What is water?

1. Water molecules are made up of two chemical elements: hydrogen and oxygen.

Forming water

2. Scientists think that water formed with the creation of Earth in the Solar System. Asteroids from outer space collided into the Earth’s surface, releasing the water as a gas that became trapped in the atmosphere.

Ancient water

3. Water found on Earth today has been here for billions of years! It is constantly recycled in the water cycle, where water from oceans and lakes turn into clouds before falling as rain or snow.

People: more water than not!

4. Water isn’t just found in oceans and rivers, but in people too! The human body is made up of 65% water.

Icy Moon

5. A team of NASA scientists have discovered evidence of water ice on the surface of the Moon!
