2021-earth-day-30-fascinating-facts-that-will-raise-your-awareness-related-to-environmental-issues

On April 22, Earth Day will be celebrated all over the world - a holiday in which it is worth thinking about the future of our planet and what we can do for a common home. This tradition originated in 1970 at the initiative of US Senator Gaylord Nelson, whose goal was to draw public attention to the problems of environmental pollution. On the eve of the holiday, we will share with you the most interesting facts about the Earth.


Earth Day was founded by US Senator Gaylord Nelson in 1970 to awaken the political class from its disinterest in the environment and was celebrated in its first year by about 20 million Americans, mostly young people. and very young. After 2 decades, in 1990, over 200 million people in 141 countries turned Earth Day into a major event in human history, by joining them in the desire to advocate for a better future for our planet, and in year 2009,


The United Nations (UN) has declared April 22 as the official holiday of planet Earth and a common expression of everyone's desire to build a stable society for a cleaner and greener future. The genesis of the Earth took place several billion years ago from a cloud of dust and gas that revolved around the sun and is the third planet from the sun with a particular constitution in the solar system.


Bemorepanda collected some interesting facts for you.


1. The core of the Earth contains so much gold, which will be enough to cover the entire surface of our planet by almost 45 centimeters.


2. The inner core of the Earth has a radius of about 1220 kilometers, which is comparable to 70% of the radius of the Moon. In addition, based on geophysical and geochemical methods, there is an assumption that the inner core of our planet is about the same temperature as the Sun.


3. Lightning strikes the earth on our planet more than 8.6 million times a day.


4. Prior to space travel, the Earth was often depicted as a green world. Science fiction writer Frank Paul is believed to be the first to depict a cloudless blue planet with well-defined land on the back of the July 1940 issue of Amazing Stories magazine.


5. Scientific evidence indicates that the Earth was formed from a solar nebula about 4.54 billion years ago. Life on the planet appeared about 4.25 billion years ago, that is, shortly after its origin.


6. The conditions for the existence of life on Earth preserve the ozone layer and the Earth's magnetic field, which weaken the solar radiation harmful to life.


7. The oceans occupy about 70.8% of the surface of our planet. Liquid water, which is essential for all known life forms, does not exist on the surface of any known planet in the solar system other than Earth.


8. The average speed of movement of lithospheric plates on Earth is approximately equal to the growth rate of nails on human hands. After 200-300 million years, hypothetically, all the continents of the planet will merge into the supercontinent Pangea Ultima.


9. The force of gravity at the poles of the Earth is greater than at the equator. A person who weighs 150.8 pounds (68.4 kg) at the North Pole will weigh 400 grams less while at the equator.


10. More than 68% of the Earth's freshwater is solid, including glaciers, snow cover and permafrost. 


11. The Earth was first photographed from space in 1959 by the Explorer-6 apparatus. The first ever image of the entire Earth was captured by the orbital station Lunar Orbiter V on August 8, 1967.


12. The most massive extinction in the entire history of the Earth occurred at the end of the Permian period (298.9 ± 0.15 million years ago), when more than 90% of living things on the planet died.


13. The highest point on the Earth's surface is Mount Everest (8,848 m above sea level), and the deepest is the Mariana Trench (10,994 m below sea level).


14. The deadliest tsunami known to have occurred on 26 December 2004 in Southeast Asia was triggered by a 9.3 magnitude submarine earthquake in the Indian Ocean. The total death toll exceeded 235 thousand people.


15. The most toxic plant on Earth is the yew, a genus of small conifers. Every part of this tree is poisonous, with the exception of its berries, however, their seeds are also poisonous.


16. If all the water of the World Ocean is evenly distributed over the surface, then a layer with a thickness of more than 2.7 kilometers would be obtained. Of all the water that is on Earth, only 2.5% is fresh, the rest is salty.


17. Without the greenhouse effect, the Earth's average temperature would be between -18 and -23 ° C, given that it is actually 14.8 ° C. Without this thermal insulation effect, life on our planet most likely would not exist.


18. The atmosphere passes into interplanetary space gradually, in the exosphere, starting at an altitude of 500-1000 kilometers from the Earth's surface. By definition, the boundary between the atmosphere and space is drawn along the Karman line, located at an altitude of about 100 kilometers, above which air flights become completely impossible.


19. Human breathing becomes impossible at an altitude of 9 kilometers, although the atmosphere contains oxygen up to about 115 kilometers.


20. At an altitude of about 19-20 kilometers, the pressure of the atmosphere decreases so much that it leads to the boiling of water and interstitial fluid in the human body. Outside the pressurized cockpit at these heights, death occurs almost instantly.


21. The seas lose more water due to evaporation than they receive with precipitation, on land - vice versa. Water circulates continuously around the globe, while its total amount remains unchanged.


22. The rotation of the Earth occurs from west to east. Due to tidal acceleration, each next day is longer than the previous ones by an average of 29 nanoseconds.


23. Due to tidal synchronization, the Moon is moving away from the Earth by about 38 millimeters per year. Millions of years from now, this tiny change, as well as an increase in Earth's day of 23 microseconds per year, will result in significant changes. So, for example, in the Devonian period (about 410 million years ago) there were 400 days a year, and a day lasted 21.8 hours.


24. The largest tidal waves on Earth are observed in the Bay of Fundy in Canada and are 18 meters.


25. Earth is the only name for the planet that was not taken from Greco-Roman mythology.


26. Lake Baikal in Russia accounts for about 20% of all world reserves of fresh lake water. It is the deepest and oldest lake in the world.


27. The ice sheet in Antarctica contains about 80% of all freshwater on the planet. If it melts completely, the level of the World Ocean will rise by almost 60 meters.


28. The Earth moves around the Sun at a distance of about 150 million kilometers at a speed of almost 30 kilometers per second.


29. The driest place on earth is the Atacama Desert in Chile. In some places of this desert, rain falls once every several decades.


30. If the history of the Earth were presented in the form of a 24-hour segment, then the dinosaurs would have died out at 23:41, and human existence would begin at 23:54 and 43 seconds of the same day.
