Earth is a mysterious planet, there are so many things about it that we don’t know. Our home blue planet has so much to offer and its secrets are still waiting to be uncovered. From the weirdest natural wonders to the most unusual facts about Earth, there are many things that you might not know about our planet. We all know that Earth is home to humans and a variety of animals and plants, but did you know that it has some strange properties? Did you think about how many underground tunnels exist on this planet? Even if you think you know everything about Earth, we assure you that after reading this article your knowledge will grow significantly. You will be amazed by these unknown facts about our home planet, but before moving further let us tell you something more.
Facts about the Earth’s Atmosphere
The atmosphere is a vital part of our planet, but do you know which parts are included in it? The atmosphere consists of Nitrogen (78%), Oxygen (21%), Argon, CO2, and trace elements. If we talk about its thickness, it varies from 0 Km at the Earth’s surface to up to 100 Km in the upper regions of the atmosphere. The atmosphere is an ever-changing environment, which is affected by a number of different factors such as Solar energy, Wind, and Water. All this makes the atmosphere a complex and interesting structure. It is responsible for regulating temperature and pressure on Earth, as well as blocking harmful radiation from space.
The Mystery of Earth’s Core
The inner core of Earth is thought to be solid iron, however, what is the outer core? The core is considered to be the hottest part of the planet and scientists are still not certain how the temperatures are maintained at the level they are. The core is surrounded by the mantle, which is a hot and semi-liquid layer. The core of the Earth is made of iron and nickel, which are very dense metals. It is believed that the temperature of the core exceeds 4000 degrees Celsius. Scientists believe that the core of the Earth is responsible for the magnetic field of this planet. The outer core of Earth is thought to be liquid because of the extreme pressure, which is found in the mantle.
10 Strange Properties of Earth
- Earth is larger than the Sun: You might have heard that the Sun is the largest object in our Solar System, but what about the Earth? The diameter of the Earth is 12 times larger than the diameter of the Sun. - Earth is very old: According to scientists, the Earth is approximately 4.5 billion years old, which makes it the oldest planet in our Solar System. - Earth has a definite shape: For most people, the Earth is considered to be a perfect sphere, but it is not true. The Earth is a little bit wider around the equator, which makes it a geoid. - The core of the Earth is solid: As we have already mentioned, the core of the Earth is made of iron and nickel, which are two extremely dense metals. - Earth has a very strong magnetic field: The fact that the magnetic field of the Earth is so strong is one of the most interesting properties of this planet. - Earth is not a single piece: The surface of the Earth is divided into a large number of plates and most of them are moving. - Earth is almost completely covered with water: Most people believe that the Earth is mostly land, but this is not true. Only about three percent of the planet’s surface is dry land. - Earth has a very thick atmosphere: Scientists believe that the thickness of the atmosphere of the Earth is approximately five times the thickness of the crust. - Earth has weather: The fact that the Earth has weather and seasons is one of the most interesting properties of this planet.
5 Shocking Truths about our Blue Planet
- Earth is full of tunnels: Scientists believe that the number of underground tunnels on the Earth is significantly higher than the amount of people on this planet. - There is more water on the Earth’s surface than there is land: The oceans cover almost three-quarters of the surface of the Earth, which means that there is more water on this planet than there is dry land. - There are more bacteria living on Earth than there are people: There are more than five million species of bacteria on the Earth, which means that there are approximately five million species more than the number of people living on this planet. - Earth’s core is slowly cooling: The core of the Earth is slowly cooling, which means that one day it will become solid. This process, however, is very slow, so don’t expect it to happen in your lifetime. - Earth has an expiration date: Just like humans, the Earth is also dying and one day it will come to an end. Scientists believe that the Earth will live for another 1.75 billion years and after that it will die.
7 Shocking Things you didn't know about Earth
- Earth is losing its atmosphere: The fact that the Earth loses some of its atmosphere every year is not surprising, but what is surprising is the rate at which this process is happening. The rate of loss of Earth’s atmosphere has been increasing over the past decades and it is very alarming. - Humans are making the atmosphere thicker: The carbon dioxide in the atmosphere of the Earth is increasing every year and it is making the atmosphere thicker. Some scientists believe that this is the main cause of climate change. - The Earth is growing: Scientists are very surprised to discover that the Earth is actually growing, which means that its mass is increasing. We don’t know the exact reason why this is happening, but it is certainly very interesting. - Gravity on Mars is less than on Earth: The gravity on the planet Mars is around 37 percent of the gravity on Earth. This means that you would weigh less on this planet and you would be able to jump higher. - The Earth’s core is contracting: Just like the surface of the Earth, the core of this planet is also contracting. The only difference is that the core of the Earth is doing this very slowly. - Earth’s magnetic field is weakening: Scientists have discovered that the magnetic field of the Earth is weakening at a rapid rate, which means that it is going to cease to exist one day.
Conclusion
The Earth is a beautiful planet, but it is also delicate in a way that if certain changes take place, they could cause irreparable damage to the planet and result in the death of both humans and other lifeforms. This article has provided you with all the exciting facts about our Earth. We hope that it has inspired you to learn more about this planet, its history, its inhabitants, and the future of this blue planet. Now that you know more about Earth, you can be prepared for what is to come and appreciate it even more.
