10 Things You Never Knew About The Earth


10 amazing things you didn’t know about the
Earth 10. Secret ocean Scientists have discovered a vast reservoir
of water located 660 kilometers beneath the Earth’s surface. The underground ocean is hidden inside a blue
rock called ringwoodite, which acts like a sponge, trapping hydrogen and
water. There is enough water beneath the Earth’s
surface to fill the Earth’s oceans three times over. Scientist Steve Jacobsen suggests that the
Earth’s surface oceans were first formed when trapped water was driven to the
surface by geological activity. This contradicts the widely accepted theory that
icy comets deposited water onto Earth. Sources: The Guardian, New Scientist 9. Uneven gravity Many people assume that gravity is distributed
evenly on Earth, but there are certain places, such as Hudson Bay in Canada,
that actually experience less gravity than other regions of the globe. In Hudson Bay this occurs because there is
only a small amount of land mass, due to retreating glaciers on the surface
and swirling magma in the Earth’s core. A satellite called the ‘Gravity Field and
Steady-State Ocean Circulation Explorer’ was sent into space in 2009 to create a map
of the planet’s gravitational field. It mapped Earth’s gravity with extraordinary
accuracy and is used by geophysicists to measure ocean circulation,
sea-level change, and ice dynamics. Sources: Live Science, New Scientist, Space
Daily 8. Longer Earth days Around 620 million years ago, there were only
21.9 hours in a day. Ocean tides generated by the Moon and Sun’s
gravity have added 1.7 milliseconds to the length of a day each century,
because they alter the planet’s rotational momentum. The length of the day can also be affected
by natural events such as the 2011 earthquake in Japan, which actually shortened
the length of each Earth day. The quake changed the distribution of the
Earth’s mass causing it to rotate slightly faster, decreasing our day by about
1.8 microseconds. Sources: Scientific American, NASA 7. Pangaea Pangaea was a supercontinent that existed
during the late Paleozoic and early Mesozoic eras, 300 million years ago. Formed by the movement of Earth’s tectonic
plates, it began to break apart about 175 million years ago. At this time most of the dry land on Earth
was joined in one huge land mass that covered nearly a third of the planet’s surface. Geologists believe that due to tectonic plate
movements, in 250 million years the Earth’s continents will be merged again
into one giant land mass, form ‘Pangaea Ultima.’ Currently each year Hawaii, which sits on
the Pacific Plate, moves nearly three inches closer to Alaska. Sources: Universe Today, BBC, The Blaze 6. Hot in here Over the next 1.1 billion years, scientists
predict that the Sun will get progressively brighter and hotter by about
10% compared to now. In 4 billion years, our oceans will evaporate,
resulting in a runaway greenhouse effect that will send temperatures soaring
above 750 degrees Fahrenheit, rendering life on Earth impossible. In 7.5 billion years, Earth will become a
vast desert similar to Mars today and the Sun will expand into a red giant. At this point, scientists predict that the
Sun will engulf Earth altogether, meaning the definite end of our planet. Sources: Howitworksdaily, BBC 5. Earth used to be purple There is an astrobiological hypothesis that
suggests that Earth used to be purple. Scientists believe that before plants as we
know them became dominant, ancient microbes might have used a molecule other
than chlorophyll to harness the Sun’s rays. The molecule, called retinal, gave Earth’s
organisms a violet hue. According to Shil DasSarma, a microbial geneticist
from the University of Maryland, chlorophyll gradually replaced retinal
because it is more efficient at absorbing light, and thus purple became green. Sources: Astrobio, livescience, Dawn 4. How did life on Earth begin? There are around 8.7 million different species
on Earth, but scientists are still not entirely sure how life on Earth began. Most scientists believe that living things
developed from molecules that were able to replicate themselves, rather like
DNA does. These molecules either came from somewhere
further out in space, or they were produced by the conditions on Earth at the
time. A new study suggests the latter and argues
that the building blocks of life, such as the compounds that would be necessary to
create DNA, existed on Earth prior to the creation of the first life forms. Sources: BBC, Live Science, Time, Phys.org 3. Earth is a bumpy globe Despite countless photos of Earth depicted
as a perfect sphere, Planet Earth is actually an imperfect bumpy globe. This is because the force of Earth’s rapid
rotation on its axis causes it to push outwards at the equator, making it look like
a squashed ball. Due to the Earth’s uneven shape, Mount Everest
isn’t actually the tallest mountain. If measured from sea level, Everest
would top the list, but measuring from the center of the Earth, Mount Chimborazo
takes the crown. Sources: Scientific American, Independent 2. Underwater mountain range The longest mountain range on Earth is actually
90% underwater. It is called the mid-ocean ridge system and was formed by the
movement of plate tectonics. Surveyed in detail in the 1950s, it stretches
for 80,000 kilometers all around the world and is nearly 20 times longer than the
longest range on the surface, the Andes Mountains. Furthermore, it consists of thousands of individual
volcanoes that sporadically erupt. Around 20 volcanic eruptions occur each year
and this causes the formation of 2.5 kilometers of new seafloor. Sources: BBC, Ocean Service 1. Geomagnetic Reversal The Earth’s magnetic field is becoming less
stable. Researchers believe that the planet’s inner
core is slowly growing, as the outer core cools and solidifies, resulting in more
frequent flips of Earth’s magnetic field. In other words, if the polarity of today’s
magnetic field were reversed, the North and South markings on all compasses would
be 180 degrees wrong. Using fossil records from hundreds of past
magnetic polarity reversals, scientists have determined that the reversal of the magnetic
poles should not have a dramatic effect on human life. However, some animals, such as pigeons and
whales, use the Earth’s magnetic field for a sense of direction. So, if a reversal
occurs in their lifetime, they might have to develop different methods of navigation. Sources: NASA, geomag, BBC

  1. We are not and never have been a 'magma planet'. We are a water sphere. We have plenty of water. If we were a magma planet then the deeper you went in the oceans the warmer it would get. What we call magma is created from the movement of the Earth. The friction of the crust liquifies under intense pressure and movement which when released brings pure mineral content that has been purified by frictional heat. Check out the Universal Model by Dean Sessions. We have been lied to. Progress is for mankind, not for the elitist alone. This millennium is an age of revealing truths!

  2. The magma is caused by extreme pressure under the crust of earth meaning that the underground ocean would not exist and if it did there would be a major fault line underneath the crust and a large volcano where the "secret ocean would be " and if it did exist now there would be a large explosion causing the earths crust to fracture and we would all be dead.

  4. How about using the energy stored in the carbon inside diamonds. For clean fuel on earth.👍🙌👈👽👏

  5. Lmao more nonsense from atheist idiots who claim to be “scientist” lol just evolution! Bunch of dumb theories with zero evidence. Yet they ignore the truth which has all the evidence any person would ever need. Blows my mind so many ppl in this world are so gullible to believe the bs that comes outta scientists mouth and the load of crap they teach in schools. Anyone with a brain can find the truth themselves and stop being sheep just believing morons like this!

  6. It's almost unbelievable that you can measure Hawaii moving 3 inches a year….. in fact I literally don't believe it.

  7. If there was an ocean near the inner core it would evaporate instantly since the inner core of the earth is hotter than the surface of the sun.

  8. And people actually believe this.smh, who put these theories together?, Wait I know a bunch of atheist scientist.

  9. Pick out and slam theories of others together, make a youtube. Theory is only a guess until actual truth is discovered proven.

  10. Crazy live there and put stupid basless videos on youtube to make money from other conspiracy nut cases!

    I KNEW THAT

  11. very good bedtime story…watch something real https://www.youtube.com/watch?v=BhSHrX3Wo_w&t=1s

  12. HOG WASH, the earth was created by God you morons.

    (Genesis 1:1)

    In the beginning God created the heavens and earth.

    Stick that in your pipe and smoke it you IDIOTS.

  13. Speculations. They never went past 5 miles in depth. They can say the core is made of cheese and nobody can prove them wrong nore can they prove themselves right

  14. Scientists still unsure about how life began on earth, someone please give scientists a bible🤣🤣🤣

  15. Scientists have great faith since the believe in lot of things. They are even determined that things happened in a certain way. Are they not supposed to base their theory on knowledge and experience……
    They still cannot explain the origin of life. Life is the most important question of humankind. How did those scientist come into existence ?? Do not fool people so cheaply !!
    I know a lot of them believe in God.

  16. this guy, for example, said "the earth used to be purple, a theory from scientists says…." a theory is an assumption

  17. This water issue is described in the bible and explained the FLOOD !!!  Genesis 7:11. “Fountains of the deep” is used in Genesis 8:2, where it clearly refers to the same thing,

  18. Crick , as in Watson and Crick, together with Hoyle realized that it is mathematically impossible for molecules to organize themselves into life. But predetermined not to believe in God , postulated ( decided to believe) that life was actually seeded on earth by extraterrestrials. Theory of Panspermia !

  19. dude.. seriously? anyone who didnt realize the earth wasnt a perfect sphere is (im sorry to say, but) unimaginabley stupid.. with all the mountains and valleys and such..i mean, come on now ..-_-;

  20. Omg all these people saying, "Oh I knew about Pangea." …. The main focus was the recreation of Pangea, Pangea Ultima, not the original Pangea. Please stop.

  21. According to our book (Exploring life through Science Series) grade 10 from Phoenix publishing house, 2:34 which means "the last Pangaea was later decided to change it to Pangea Proxima "The Next Pangea"

    – in case someone don't know yet

  22. It would be beautiful to live in Pangea Ultima…😊❤ all countries becoming one with zero language barriers! Very fortunate and blessed people will be there!
    Ps… human life on earth will never finish! Because is meant to be!

  23. SO….Does that mean the Great Flood from the Holy Bible is possible? 7:11 on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. 12 And rain fell on the earth forty days and forty nights.

  24. Unless God desired for there to be life on other planets, then Earth is all she wrote. ISAIAH 45 verse 18.

  25. The underground Ocean is propably there to keep gog and magog alive, its a Nation which will come out on the day of judgement

  26. Most of this is al fiction, 300.0000 years ago.
    1.5 billion years from now blablabla 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

  27. Btw oceans cant be inside the core so thumbnail is fake and water was brung by (not comets) asteroids that had water on them

  28. WAtch Lunar Eclipse – 17th July 2019 – Filmed in Perth, Western Australia

    https://www.youtube.com/watch?v=VHOS5s9UM48&t=247s

  29. the height of mount everest is counted from above sea level because that is basically the definition for height for such land forms but how tall something is can be from below sea level which caneven be from the center of the earth, so everest is bested by another mountain called mauna kea in hawaii, sooooooooo, i think he meant it is tne highest but not the tallest, p.s i am 11

  30. We are not able to tell exactly how old the pyramids of Giza are but we can to talk about what happened billions of years ago and will happen in billions of years.
