People have wondered about if there's another world underneath the earth all through history. It existed even though ancient Greeks believed it, although their beliefs were more mythological that literal. Modern science however maintains that our planet's layers are made up of a dense, hot core and liquid magnesium. One of the most popular theories from the 17th century was that the planet is hollow and that another world exists below it.
Plate tectonics
Earth is currently undergoing a continuous process of plate tectonics. This is responsible for the formations of mountains and oceans as well as the incandescent volcanic eruptions we see today. But, eventually, plate tectonics, which is cooling enough to cause the entire planetwide conveyor belt to come to an abrupt halt, will stop the process that shapes our planet.
Habitable zones
Earth is one example of a planet having a habitable area under its surface. The solar luminosity and solar irradiance determine the outer and inner limits of the zone. The solar constant has a value equal to 0.53. This is equivalent in astronomical units of 1.37.
FAQ
Which is the most mysterious spot on Earth?
Antarctica is home to the most mysterious and remote place on Earth.
We find this place so fascinating. Because it's unlike any other place in the world.
It is very remote and isolated. This site has more to it than meets your eye.
These wild animals are also found in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
Antarctica is named for no one. Others believe it means "land with ice". Others believe it comes from Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. One of the twins was said to have been born in winter. Thus, the term antarctic.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would mean land turned away from the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is also the lowest, windiest continent, driest, and highest. It is too cold to support trees, plants, and animals.
This frozen wasteland is still alive.
It is home to approximately 90 percent of all life on Earth. You can find approximately half the world's species of animal and plant plants here.
What makes Antarctica so special? Here, water is frozen into ice rather than vaporizing into the air.
This creates large masses of ice that float above the ground.
These glaciers are responsible for covering 80% of the continent. They're getting bigger every year.
The Antarctic ice sheet has grown 60ft since 1960.
The sea level could rise to 200 feet if the melting continues. This could lead to widespread flooding.
But not everyone thinks this is bad news. 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 for breaking down toxins and storing vitamins and minerals. It helps to regulate blood pressure and keep our bodies temperature stable.
What number of times have you heard someone say that they feel sluggish or heavy? These symptoms could indicate liver problems.
You may notice symptoms such as dark urine, yellowing skin and fatigue. These aren’t the only warning signs. If you are experiencing any of these signs, it is important to consult your doctor right away.
The liver, an essential organ, is vital. It is essential for detoxification and metabolism as well as reproduction.
-
The average adult human liver weighs approximately 1,400 grams.
-
At birth, the liver of a baby can be half as big as an adult's. It grows to be about four times bigger by age three than an infant's.
-
The liver can be found just below the rib cage, on the left side.
-
There are 16 major liver lobes. However there are many smaller, more intimate lobules.
-
The liver is home to approximately 10 million red blood cell units.
Did you know that there are approximately 1.6 billion metric tons of trash produced every day in the world?
The United Nations estimates that the average person generates more than 2.5 pounds of waste each day. This adds up to over 25 million pounds of garbage annually!
Many of this trash ends in landfill dumps, or incinerators. But what happens if those dumpsters are full? Where does all that rubbish go?Well, most of it gets shipped out of the country. The rest is dumped abroad, where it pollutes other ecosystems. Now, we know the exact location of all this garbage. Mike Sexton is his full name. He runs a company called Waste Watchers.He spends his days watching the movements of trucks transporting trash across North America. Then he reports back to us about what happens next.
Sexton said he enjoys his job. "We've got a lot of fun," he told CNN. "We often see large rigs passing through our town and we will follow them. "Sexton started following truck drivers nearly 20 years ago.
"I just fell in love with it," he said.
His favorite story involved a driver who pulled off at an abandoned gas station near Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He drove down the road and saw this building. He backed up and entered the building. "There were 2 large containers that had been rolled off, and they were full of stuff. He took out everything and began to fill up the truck. "Then, he took everything out and started filling up the truck again. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was a complete mess. But it was cleaned out before he came. There wasn't any trash anywhere."
So why did this happen? This particular spot used to be a recycling center. People would drive there to recycle their trash. "They'd bring their household items and take them to this building," Sexton explained.And after they finished, they would leave the empty containers behind.
You might see this happen hundreds of times a day. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. And eventually, the owner decides to abandon the vehicle.
However, trash is not the only problem on our planet.
These tiny plastic particles make up the majority of the particles. Some end up in incinerators or landfills. Some are washed into rivers and oceans. Others end up with fish in their stomachs.
Experts warn that if there is no change, the world could soon be facing a food shortage. "If we keep going like we're going, we're not going to make it," one expert warned.But even though scientists agree that the world is headed toward disaster, most people don't seem worried.
How does your brain control the functions within your body?
The brain relays messages to other parts of the body to ensure their functionality. Everything in your body is controlled and managed by your brain. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Neurons communicate with each other by sending electrical signals called action potentials on axons. Each neuron has its own cell membrane around its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. Ion movement creates the electric charge that causes the neuron to fire.
Neurotransmitters, which are chemicals that release neurotransmitters when a neuron fires up, can be found in the space between the neurons and the next one. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. In turn, the second neuron also fires.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. An impulse travels along a synapse that connects the two neurons. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
Communication within the nervous system is possible thanks to neurotransmitters. They also coordinate activity between different brain parts.

- You spend about 10% of your time awake blinking (romper.com)
- The average human adult male heart rate is between 70 and 72 beats per minute, while the average for adult women is between 78 and 82 beats, which is significantly faster, according to 2014 published in the Journal of Clinical and Diagnostic Research. (romper.com)
- In fact, according to the American Academy of Ophthalmology, you make 15 to 30 gallons of tears each year, which is insane when you think about it. (romper.com)
- According to a 2018 study published in Free Radical Biology & Medicine, this is because blood pressure is regulated by our innate circadian rhythm and internal clock. (romper.com)
- A 2012 paper published in the Proceedings of the National Academy of Sciences reported that people blink about 15 to 20 times each minute, meaning, if you do the math, you spend about 10% of the time that you're awake blinking. (romper.com)

Hollywood scandals that shocked the globe
There is nothing more shocking than witnessing someone get famous for the wrong reasons. There's nothing more shocking than watching someone fall from grace.
The best thing about watching how an industry reacts when it makes mistakes is the best part. We've all heard stories of celebrities who used drugs and alcohol excessively. Some even died young because of it.
But, the worst part? When those stars openly discuss their issues and are ignored by everyone. We were there last week.
Heath Ledger, after a long and successful professional career, finally gave in to his demons. He succumbed after taking too many prescription medications. After a brief struggle with death, he died.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once regarded as one of the best actors today. His performance in Brokeback Mountain earned him two Academy Awards nominations.
Heath, in addition to acting, also wrote and directed films such as A Knight's Tale (Monster's Ball) and Iron Man (3).
Hollywood loved Heath. But he was too big for his boots. He began using drugs and drinking heavily. He ended up in rehab and became clean.
After he had gotten sober, he decided to make amends. He made a documentary called "Room 237," that chronicled the making and release of The Shining. The film was originally supposed to be released in this year's theaters, but it will not make its way into the cinemas until next year.
Heath tried unsuccessfully to get into Hollywood again, but nothing happened. In fact, he was actually twice arrested for drug-related charges.
We don't believe Heath should have been allowed to go back into the entertainment industry. It would have been nice for him to have received some assistance before things spiraled outof control.
We hope Heath’s story can be an example to other people who believe they can still have it all.
