We live on a strange planet . In asolar systemof fiery , poisonous hellscapes , icy slush balls and ballooning orbs of gun , Earthis the only satellite teeming with sentient , atomic number 8 - breathing sprightliness - forms . It is also the only world in the solar system have it away to be slowly but steadily wrick itself inside out throughplate tectonics , as the surface freshness of the major planet dive late into the mantle .
But Earth ’s foreignness hold up right smart , room deeper than that . From its oddball wobble to its wandering magnetic bailiwick , here are 10 way of life Earth revealed its bizarreness in 2019 .

Humans are messing up its wobble
Our satellite does n’t just orbit the sunshine and spin on its axis;it also wobbles like a topas it spins . That wobble has been shift , and now we cognise why : It ’s our defect . The planet ’s twisting axis has move a humongous 34 feet ( 10.5 meters ) , and two - thirds of that can be attribute to human - causedglobal warmingsince 1899 . As glaciers ( mostly in Greenland ) thawing and sea grade rise , the lighter , ice - free Continent arise as well and the major planet ’s great deal gets redistribute . That , in good turn , alters how the populace wobbles . Of course , humans are n’t the solitary crusade of this wandering wobble ; the dull butter churn of the crust into the pallium is responsible for one - third of the variety .
Its magnetic field keeps wandering
Earth ’s wayward magnetic field just ca n’t seem to rest put . Theplanet ’s prime meridian keeps wanderingas magnetic north move ever onward , move from its erstwhile home over the Canadian Arctic toward Siberia . And the field is n’t exactly moving slowly ; it has been steady marching at a tread of about 34 miles ( 55 kilometre ) per year over the last 20 years .
Earth ’s magnetic fieldis father by the mysterious churning of the major planet ’s atomic number 26 core , and for some reason , the subject field has been weakening in recent class . As a result , magnetic Union is on the move .

Set your Global Positioning System to 86.54 degrees north latitude and 170.88 degree east longitude , smack splash in the Arctic Ocean , according to the National Centers for Environmental Information , which released a example of the magnetized discipline on Dec. 10 .
Earth formed this massive geode
Proving that Earth has a flare for the striking , the satellite decided to make amassive room of pure lechatelierite , just because . The proficient term for this glitter excess is a geode , and it forms when weewee seeps into vacuous rock , allowing pee and mineral in the rock to chemically respond and constitute crystals within the tilt ’s interior .
This special example , known as the Pulpí geode , is the world ’s largest , and it can be attain only by fall into an abandon mine in Spain .
The icy , unmortgaged lance of rock are composed of gypsum crystals , mold through the chemical response between calcium sulphate and water over aeon . But how did the creation ’s largest geode arise ? This twelvemonth , scientists discovered that the geological wonder imprint at least 60,000 years ago and that the raw material , the calcium sulphate , that make up the geode enter the part when theMediterranean Sea sea drain like a bathtub , roughly 5.5 million years ago . The watch crystal themselves , however , did n’t start forming until 2 million years ago at the earliest , the work found .
It crafted this diamond-in-a-diamond
intelligibly , Earth loves its bling bling . instance in point : this baseball diamond - in - a - diamond . Not content to produce ordinary gemstones , our planet create this Russian nesting doll of mineral . Thediamond - within - a - diamond was plant before this yearin a mine in Yakutia , Russia .
But how did this ultrarare two-fold adamant shape ? It ’s likely that the lilliputian diamond form first and the larger one solidify around it later on , according to the mining company that found the stone . The first diamond could have become coated in a polycrystalline diamond substance , a grit that ’s not quite the same , structurally , as the fully imprint crystal . The outer diamond in all probability then began forming around that , and then the curtain squeezed and stir up the newly form gemstone until the diamond gumption dissolved . That depart the midget diamond inside the larger rhombus eggshell .
A never-before-found mineral was discovered
Another ball field , this one unveil in South Africa , also revealed a hidden surprisal : a never - before - found mineral . The dark unripened mineral was discovered at the volcanic website known as as the Koffiefontein pipe , where saturnine igneous rocks sparkle with hide diamonds . The inventor name the mineral goldschmidtite , after famed geologist Victor Moritz Goldschmidt .
But just where did this metric grain of goldschmidtite number from , and what does it reveal about our weirdo planet ? It turns out , the baseball field formed in Earth ’s mantle , the molten middle stratum . What ’s so unusual is the newly discovered mineral ’s composition : The sway is full ofniobiumand therare - Earth elementslanthanumandcerium . That mean something unusual had to pass off to bring these rarefied elements together , as the drapery is mostly composed of more coarse elements like magnesium and iron .
Earth showed off this freaky sunset
Earth ’s weirdness was on full presentation this July when a North Carolina house physician snapped a photo of thisgorgeous rent sundown . Though it looks like a inadequate Photoshop line of work , the moving-picture show is veridical . The unearthly split - sieve effect was because of a swarm baby-sit low on the horizon on the left - manus side . The set Dominicus hit the swarm , which shed a darkness and prevented the sunshine ’s light from reaching the diminished clouds below their big counterpart . On the right-hand - hired hand side , no such cloud bar the fiery light of the sundown , hence its more intense hue .
A lost continent is hiding under Europe
We misplace our keys ; the planet misplaces its continent . It turns out there’san full continent , known as Greater Adria , eat up beneath Europe . The ancient continent separate off from the supercontinent have intercourse asGondwana , which was made up of what is now Africa , Antarctica , South America , Australia and other major landmasses . And this year , researchers created the most precise Reconstruction Period yet of this lost continent , by piecing together ancient rock from Greater Adria that are still scattered across modern Europe .
Even during its efflorescence , Greater Adria would n’t have been completely above pee , but rather would have been a string of islands , researchers said . Adria ’s dying had start by about 100 million to 120 million age ago , when the now - recede continent crashed into Europe and commence dive below it . Some of Greater Adria was dispute off and crumpled in the process , creating the Alps .
A volcano erupted without warning
earthly concern can be dangerously unpredictable . That was the case on Dec. 9 , when theWhite Island volcanoin New Zealand erupted , ultimately kill 17 people . The volcano present piddling warning that it was rumbling before the deadly explosion .
But why was the bang so hard to auspicate ? According to GeoNet , the country ’s geological hazard - monitor system , the eruption was " impetuous and shortly - lived . " Thevolcano is prostrate to such irregular eruptionsbecause its shallow magma chamber heats the surround rocks , trapping superheated , pressurized water in their pores . Myriad tiny shift , such as changes in nearby lake level or small earthquakes , can unloose the press on this ensnare H2O , of a sudden tipping the organisation toward a phreatic , or steam , eruption . That steam quickly expands in volume , shattering rock and sending " hurricane " of plastered ash tree into the air .
Earth ruptured in weird ways
This summertime , the biggest quakes to rattle Southern California in decennium bust the ground in weird room . On July 4 , a order of magnitude 6.4 temblor shook Ridgecrest , a distant town in the outside Mojave Desert . Just a day afterwards , a order of magnitude 7.1 quake rip the ground 6.8 miles ( 11 km ) away from that berth .
Theearthquakesjangled a monolithic system of small , parallel and vertical break that look a bit like a " hanging shoe organizer , " Susanne Jänecke , a geoscientist at Utah State University , differentiate Live Science at the meter .
And theway those faults tear was very unusual . The fracture in the two temblor were vertical to one another , and until this seism , geologist used to consider such vertical break rarified . The July 4 temblor seemed to rupture the fault organisation in a complicated , messy direction , geologist said .
Together , the quakes hint that California ’s seismic action may be moving aside from the more well - knownSan Andreas faultto the more inland , eastern California shear zone , experts tell Live Science .
A massive, quiet fault in California slipped
In October , a field confirmed that the twin July quakes in Southern California had led to something more forbidding .
The earthquake caused slipping on the Garlock error , a so - called " tranquil " fault at the Mojave ’s boundarythat had not budge in 500 twelvemonth . The Garlock fault is capable of acquire a order of magnitude 7.8 temblor .
Even more disconcerting , the two quakes revealed that faults can " connect up " in a web to spread potent quake . Previously , seismologist believed that slippage usually occurred on only a single fracture and that the maximal possible seism magnitude was determined by the distance of that slip boundary .
The fact that fault can link up produce it much more challenging to prognosticate all possible quakes , seismologists say .
" It becomes an almost intractable problem to construct every possible scenario of these fault failing together — peculiarly when you weigh that the shift that tear during the Ridgecrest sequence were unmapped in the first place , " Zachary Ross , author of the study , and an assistant professor of geophysics at Caltech , said in a program line .
