Chinese Researchers Discover Earth's Mantle Stored Ancient Oceans

Scientists in China found out how Earth might have stored a lot of water a long time ago.

They discovered that a special rock called bridgmanite in the deep part of Earth, called the mantle, can hold water.

This happened when Earth was very hot and had oceans of magma.

The scientists did experiments to show that bridgmanite can trap water, especially when it's very hot.

This water was stored deep inside Earth and slowly came back to the surface through volcanoes over billions of years, making our planet habitable.

This helps us understand how Earth became the blue, watery world we live on today.
