25 Interesting Facts About Our Planet Earth
- Dec 03, 2017
Our home, Earth, is the 3rd planet in the solar system and is the only world known to man to support an atmosphere of oxygen, liquid water, and more importantly, life. Read on to know about a few more unusual facts about our planet that you may not have heard of yet.
The Earth’s rotation is gradually decreasing at an average rate of 17 milliseconds per hundred years.
Although this rate is not completely uniform and varies substantially from centuries to centuries, the point is we are slowing down with each passing minute.
The Earth is not a perfect sphere. It is geoid in shape.
The Earth has a powerful magnetic field created by the iron and nickel core of the planet. This magnetic field protects our planet from the destructive effects of the solar winds.
Note: The magnetic field of the Earth is on the verge of decline.
The Earth moves around the sun at an incredible speed of 67,000 miles per hour.
The Earth is the densest planet in our solar system.
Unlike Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, the Earth is the only planet that is not named after a God.
The ground you are walking on is recycled periodically by the Earth’s rock cycle phenomenon.
The rock cycle of the Earth transforms igneous rocks to sedimentary to metamorphic and back again. This cycle isn’t perfect by any means, but it happens for sure.
The Earth has only one satellite, the moon. Based on the size of our planet and that of the moon, we can say that the moon is relatively the largest satellite of any planet in the solar system.
Once upon a time, the Earth was believed to be the center of the universe. Ancient scientists believed that the Earth was static and the other planets and the sun revolved around it.
Although the moon looks rather inactive and dead, moonquakes (“quakes” on the moon) are a common phenomenon.
The hottest spot of the Earth lies in Libya where temperature records revealed that it hit 57.7 degree Celsius (136 degrees of Fahrenheit) on September 13, 1922.
The Earth does not take 24 hours to complete a rotation. It takes 23 hours, 56 minutes, and 4 seconds.
The Earth doesn’t exactly take 365 days to complete a revolution. It is actually 365.2564 days. That extra period of 0.2564 days plays a mighty important role in the creation of leap years.
The Earth’s tilt is roughly at 66 degrees to the normal.
The Antarctica is the coldest place on the Earth with temperatures dropping below -100 degrees of Fahrenheit.
30% of the Earth’s land is covered by Asia.
The Asian continent also represents 60% of the world’s total population.
The largest stalagmite in the world is almost 220 feet tall and is found in the Cuevo San Martin Infierno area of Cuba.
Our planet exhibits uneven gravity due to the uneven distribution of its mass.
70% of the Earth’s surface is covered in water.
The Earth has an approximate weight of 5.972 × 10^24 kilograms.
The Earth’s mantle consists of 21.5% Silicon, 44.8% Oxygen and 22.8% of Magnesium at an elemental level.
It also contains traces of Aluminum, Calcium, Iron, Sodium, and Potassium.
Alaska had the largest earthquake in the U.S. at a magnitude of 9.2 on the Richter scale.
The Earth is the only planet in the solar system with water in all 3 of its forms (liquid, solid, and gas).
Lightning strikes the Earth more than 100 times per second.
The Earth’s crust consists of 30% Oxygen, 32% Iron, 15% Silicon, 3% Sulphur, 14% Magnesium, and 2% Nickel.
The other 4% is made up of traces of Aluminum, Calcium, and various other miscellaneous elements.
So that essentially brings our list to an end. Hope you had a nice read.
