100 Amazing Facts About Planet Earth

Earth is the third planet from the Sun and is the largest of the terrestrial planets. Unlike the other planets in the solar system that are named after classic deities the Earth’s name comes from the Anglo-Saxon word erda which means ground or soil. The Earth was formed approximately 4.54 billion years ago and is the only known planet to support life.

100 Facts about the Earth :

  1. The Earth’s rotation is gradually slowing:

This deceleration is happening almost imperceptibly, at approximately 17 milliseconds per hundred years, although the rate at which it occurs is not perfectly uniform. This has the effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.

  1. The Earth was once believed to be the centre of the universe:

Due to the apparent movements of the Sun and planets in relation to their viewpoint, ancient scientists insisted that the Earth remained static, whilst other celestial bodies travelled in circular orbits around it. Eventually, the view that the Sun was at the centre of the universe was postulated by Copernicus, though this is also not the case.

  1. Earth has a powerful magnetic field:

This phenomenon is caused by the nickel-iron core of the planet, coupled with its rapid rotation. This field protects the Earth from the effects of solar wind.

  1. There is only one natural satellite of the planet Earth:

As a percentage of the size of the body it orbits, the Moon is the largest satellite of any planet in our solar system. In real terms, however, it is only the fifth largest natural satellite.

  1. Earth is the only planet not named after a god:

The other seven planets in our solar system are all named after Roman gods or goddesses. Although only Mercury, Venus, Mars, Jupiter and Saturn were named during ancient times, because they were visible to the naked eye, the Roman method of naming planets was retained after the discovery of Uranus and Neptune.

  1. Of all the planets in our solar system, the Earth has the greatest density:

This varies according to the part of the planet; for example, the metallic core is denser than the crust. The average density of the Earth is approximately 5.52 grams per cubic centimeter.

  1. 70% of the Earth’s surface is covered in water:

When astronauts first went into the space, they looked back at the Earth with human eyes for the first time, and called our home the Blue Planet. And it’s no surprise. 70% of our planet is covered with oceans. The remaining 30% is the solid ground, rising above sea level.

  1. Earth is mostly iron, oxygen and silicon:

If you could separate the Earth out into piles of material, you’d get 32.1 % iron, 30.1% oxygen, 15.1% silicon, and 13.9% magnesium. Of course, most of this iron is actually down at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. 47% of the Earth’s crust consists of oxygen.

  1. Earth doesn’t take 24 hours to rotate on its axis:

It’s actually 23 hours, 56 minutes and 4 seconds. This is the amount of time it takes for the Earth to completely rotate around its axis; astronomers call this a sidereal day. Now wait a second that means a day is 4 minutes shorter than we think it is. You’d think that time would add up, day by day, and within a few months, day would be night, and night would be day.

  1. A year on Earth isn’t 365 days:

It’s actually 365.2564 days. It’s this extra .2564 days that creates the need for leap years. That’s why we tack on an extra day in February every year divisible by 4 – 2004, 2008, etc – unless it’s divisible by 100 (1900, 2100, etc)… unless it’s divisible by 400 (1600, 2000, etc).

  1. Earth has 1 moon and 2 co-orbital satellites:

As you’re probably aware, Earth has 1 moon (The Moon). But did you know there are 2 additional asteroids locked into co-orbital orbits with Earth? They’re called 3753 Cruithne and 2002 AA29. We won’t go into too much detail about the Moon, I’m sure you’ve heard all about it. 3753 Cruithne is 5 km across, and sometimes called Earth’s second moon. It doesn’t actually orbit the Earth, but has a synchronized orbit with our home planet. It has an orbit that makes it look like it’s following the Earth in orbit, but it’s actually following its own, distinct path around the Sun.

12. The Earth is not actually round in shape; in fact it is geoid :

This simply means that the rounded shape has a slight bulge towards the equator. So what causes this geoid shape? This happens solely because the rotation of the Earth which causes the bulge around the equator.

  1. Only 3% water of the earth is fresh, rest 97% salted:

Of that 3%, over 2% is frozen in ice sheets and glaciers. Means less

than 1% fresh water is found in lakes, rivers and underground.

1OO. Plate tectonics keep the planet comfortable

Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.

This process is very important. When microscopic plants in the ocean die, they fall to the bottom of the ocean. Over long periods of time, the remnants of this life, rich in carbon, are carried back into the interior of the Earth and recycled. This pulls carbon out of the atmosphere, which

makes sure we don’t get a runaway greenhouse effect, like what happened on Venus.

Without the plate tectonics, there’d be no way to recycle this carbon, and the Earth would overheat.
