According tomedia reports, we live on a strange planet, the solar system hot and hot, full of toxic gas, as well as icy snowballs and expanding gas, and the Earth is the only solar system full of oxygen for life to breathe, and the only planet through plate tectonics slowly and steadily flipped “from the inside out”, Because the earth’s crustal surface extends to the mantle. Here are the top 10 strangeest things to discover on Earth in 2019:
1, humans are disrupting the Earth’s “normal swing”
As the Earth orbits the sun and rotates around its central axis, it swings like a gyro, and the earth’s wobble is constantly changing, and now scientists have solved the mystery — caused by human activity. Since 1899, the Earth’s axis of rotation has shifted by 10.5 meters, two-thirds of which can be attributed to global warming caused by human activity, and as glaciers melt and sea levels rise, lighter, ice-free continents will gradually rise and the Earth’s mass will be redistributed. This will change the earth’s wobble, and of course, humans are not the only cause of the Earth’s wobble, with the earth’s crust slowly stirring the mantle, causing a change in one-third of the mantle.
2. The earth’s magnetic field is in drift
The Earth’s magnetic field is so “wayward” that it doesnot seem to be constant, and the Earth’s early meridian has been drifting, moving northwards, moving from the Canadian Arctic to Siberia. The region is not moving slowly, and for the past 20 years it has been “moving at a constant speed” of 55 kilometres per year. The Earth’s magnetic field is caused by mysterious forces in the Earth’s iron core, which for some reason has been weakening in recent years, causing the geomagnetic north pole to move. Want to see the position of magnetic north? According to the magnetic field model data released by the National Environmental Information Center on December 10, gps was set at 86.54 degrees north latitude and 170.88 degrees east longitude, and the magnetic north is located right over the Arctic Ocean.
3, the earth formed a huge crystal hole
The gleaming crystals are beautiful, they are formed when water penetrates into hollow rocks, where water and minerals react to form crystal structures inside the rock. The Pulpi Crystal Cave is the world’s largest crystal cave, which can only be seen by elevator to Spain’s abandoned mines. These cold, clear, transparent rocks are made up of gypsum crystals, formed by the chemical reaction of calcium sulfate and water over thousands of years, but how did the Pulpo crystal cave form? In 2019, scientists discovered that the cave wonder sat about 60,000 years ago, about 5.5 million years ago, when the Mediterranean dried up like a bathtub, large amounts of calcium sulfate entered the region, and the earliest crystals began to form 2 million years ago.
4, “Diamond Set”
People love diamond jewelry, the mysterious earth is not enough to make ordinary gems, but also to make a Russian nesting diamond, earlier this year, people found a “diamond set” at a mine in Yakut, Russia. How did this super-rare diamond come about? According to the mining company that discovered the diamond, it is likely that the small diamond formed first, then the large diamond cured around the small diamond, the small diamond may be wrapped in a polycrystalline diamond substance, the material is structurally different from the completely formed crystal. The outer diamond is likely to form around it, after which the mantle is squeezed and heated to form a new diamond until the diamond particles dissolve, so that the small diamond particles are preserved inside the large diamond.
5, never seen before minerals
An undiscovered mineral, found in South Africa, was found in the Koffifontein Pipe, which glowed hidden in dark, flamboyant rock and named it after geologist Victor Moritz Goldschmidt. Goldschmidt Rock.” But where does this rock come from? It turns out that the rock is formed in the mantle, the melted middle layer, and the newly discovered mineral composition is unusual, filled with niobium and rare earth elements, niobium and niobium, which means that rare earth elements come together strange lying, because the mantle is mainly made up of more common elements, such as magnesium and iron.
6, split-screen sunset
In July 2019, a North Carolina resident captured a gorgeous split-screen sunset that many thought was a PS photo, but in fact it was a real photo, a bizarre split-screen effect caused by a cloud on the left-hand horizon, where the sun falls and the clouds cast shadows. The small clouds that keep the sun’s rays out of the clouds, on the right, do not have similar clouds to block out the hot light of the sunset, thus giving a split-screen, brilliant sunset view.
7. Hidden in Europe’s “Lost Continent”
The Earth’s continent is “misplaced”, originally hidden underground in Europe a whole continent, known as the “Greater Adria”, an ancient continent from the Gondwana supercontinent, which is now divided into Africa, Antarctica, South America, Australia and other major continental parts. In 2019, scientists will make the most accurate reconstruction of the lost Great Adria, piecing together the ancient rock regions of Greater Adria across modern Europe. Even in its heyday, the researchers point out, the Greater Adria continent will not be fully present, but is made up of a series of islands. The continent began to split 100-120 million years ago, when it began to dive, and in the process some continental mountains collided to form the present-day Alps.
8. Unaeundy volcanic eruptions
The danger of the earth is unpredictable, with a volcano on new Zealand’s Isle of Wight erupting on December 9th, killing 17 people, and the volcano barely rumbled before the deadly eruption. But why are volcanic eruptions so unpredictable? According to GeoNet, the national geological hazard monitoring system, the eruption was “intense and short-lived”. In fact, the Isle of Wight volcano is prone to unpredictable eruptions because its shallower magma pools heat the surrounding rocks and trap overheated, pressurized water in rock pores. Numerous small changes, such as changes in the water level of nearby lakes or small earthquakes, can release the pressure of water in the rock pores, causing them to suddenly form steam eruptions that expand rapidly to crush rocks and form “hurricanes in the water” to spew out the water.
9, strange earthquake
In the summer of 2019, southern California experienced the largest earthquake in decades, causing a fault zone on the ground, and on July 4th a 6.4-magnitude earthquake struck the remote town of Richcrest in the Mojave Desert, a day after a 7.1-magnitude earthquake struck 11km from the town of Richcrest. The quake formed a small, parallel and vertical fault system, and the faults were perpendicular to each other, after geologists thought the vertical fault was rare, and the earthquake appeared to destroy the fault system in a complex and chaotic way. Combined with these seismic events, California seismic activity could shift from the San Andreas fault to the more inland eastern California shear belt, experts said.
10, 500 years after silence California’s “quiet fault” began to slide
In October 2019, scientists showed that two earthquakes in Southern California in July caused more ominous events, resulting in the “Gallok Fault” sliding, a “quiet fault” at the edge of the Mojave Desert that has not moved in the past 500 years, and that the “Garlock Fault” slide can produce a 7.8-magnitude earthquake. More disturbingly, the two quakes showed that faults could be “connected” to form a network of powerful earthquakes, after seismologists believed that geological sliding occurred only on a fault, and that the magnitude of the magnitude was determined by the length of the sliding boundary. For now, seismologists say, faults can be interconnected, which can be more challenging to predict all possible seismic events.
