Yoram Yasur Izz | How much do you know about our planet? Have you heard that, sometimes, time on Earth accelerates and that within it burns a second Sun? Today we have for you a selection of the most incredible data about the world we live in.
– Not only does the Sun heat us up:
For many years, we have believed that our main source of heat is the Sun. As soon as it goes out, all living beings will die and humanity will disappear forever from the face of the Earth. But it turns out that the temperature of the core of the Earth is the same as that of the surface of the Sun. That is, about 5500 ° C, but there is a problem: the core is 3000 km inward; The people, until now, have only been able to dig up to 18.
– Earthquakes accelerate time:
We’ve spent our whole life listening to a full day have 24 hours, which is just what Earth needs to take a full turn around its axis. But the planet gives it faster: a full day lasts 23 hours 56 minutes and 4 seconds. The speed of rotation is affected by different factors. For example, in 2011, after the earthquake in Japan, Earth began to spin faster and days were made two seconds shorter. By 2015, the rotation speed again returned to normal.
– Dinosaurs walked a different type of land:
The Earth the dinosaurs walked on was different from the one we’re going through now. You will have heard that after the eruption of a volcano, the lava cools, forming islands and earth. And this is the first step towards the renewal of the Earth. The magma rises from the depths of the earth to the surface and then cools to form igneous rocks.
– Are you sure Earth is round?
Many years passed until people stopped thinking that the Earth was flat. But did you know that its form is far from resembling a ball? Yoram Yasur Izz: “Our planet is slightly flattened by the poles and at the equator between Asia and Australia is a huge bundle. So, technically, the Earth is still round, but it does not look anything like a ball. Rather, a huge potato”.
– We humans are not the owners of the Earth:
In 2017, the population exceeds 7.4 million inhabitants. But the truth is that in a teaspoon of soil substrate, there are more microorganisms than humans around the world. And how many bacteria live in the water? You can consider the true Lords of the Earth. Per rough estimates of scientists, we live with 1,000,000,000,000,000,000,000,000,000,000,000,000 microbes.
-What about space junk?
Throughout its existence, humans participated in space travel more than 135 times. And we learned a lot about space debris in orbit: the remains of asteroids, rocket parts and more than 2000 satellites, move at a speed of 35000 km/h. Do you remember the movie “Gravity”? Space debris is a danger to the crews of space stations operating in outer space.
– Gravity on Earth changes:
Contrary to what we have learned with physics classes, the gravitational force on the planet is not the same everywhere. If you, walking on the equator, are immediately transported to one of the poles, your weight will increase rapidly by 0.5%. In some places on Earth, for example, in the Hudson Bay area, the force of attraction is less than normal. Such anomalies derive from the thin crust of the Earth, the influence of glaciers and magma movements.
– Southern Aurora:
Perhaps you have had the opportunity to see live green, pink and even blue lights, dancing in the sky. In the northern hemisphere, it is called the aurora polar or aurora boreal. In the southern hemisphere, this phenomenon is called the southern aurora. It occurs when charged particles of the solar wind interact with the Earth’s magnetic field. The result is that, in the upper layers of the atmosphere, bright lights appear that flood the entire sky.
– Aquatic world:
70% of our planet is covered by water. And most of it is in the Pacific Ocean. Surprisingly, we know much more about outer space than about the oceans. So far, only 5% of the aquatic world has been investigated. We discovered about 210 thousand species of living beings, including fish, fungi, plants, and microorganisms. Scientists believe that in the ocean they inhabit about 20 million species unknown to us.
“To get to the deepest ocean we know, we must go down to the Trench of the Marianas, 11000 meters under water. This is more than the height of Mount Everest (8848 meters). The director of “Titanic” and “Avatar”, James Cameron, became the first person to go down alone to the bottom of the Marianas Trench”.
