Top 5 weird occurrences which is unsolved on Planet Earth

1. SINKHOLE

sinkholes are a natural occurrence of our geological mantle. They can be man-made or in most cases brought on by the plain and organic process known as karst. Chemical dissolution of carbonate rocks, in general, they may vary in sizes from three feet up to 1,800 feet in diameter and depth. They are found throughout the world as a blight on Florida's real estate due to the state's honeycomb swampland or as tourist attractions in Mexico's Mayan Riviera called cenotes.

Over the last years, these chasms have been swelling in numbers in 2017b Florida saw a spike of over 32 sinkholes. A stark contrast to the eleven reported in 2016 but as a rule, these shallow holes are rather ubiquitous in the grand scheme of things. We'll all but one the Guatemala city sinkhole in 2010. Guatemala City Zona Dolls was developed with a cataclysmic disaster that ended up claiming over 15 lives not to mention.

An extra 300 more that had to be relocated the sinkhole of over 65 feet across and 300 feet deep ended up swallowing whole a three-story factory to this day. The exact cause of that particular sinkhole is theories are a dozen from the torrential rains of a tropical storm to sewer pipe leakage and even an inner curst volcanic eruption.

2. FAIRY CIRCLES 

Fairy circles Namibia in the arid grasslands of the Namib desert in coastal southern Africa lies inland over 2000 kilometers fraught with mystic and scientific irregularities like the welwitschia plant. A living fossil found only in that landscape one of this region's biggest and eeriest mysteries are the fables fairy circles over a million perfect round. Circular patches between 2 meters to 15 meters in diameter arranged in a geometric pattern across 2500 kilometers of land.

These disks of bare soil pockmark the region in an intricate array that almost seems man-made due to its precision adding to the mystery says geologist prem raft is the fact that no one knows for certain the cause of these otherworldly formations. Nonetheless, there really are no shortage of theories some plausible and others far-fetched hypotheses like radioactive soil and termites plant toxins or as local Bushmen are prone to believe they are the footprints of the gods.

3. THE DOOR TO HELL

The door to hell derweze Turkmenistan first identified by Soviet engineers in 1971. The door to hell is a collapsed underground gas crater dead set in the middle of the Karakorum desert about 160 miles north of Ashgabat the capital of Turkmenistan little is known about the gates of hell and what scraps remain in the official records are a bit sketchy.

In 1971 a cavern flourished out of nowhere right where the doors now stand according to geologists a Nottoli Bush. It was originally thought to be a substantial oil field the oil rig collapsed into the crater and a could of toxic methane gas started to spread over the countryside. The engineers had no other choice but to intentionally set it to fire to prevent a full-blown environmental disaster. Since the 226 foot wide and 98-foot deep pothole had been scorching the landscape. 

4. THE FROZEN METHANE BUBBLES

The frozen methane bubbles Canada they had been described by the press as ice encapsulated jellyfishes frozen over flying saucers and even ancient deep-frozen pizza yet in the essential words seem to fail the otherworldly attraction of Canada's frozen methane bubbles. Methane bubbles are generally found the higher northern latitude lakes in Alberta Canada the stunning and potentially fatal sites greenhouse gas not only warms the planet.

But it is incredibly flammable is still an unsolved mystery to science the gas bubbles either formed by a natural gas cavern under the region or bacteria that eat biological material and excrete methane or as UFO nuts like to propagate by space aliens or as ancient settlers believed by in fish spirits and goblins. what cannot be denied is the spectacular sight these enigmatic orbs decorate the Mundanity. 

5. PINK LAKE HILLIER 

Pink lake hillier Australia in Western Australia there was a unique visual treat that is nothing short of God gives. The holy photo opportunity nestled in lush emerald foliage and surrounded by the dense and deep sapphire blue of the ocean. Australia hides a phenomenon that will shock even the most jaded onlooker a series of bubblegum pink lakes. One of the most known lake hillier flies of the edge of the middle island in the rachet archipelago encompassed by a thinner ring of sand that adds beauty to its mystique.

what is more surprising than its Pepto-Bismol shade geologist James Garrick says is that nobody seems to be able to definitively explain its distinctive color so position abounds as to their natural green algae with high levels of beta-carotene a micro-organism is known as halo akia a high concentration of pink brine prawn but the chromatic splendor still manages to elude any real explanation.
