Planet Earth. That beautiful, shiny blue marble has fascinated humanity since they first began to run across its surface. And why shouldn’t it fascinate us? In addition to being our home and the place where life as we all know it originated, it remains the sole planet we know of where life thrives. Over the course of the past few centuries, we've learned a lot regarding the Earth, and that has solely focused our fascination with it. To know more about the earth, read these facts till the end.
1 - Earth’s continents were once called Rodinia.
We know—you’ve detected Pangea, not Rodinia. However, bear with us for a moment—800 million years ago, the Earth's tectonic plates collided, uniting all of the continents, and this was known as Rodinia. It eventually stone-broke apart and re-collided, which resulted in the formation of the Appalachians in North America and the Ural Mountains in Russia and Kazakhstan.
2 - Earth is sort of a sphere.
Many people tend to suppose that the world could be a sphere. In fact, between the sixth century BCE and the epoch, this remained the scientific order. However, in popular natural philosophy and spaceflight, scientists have discovered that the world is actually shaped like a planar sphere (also known as an oblate spheroid). This form is comparable to a sphere.
3 - The times are becoming longer.
The length of the Earth's day is increasing. A day on Earth 4.6 billion years ago would have been about six hours long. By 620 million years ago, this had redoubled to twenty-one. Today, the typical day is twenty-four hours long, but it is increasing by 1.7 milliseconds each century. The reason? The moon's swiftness slows Earth's rotation through the tides that it helps produce. Earth's spin causes the position of its periodic ocean bulges to be forced slightly prior to the moon-Earth axis, creating a twisting force that slows down Earth's rotation. As a result, our day is getting longer — but not long enough to create a distinction from your busy schedule.
4 - Iron, Oxygen, and Silicon are the most common elements on Earth.
If you separated the world out into piles of material, you will get 30.1% oxygen, 32.1 iron, magnesium is 13.9% and silicon is 15.1%. Of course, the majority of this iron is truly settled at the world's core. If you really get down and sample the core, it might be half a mile of iron. And if you sampled the Earth’s crust, you’d realize that 47% is oxygen.

5 - The World Recycles Itself.
Earth is the only planet in our system that has plate tectonics. As they collide and pull apart, stone bubbles up and creates a contemporary crust. This necessary method creates mountain formations, volcanic eruptions, ocean trenches and earthquakes. However, it is also a part of the carbon cycle, within which microscopic organisms and plants die, fall to the rock bottom of the ocean wherever they're absorbed, and, over long periods of time, the remnants of this life, wealthy in carbon, are carried into the inside of the world and recycled.
6 - Earth is accustomed to being purple... apparently.
Some experts believe that the earth could be purple at one point in time. Refueling that fireside is the undeniable fact that ancient microbes could have relied on a special molecule apart from the inexperienced pigment to grab the sun’s rays. Instead, that molecule retinal could have created things we all know as inexperienced nowadays, looking a lot like purple.
7 - Earth's gravity is not uniform.
Earth fields would be constant everywhere. However, essentially, the planet's surface is rough, and water flow, ice drift, and the movement of the tectonic plates to a lower part of the Earth's crust all modify the pull of gravity. These variations are called "gravitational anomalies." A range like the range causes a positive gravity anomaly, which means gravity is stronger there than it would be on a regular dead smooth planet. Conversely, the presence of ocean trenches, or dips in the land caused by glaciers millennia ago, results in negative gravity anomalies. NASA's GRACE (Gravity Recovery and Climate Experiment) mission, orbiting on top of us, is mapping Earth's fields in unprecedented detail.
8 - Humans could weigh in otherwise, looking on wherever they stand.
Live Science says if you weighed yourself at the equator, you'd weigh less than if you weighed yourself at one of Earth’s poles. However, not by a lot. Your weight at the equator would doubtless be approximately 0.5 p.c. at the poles.
9 - The world’s largest tree is that of General Sherman.
The General Sherman tree, a giant sequoia tree settled in the national park in California, is 52,500 feet in volume and over 2,000 years old. The final Sherman Sequoiadendron giganteum is the largest glorious stem tree by volume in the world and the trunk of the tree contains slightly is 52,500 cubic feet (1,486.6 cubic meters) of material.
10 - Earth Doesn’t Take Twenty-Four Hours to Rotate on its Axis.
The world truly rotates once on its axis in twenty-three hours, fifty-six minutes, and four seconds. That's what astronomers refer to as a unit of time. We're still waiting for a second. Doesn’t that mean that on a daily basis it is four minutes shorter than we expect it to be? You’d think that now it would add up, day by day, and within a couple of months, day would be night, and night would be day. However, keep in mind that the world orbits around the Sun. Every day, the Sun moves compared to the background stars by 1 degree—regarding the scale of the Moon in the sky. And so, if you add up that small motion from the Sun that we tend to see as a result of the world orbiting around it, in addition to the rotation on its axis, you get a complete twenty-four hours.
