11 Little Known Facts About the Earth

Updated on November 8, 2014

Earth, it's where where we live, and as of now it's the only planet with life. However, how much do we know about this third planet from the sun? Test your knowledge to see how much you really know.

1. The name "Earth" actually comes from the Saxon word "Erda", which means ground or soil.

2. Unlike other planets, Earth is not named after Roman and Greek God or goddesses.

Mercury- God of travel.

Venus- Goddess of love.

Mars- God of war.

Jupiter-Top Roman God.

Saturn- Daughter of the first Roman God of agriculture. Her father was replaced by her.

Uranus- God of the sky.

Pluto-Not a planet anymore. Was the Roman God of the underworld.


3. The Earth's rotation is actually slowing. If humans, or even if Earth still exists in 140 million years, the length of a day will increase to 25-hours. So, if you just live long enough, there will be enough hours in a day to get all your Christmas shopping done.


4. Out of all the water on this planet, only 3% is fresh water.

5. The continents move 1.87centimeters each year.

6. Each day, Earth gets hit by over 110 tons of meteorites. Surprised? Me too. However, most of these meteorites are incredibly small, and a good majority of them go into the ocean.

7. You cannot see the Great Wall of China like my 5th grade teacher said, but you are able to see China's air pollution.

8. Depending on who you ask, or when you ask, but scientists today say through carbon dating that the Earth is 4.5 billion years old.

9. Humans are only able to mine less than 1% of the Earth's gold. Where's the rest of the gold? It's in the core of the earth.

10. Humans have only identified approximately 15% of the world's species. However, like my grandma said, "You don't know what you don't know". Maybe that estimated 15% is actually a smaller number. Many of these unknown species are located in the Amazon, and since it's being torn down at an alarming rate, many of these unknown species are going extinct.

11. Antarctica holds as much water as there is in the Atlantic Ocean. Also, there is land under Antarctica.

      Not bad. It's fun learning about the earth's history. I like thinking about the accretion disk that formed it in the first place.
