Hi everyone,
We think we know everything about our home planet, but we couldn’t be more wrong. Scientists have already discovered a lot about the Universe, but they believe there is still much more to learn about our planet. You’ll be amazed when you find out how much you have yet to learn about our home planet, let’s start with 45 unknown earth facts.

Summary:
1. There weren't always several continents
2. Some 300 million years ago, there was just one continent. A massive
supercontinent called Pangaea. And thus, there was just one giant sea,
called Panthalassa.
3. Our solar system is 4.57 billion years old.
4. Researches calculate that the earth is approximately 4.54 billion years old,
that is insanely old.
5. The earth is approximately 93 million miles (150million kilometres) from
the Sun. It makes about 8 minutes and 19 seconds for sunlight to reach our
planet.
6. Earth's gravity isn't uniform
7. Because of imbalance gravity/centrifugal force at the equator coupled with
the speed that the earth is spinning. Our planet is not a perfect sphere. it is
slightly bulging out in the middle.

9. Our poles switch. our planet has settled into a pattern of a pole reversal
about every 2,00,000 to 3,00,000 years.
10.The circumference of the globe is 24,901 miles (40,075 kilometres)
11.The earth isn't just spinning in place, its zipping around the sun at a rate of
67,000miles (107.826 kilometres) per hour.
12. Earth's icy times
13. In the past, sea levels were very different
14.The days are getting longer.
15.At the equator, you would weigh less than if standing at one of the poles.
16.Depending on where you are on the globe, you could be spinning through
the space at just over 1,000 miles per hour.
17.Hudson Bay, Canada, has lower gravity than other regions of the earth.
18.The Pacific Ocean is huge; it covers an area of about 59 million square
miles (155 million square kilometres) and containing more than the half of
the free water on earth.
21.Coral reefs support the most species per unit. Area of any of the planet's
ecosystems, rivalling rain forests.
22.Researchers believe that at one point, we had two moons. our second moon would have been about 750 miles orbited the earth in the past.
23.We always see the same side of the Moon, no matter where we stand on Earth.
24.The moon is not Earth's only companion
25.The lowest point on earth that is ' on land' is the dead sea
26.The driest place on Earth
27.El Aziziya, Libya holds the record for the hottest place on earth. According
to NASA, it hit 136 degrees Fahrenheit (57.8 degrees Celsius) on
September 13, 1922.
28.The lowest temperature ever recorded on earth came from Russia's Vostok station
29.The calm before the storm
30.A single stroke of lightning can heat the air to around 54,000 degrees
31.Our sun has a voracious appetite
32.Only 5% of the universe is visible from Earth.
33.Earth is one of the four terrestrial planets: like Mercury, Venus, and Mars. It is rocky at the surface.
34.In our solar system that are 4 planets known as gas giants: Jupiter, Saturn, Uranus & Neptune.
35. Mercury & Venus are the only 2 planets in our solar system that have no moons.
37.The hottest planet in the solar system is Venus with an average temperature
of 464 degree Celsius
38. The coldest planet in the solar system is Pluto with an average
temperature of -225 degree Celsius.
39.The Sun weighs about 330,000 times more than Earth.
41.Pluto is smaller than the United States
