Water is all around us; in fact, many of us can go turn on the tap and get fresh water right now! While water is around us all the time, there’s probably a lot you don’t know about it. Check out these fun water facts below!
Water covers about 71% of the earth!
No wonder they call it the Blue Planet. Most of the earth is covered in oceans, and a small portion of lakes, rivers, and streams. That’s a lot of water!
Life cannot exist without water.
All of the life on our planet is supported by water– even in ecosystems that are extremely dry, like the desert!
All of the water on earth is linked in a vast cycle.
This means that the water coming out of your sink could have been rain at one point, or might even have been in the ocean! As water evaporates, freezes, melts, and flows, it can go through many different forms and locations.
97% of the earth’s water is salty.
That means only 3% of the water on earth is freshwater, or water without salt in it! All the water in our oceans, and sometimes other bodies of water is salt water.
Water can be used for energy.
We can use bodies of water to create other sources of energy, such as electricity! Machines like water wheels and dams have engineered ways to make bodies of water create sources of energy.
Ice is lighter than water!
When water freezes, it becomes ice. Ice becomes less dense and therefore lighter than water, which is why icebergs float in the ocean, and even little pieces of ice will float in your cup of ice water!
75% of our brains are made up of water.
Our brains need a lot of water to keep working well– that’s a good reason to stay hydrated!
Water = H2O
Water is composed of two hydrogen atoms and one oxygen atom fused together. That’s why it’s often referred to as H2O!
We hope you enjoyed learning all these fun water facts! Water is super important and is a precious resource. Let’s enjoy it!
