One quadrillion tons of diamonds can be found 100 miles below the earth’s surface. But how do we know when the longest we have walked is 7 miles down? Printout of the video: A quarter ton of diamonds is said to be hidden 100 miles below the Earth’s surface. But how can we know that there are diamonds at the bottom if we have never been so low? We should start by asking how we know what lies hundreds of kilometers below the Earth’s surface. We generally know of earthquakes and nuclear explosions caused by seismic waves created by the earth that shake or vibrate in response to applied forces such as earthquakes or nuclear explosions. When I do this, it’s similar to how Jello reacts in a court.

Primary waves, secondary waves and surface waves are the three main types of seismic waves. The speed and direction at which P- and S-waves travel through the Earth tell a great deal about the various materials hundreds or thousands of kilometers below our feet.

The fastest waves are P-waves, which move about four miles per second. As a result, seismometers detect them first. P-waves move like an empty worm, contracting and expanding as they move. They also move faster through denser, stiffer materials such as stone and metal, but slower in liquids.

The scientists found that after p-waves reached a certain depth, they slowed down and deviated significantly while traveling to the other side of our globe, resulting in the “shadow region of the P-wave” – ​​on the opposite side of the Earth . An area where no parking waves can reach.

Later, geophysicist Inge Lehmann suggested that a floating area existed between the two rock layers we now refer to as the Earth’s mantle and inner core. The outer core of the earth is a liquid layer.

S-waves flow in a way that suggests a floating outer core. They move in an up-and-down or side-to-side action and change shape depending on the material they pass through. They are about half the speed of P-waves and move in an up-and-down or side-by-side motion, changing shape depending on the material they pass through. S-waves, like P-waves, travel at different speeds through different solids. And the course depends entirely on how … Brinkwire’s summary of the latest news.
