Our universe is the most amazing and mysterious creation, and the Earth is just a tiny part of this huge mystery.
1. Volcanic mountain ranges encircle the Earth
The mid-ocean ridges are a huge system of volcanoes formed as a result of eruptions of basalt lava between tectonic plates of the Earth. Eruptions have created the “youngest” earth crust in the lithosphere.The mid-oceanic ridge (60 thousand km) actually encircles the planet and causes some interesting natural phenomena.For example, when icy ocean water seeps into cracks in volcanic rock, it heats up to almost 400 Degrees and flies into the air with fountains of gray-black color, which are called “black smokers.” By the way, the main volcanic activity of the planet passes precisely along this ridge.
2. Fire adores cold, ice and permafrost
Strong winds and dryness of Antarctica are the cause of rapidly spreading fires. A fire in Antarctica put out is problematic, because the water instantly freezes. The stations are far from each other, and it takes a long time to wait for help, because people pay much attention to fire safety. The reason is static electricity. Low humidity and strong winds lead to its occurrence, and only one static spark can ignite fumes of steam and cause a fire. In addition, there is also Mount Erebus in Antarctica, an underwater active volcano with a huge lake of hot lava, ready to burst out at any moment.
3. Earthquakes are not uncommon
Earthquakes on Earth occur approximately 500 thousand times a year, people feel only a fifth of them .The insignificant and inconspicuous earthquakes Up to 8 thousand times a day Earthquakes that can be felt happen 55 thousand times a year Medium and strong earthquakes (5.0-8.9 points) lead to destruction (about thousand times a year) .The most powerful earthquakes are a rare phenomenon, they Occur once in 20 years (9.0-9.9 on Richter) .In the event of an earthquake of this magnitude in 1556 in China has killed more than 800 thousand people.The earthquake above 10 points has not been recorded to this day.
4. The core of the Earth is as hot as the Sun
There are three layers on the Earth.The heated core is in the molten state from the outside, but it is dense in the center. Layer is a mantle composed of hard rocks (84% of the volume of the Earth) .The uppermost layer is a very thin crust, where there is life.The core is the most inaccessible and poorly studied, the thickness of the outer core is 2300 km, the temperature is more than 3900 degrees Celsius, contains It is mainly iron and nickel.The inner core is a ball 1207 km thick, which is an alloy of yell This ball supports the protective magnetic field of the planet, and its temperature is 6100 degrees Celsius, which is comparable to the temperature of the Sun.
5. Large weight can lead to deformation of the Earth’s surface
In 2002, the giant shelf ice shelf of Antarctica” Larsen B “collapsed in the Weddell Sea. Its area was about 3250 square meters. Km, thickness – 220 m, and weight – 720 billion tons. Too much weight to disappear so suddenly. The shift was powerful enough to cause changes in underground mountain and lava flows, as well as “disturb” nearby volcanoes. If the entire ice of Antarctica melts, then the sea level will rise by 60 m. By the way, the surface of Atlantis is crushed by thick ice layers, and they are so heavy that most of the land on the continent is now below sea level.
6. Nearly 95% of the ocean is still unknown
Although the water covers 71% of the Earth’s surface, we have investigated no more than 5% .The sunlight penetrates only At 275 m, the rest of the dark abyss remains unknown, there are millions of species of living creatures in it, but many of them can die out before we can get to them, as the acidity of the ocean has increased by 30%, and it destroys coral reefs and destroys some And mankind annually throws 180 million tons of toxic substances into the world’s oceans The Mariana Trench near Guam is the deepest part of the ocean (10,900 m), just imagine how many discoveries are still ahead.
7. The level of gravity is a variable quantity
Do you think that gravity is the same everywhere? The answer is incorrect. For example, in Hudson Bay (Canada) the weakest level of gravity on Earth. The difference is insignificant and imperceptible, but modern technologies fix it. The most common theory leads to the era of the Ice Age. When the ice shield melted, it affected the gravitational field, albeit to an insignificant degree. This ice cover occupied most of Canada and part of North America. The same thing happened and happens at the South Pole. Melting ice in recent years has caused there explicit changes in gravity.
8. Approaching Pangea Ultima
Pangea is a single continent that unites all seven modern continents into a single whole that existed 250 million years ago. After another 250 million years, most likely, the time of Pangea Ultima will come, and it will be very different from the ancient Pangea. Scientists predict that California will unite with Alaska. Most of the Mediterranean Sea is in fact part of the African tectonic plate, therefore Africa will join Europe, creating a giant mountain range. Look at the Alps to understand the potential consequences of tectonic plate collisions. The formation of a single continent on Earth occurs cyclically, every 500-700 million years, and now we are in the middle of this cycle.
9. North and South poles change places
This exchange of seats is a natural cycle, which has happened countless times in the past, and this will happen in the future. Volcanic rocks indicate that in the past, the exchange of places occurred 780 thousand years ago, the magnetic activity around our planet shows that soon this cycle will begin again.The magnetic field around the Earth protects us from radiation, but it changes faster than predicted, weakening in some Areas and strengthening in others. The field depends on the motion of the outer core of the Earth: a weak movement causes a weakening of the magnetic field, a rapid movement intensifies it.Current activity may mean that the process is currently already running, but it will not be over in hundreds of thousands of years.
10 The earth, in fact, is very tiny
The Earth is smaller than the Sun, and it is strikingly smaller. On the surface of the Sun can accommodate 109 Lands, but inside it will accommodate approximately 13 million of our planets, given the net volume without empty space. Even if we take into account only the spherical shape, then within the Sun 960 thousand of Lands will fit. In addition, the Sun is 333 thousand times heavier than the Earth. Now imagine the star of Betelgeuse, which is 500 times larger than the Sun. As you can see, our planet is just a tiny speck in the universe.
