deep ocean, where there are still animals no one has ever seen.
