Five Jaw-Dropping Facts About the Earth You’ve Never Heard of
In our day-to-day life, we encounter many unusual phenomena, but we never wonder what, how & why it is happening. Let’s take an example of the planet on which we live, the Earth. It’s full of breathtaking events about them you might haven’t given a passing thought ever. Have you ever wondered why it is called the blue planet? Or why does it appear bright when looking upon from a distant place in space? If you are now scratching your head, then stop letting your mind wander. Read this deeply researched piece of content to know some brilliant facts about your own so-called planet ‘ the Earth.’ Take a look!
Fact-1: Why does it look so heavy?
- In the solar system, Earth is the densest planet with a density of approximately 5.52 grams per cubic centimeter. Mercury follows it with a density value of nearly 5.427 grams per cubic centimeter.
- It’s shocking, but true at the same time that the Earth weighs nearly 5,974,000,000,000,000,000,000,000 kilograms. To understand this more simply, one can say that Earth’s weight is approximately equals to that of 54,807,339,449,541,284,403 blue whales.
Fact-2: Does it really take 24 hours to complete a revolution?
- If you think that a year on Earth comprises 365 days, then this isn’t true. The actual figure is 365.2564 days. This extra 0.2564 day is the reason why we have a leap year after every four years.
- You might not be aware of this fact that the rotation of our Earth is gradually downshifting. The pace of which is very minimal, i.e., approximately 17 milliseconds per hundred years. That means after 140 million years from now, a day will have 25 hours.
Fact-3: Why is it called the ‘Earth’?
- This might make you a bit astonished that Earth is the only planet in the solar system which is not named after either a Greek or Roman God or Goddess.
- The word "Earth" is derived from both German and English, 'erde' and 'eor(th)e/ertha,' respectively, which means ‘ground.’
Fact-4: What is so unusual about its layers?
- The Earth comprises 3 layers with totally different composition: the crust, mantle, and core.
- The mantle is the thickest layer of Earth and contributes to 84% of the total volume of Earth.
- The Earth’s core is as hot as the sun and made up of two layers, the outer and inner layer. And, their specific percentages in the overall core are still unknown.
- The Earth’s core inherits Nickel and Iron, which when accompanying the Earth’s rotation produce a powerful magnetic field that protects this planet from the dreadful effects of solar winds.
Fact-5: Why is it the brightest planet in the solar system?
- People call Earth the Blue Planet because its 70% surface is covered with water. But, out of that only 3% is fresh water, whereas the remaining 97% is salted.
- Earth is the only planet in our solar system to have water in all three of its forms (Liquid, Solis & Gas).
- When sun rays strike the moving water covering the Earth, they get reflected and make this planet one of the brightest planets to look upon from a distant point in space.
Earth is not only full of elements, precious gems, and diamonds, but it is also full of mysteries and associated with many facts. Hope you liked reading the blog.
