10 amazing little-known facts about the Earth

To learn something new about our planet is an unusual experience. Sometimes it makes you look at the world in a completely new way. For centuries, people have dedicated their lives to learning how the Earth functions. Sometimes we do not think about what we breathe and what we drink, because we are too busy with our daily affairs. However, it will never be superfluous to take a moment to learn some interesting facts about the planet Earth.

1. The longest mountain range on Earth extends more than 70 thousand km and is under water.
 

It is called the Mid-oceanic ridge.

2. More than half of the Earth’s water masses are concentrated in the Pacific Ocean.
 

 
The Pacific Ocean is the largest ocean of the planet, and it contains half of all the unfrozen water masses of the Earth.

3. The world’s ocean is so deep that it was investigated by people only by 5%.
 

 
Despite all the existing technologies, most of the ocean floor of the planet can not be investigated because the water interferes with the passage of radio waves. In fact, scientists can create a more accurate map of Mars, the Moon and Venus, rather than the ocean floor.

4. In the deepest place in the world visited only 3 people, while at the highest point of the planet – 3 thousand people.
 

 
The deepest part of the Mariana Trench is called the Challenger Abyss and reaches 10 971 m in depth. Only 3 people visited the Abyss, and director James Cameron is one of them. But on Everest – the highest point of the planet – visited 3100 people. Unfortunately, about 220 climbers died, trying to reach the top of the mountain.

5. Perhaps in the past, because of ancient microbes, the Earth was purple in color.
 

 
If you look at the Earth from space, you can see that it is blue with interspersed with green. However, one scientist claims that many years ago the Earth could have a purple color because of ancient microbes that absorb solar energy, using retinal instead of chlorophylls (pigments, through which plants acquire a green color). Retinal absorbs green light, which accounts for most of the solar energy, and reflects the violet and red light. Because of this combination, Earth from space could seem purple.

6. Gravity acts in different ways in different corners of the planet.
 

 
The earth is constantly moving, and because of this, gravity operates differently everywhere, and at the poles you would weigh a little more than at the equator.

7. In Antarctica, 90% of all ice on Earth and 70% of all water are concentrated.
 

 
8. Annually, 1 million billion cubic feet of snow falls on the Earth.
 

 
This number is 15 zeros. Weigh all this charm of a million billion kilograms.

9. Antarctica is the driest place on earth.
 

 
There has been no rain for 2 million years.

10. Thanks to earthquakes, gold is formed.
 

 
When an earthquake occurs, the water inside the fault evaporates and mixes with the silicon oxide, resulting in gold. Unfortunately, for a sufficient amount of gold to form, at least 100,000 years must pass.
