Top 10 facts about water.
Hello!
Many of us think that water originated on our earth but did you know a fact that it is suggested that water came to our earth when a huge icy rock crashed into the earth. Scientists have discovered that there is not only water on our earth but also in outer space.
Water is essential for all life on earth. All living things, be it under the sea or living in the desert, cannot survive without water. Water is what makes Earth habitable. Because of this, scientists say that searching for water in space could help us find life.
We will find some interesting information about this water in this post.
How old is the water?
It's a mystery how the world became awash in it. But one prevailing theory says that water originated on our planet from ice specks floating in a cosmic cloud before our sun was set ablaze, more than 4.6 billion years ago.
How much water is there?
About 96.5 percent of Earth's water is in our oceans, which cover 71 percent of our planet's surface.
Only 3.5 percent of our Earth's water is pure water. You'll find Earth's fresh water in lakes, rivers, and streams, but don't forget groundwater and glaciers. More than 68 percent of Earth's fresh water is locked in groundwater and glaciers.
salt water
An average gallon of seawater contains about 1 cup of salt. But it varies from sea to sea. For example, the Atlantic Ocean is more saline than the Pacific Ocean. Most of the salt in the ocean is the same type of salt we put in our food: sodium chloride. The world's saltiest water is found in a small lake called Don Juan Pond in Antarctica
Human Body
A newborn baby's body is 78 percent water. An adult's body is 55-60 percent water. Water plays a role in everything our body does. It is part of the blood that brings nutrients to all our cells. It is used to eliminate waste and it helps regulate our body temperature.
Molecules
The number of molecules in a glass of water you drink is the same as the number of molecules in the ocean.
Hot Water
You would think that hot water would take longer to cool, but in fact, hot water freezes much faster than normal water.
Sea Water
In this world there is a project in Dubai to recycle sea water and turn it into drinking water. Because there are no rivers in Dubai. Moreover, studies indicate that 85% of the world's population lives in deserts.
Cost of water
The world uses 36,000 liters of water per day just to make cloth and textiles. This is equivalent to the amount of water used in a city per day.
Space Water
If you think that only water exists on our earth, it is not true. Besides our Earth, the Moon and Mars also have water ice, researchers say. Apart from this it is also said that water floats in space.
Is Earth losing water?
Water flows endlessly between the ocean, atmosphere, and land. Earth's water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
