People have always wondered whether there is another world below the earth. Even though some ancient Greeks believed it existed, their beliefs were more mythological rather than literal. However, modern science maintains that our planet is composed of an unbroken series of layers made up of dense hot core and liquid magma. 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's ongoing process of platetectonics is responsible in part for the formations today of mountains, oceans, as well as incandescent volcanic eruptions. The planetwide conveyor belt that links plates tectonics to the surface will eventually stop rotating at some point in time. This will end the ongoing process of reshaping the Earth.
Habitable zones
Earth is one example a planet which has a habitable subsurface zone. The solar irradiance, and the planetary luminosity determine the zones' inner and outer limits. The solar constant is 0.53 times the upper limit. This equals 1.37 astronomical units.
FAQ
Why do actors get blacklisted?
As an actor, rejection is much more common than for writers. As an actor, it's likely that you will be rejected a lot. It doesn't matter if you get rejected a lot because eventually you'll meet someone you love.

However, once you have been cast, it is possible to face criticism. Many people will tell you you look horrible or that you shouldn't be wearing make-up. If you're lucky, you won't even hear negative comments.
Sometimes, your performance as a fictional character can be ridiculed. Maybe you play a gay man, and everyone thinks you're straight. Maybe you are a woman who is tough but cries often.
Sometimes, they ask you to change your voice. Sometimes, they want you to sound more like a man or a woman. They want you to sound better most of the time.

What is the most mysterious location on Earth?
Antarctica is the most mysterious continent on Earth.
Why do we find this place so intriguing? Because it's unlike any other place in the world.
It is isolated, remote, and very hard to visit. However, there's more to this location than meets the eye.
This natural wonder is also home to some of the strangest wildlife species.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Others believe it means "land with 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 legend, one twin was born in winter. The term antarctic is derived from this.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would be land turned away form the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the continent with the lowest, windiest and highest temperatures. There are no trees, plants, or animals here because it is too cold.
Yet, this frozen wasteland is alive.
Here, 90 percent live of all species of living things. About 50% of the world's plant and animal species can be found here.
What is Antarctica? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large masses to form of ice which float high above the ground.
These glaciers cover more than 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 goes on, the sea level may rise by as much as 200 feet. This could lead worldwide flooding.
However, not all scientists believe this to be bad news. Some scientists claim that global warming could be good for us. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils and bodies.
Others warn that this theory sounds like something out of a science-fiction movie.
How does your brain control your body's functions?
The brain sends messages to other organs and muscles to ensure they work together. The brain controls everything that happens in your body. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Every neuron has an outer cell membrane that surrounds its nucleus. The cell membrane houses channels that allow ions, such as potassium and sodium, to enter and exit the cells. Ion movement creates the electric charge that causes the neuron to fire.
When a neuron fires, chemicals called neurotransmitters are released into the space between the neuron and the next neuron. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. As a result, the second neuron fires too.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. An impulse travels along a synaptic link between the two neuron. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
For communication within the nervous systems, neurotransmitters are essential. They also coordinate activity between different brain parts.
Ever wonder how much trash gets produced each day around the world?
The United Nations states that an average person produces more than 2.5 pounds of waste per day. That's over 25 billion pounds of garbage each year!
Most of this trash ends up in landfill dumps or incinerators.But what happens when those dumpsters get full? All that trash ends up being shipped out of country. The trash is then sent out of the country and dumped in countries where it pollutes ecosystems. But, one man has now discovered exactly where this rubbish goes. Mike Sexton is his name. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He reports back to us about the next steps.
Sexton claims he is very satisfied with his job. CNN interviewed Sexton and said that he has a lot of fun. "We see these big trucks coming through town, so we'll keep following them. "Sexton started following truck driver almost 20 years back.
He said, "I fell in love with it."
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton remembered, "The man was looking for somewhere to put the load." "He drove down the road to see this building. He pulled over and went in. "There were two huge roll-off containers there filled with stuff. The man took all the stuff out and filled up his truck with more. "Then, he took everything out and started filling up the truck again. There were many old tires, furniture, rags and mattresses. "It was a complete mess. But it had been cleared out before he arrived. There wasn’t trash everywhere."
This begs the question: Why? It is because the location used to belong to a recycling centre. People who found out about this facility would drive to it to recycle their trash. Sexton explained that people would bring home their household items, and then take them to the building. After they were done, they would dispose of the empty containers.
This could happen hundreds of time per week. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. The owner eventually abandons 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 end up in rivers and oceans, while others end up in fish's 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.
