If you ever lived on Earth, there are probably a number of interesting facts that you remember. Some of these facts can be the age, the nearest planet, or the highest point.
70 percent of Earth's surface is covered in vast oceans. This isn't just a coincidence, as it's an essential part of the Earth's makeup and one that is critical for life on Earth.
Earth is composed of a dense core made from iron and nickel that extends into the mantle, crust, and outer layer. The outer layer of mantle has a dense, rocky surface while the inner layer is soft and thin.
The Earth's oceans can hold an enormous amount of water despite its dense mantle and core. This is only one planet in the solar system to do so!
The Earth is also the only one with a powerful magnetic field that protects it against the sun's harmful radiation. This magnetic field is caused both by the nickel and iron core of Earth, as well as its rapid rotation.
Earth has a unique feature: it's one of only 3 planets with an oxygen-rich atmosphere. Oxygen is essential for plant life. It is also the only planet with a layer that absorbs the majority of harmful UV rays from the Sun.
The Age of the Earth
Scientists estimate that the Earth is 4.5 billion years older than any other planet in our solar-system. Scientists determine this by dating rocks and meteorites on Earth which formed at the time the solar system began to form.
Scientists can use a variety of methods to determine the age of rocks or sediments, such as radioactive decay based on four isotopes derived from nitrogen and methane. They also use the rock cycle and the processes of plate tectonics to find out the age of rocks.
On the planet, a lot of sediment and rock is recycled. This means that they are broken down and pumped again up to the top. This process is called plate tectonics and it helps shape our planet's terrain.
The most dominant features on the Earth are mountains, valleys. Canyons, plains and river. Some of these features are natural and some are artificial.
Mount Everest stands at 29,028 ft above sea-level. It is also the highest point on the planet.
The Earth is flattened into an oblate-spheroid shape. This is due to the fact that as it spins on its axis, the equator bulges and the poles widen.
This is due to the Earth's rotation and the Moon's gravitational pull. When the bulge is in full swing, it causes the sea level to rise and drop.
FAQ
What is the most secretive place in the world, and why?
The answer to that question may shock you. It could even make you uncomfortable, because it challenges how reality is perceived and lived. But there is a reason that this place exists. It isn't what you would expect.
The City of God was its name by the ancient Greeks. According to the Bible, it was called the City of Destruction.
It is called Kashi (Kashmir in India). It's also known as Novgorod in Russia.
It is known as The Town That Disappeared in America.
A small town in western New York State, with a population of 1,200, vanished without a trace. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
This little community vanished and no trace remains to indicate where or when it disappeared. Some claim the earth swallowed it. Others believe it was destroyed by a meteorite. Others claim it was taken away by aliens.
The people of this once-thriving community, however, are positive that the town won't disappear forever. They had just moved from one town to the other.
There is even a website dedicated to tracking the disappearance of the lost city of Zugspitz.
So, where exactly did this town go? It's in Switzerland.
Zugspitze is located on the border between Germany and Austria. The lake Lake Zugspitze is just beyond the mountain's summit.
It has always fascinated and astonished me to see how many towns have vanished but still exist. Why is it that some disappear while others live on? I decided to investigate.
I wanted to learn more about mysteriously disappearing towns. Is it possible for a place to vanish? How can one place become extinct?
It turned out that there are many theories about disappearing towns. One theory holds that a town disappears if all its buildings are demolished. Another theory states that the town simply moves to another location. A third theory states that the town didn't exist at all.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video looks into the history of those places and investigates their current status.
What are the darkest secrets of Hollywood?
Hollywood is full of secret societies. Many secret societies are cult-like and follow rigid rules. Others are just clubs for people with common interests.
But there are also more nefarious organizations that control much of the industry. Companies such as the MPAA, which determines film ratings, or the RIAA (Recording Industry Association of America), that set music licensing fees, are examples of these.
Numerous unions, guilds, and associations represent actors, writers, producers, editors, and other creative professionals. Most major movie studios and television networks are owned by large corporations which own these various organizations.
The point is that no matter how secretive any group may seem, someone somewhere knows exactly what they do. They shouldn't be fearful, however.
Instead, embrace them. Because they give us information that allows us to make better decisions.
They tell us what movies will likely succeed, what songs will be popular, and what books will best sell.
They allow us to make informed decisions about what we buy, watch and listen to.
We can trust our advisors and ignore advice that isn't in accord with our tastes.
Because we have chosen to ignore their power, they are even more powerful. They are the ultimate arbiters and judges of taste.
You are free to ignore their messages if that bothers you.
Let's now take a look into some lesser-known but very real Hollywood secret societies.
And see why they're so important.
Is there a more mysterious place than the Earth itself?
Antarctica is home to the most mysterious and remote place on Earth.
Why is this place so amazing? Because it's unlike any other place in the world.
It is remote, isolated, and extremely difficult to visit. But there is more to this site than meets the eye.
You'll also find the strangest species of wildlife in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some say it means "land on ice." Others believe it derives from Greek mythology.
Antarktis, the Greek name for the island on which Zeus' twin brothers were conceived, was used in ancient Greece. According to some legends, one of these twins was born in winter. Thus, the term antarctic.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would be land turned away form the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the driest, windiest of all continents. Because it is too frigid, there are no trees, animals, or plants.
This frozen wasteland is still alive.
Here, 90 percent live of all species of living things. You can find approximately half the world's species of animal and plant plants here.
What is Antarctica? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large amounts of ice to float above ground.
These glaciers are responsible for covering 80% of the continent. They continue to grow in size each year.
The Antarctic ice has grown 60 feet so far since 1960.
If the melting continues, the sea level will rise by up to 200 feet. This could lead to massive flooding across the globe.
This does not mean that everyone is wrong. Some scientists believe that global warming can be beneficial. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
What are 5 interesting facts about the liver?
The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It regulates blood pressure and maintains a stable body temperature.
Is it not often that we hear people say "I feel sluggish today" and "my head feels heavier?" These symptoms could indicate problems with your liver.
You may notice symptoms such as dark urine, yellowing skin and fatigue. These are not all the warning signs. If you are experiencing any of these signs, it is important to consult your doctor right away.
The liver is a vital organ. It plays a role in detoxification, digestion, metabolism, immunity, and reproduction.
