We may think that human knowledge about the Earth is comprehensive and absolute, but that couldn’t be further from the truth. We at Sci-Tech Universe have compiled some of the rarest and most incredible natural phenomena that prove us almost totally ignorant of our planet.
St. Elmo’s Fire

Tower spires and mast tops are sometimes lit by ghostly fires, usually during a storm.
Medieval Europeans believed these dancing lights to be the promised gift of St. Elmo, the patron saint of sailors: legend has it he promised to pray for them and give warnings in the form of lights on masts.

A man from Hämeenlinna, Finland, discovered snow threads that looked like noodles on the lake near his house. He later learned that he could take these threads and make snowballs.
The threads may have been shaped by movements of wind and water before the fallen snow melted.

A dancing forest

There is a forest in Russia where trees are strangely bent, and scientists haven’t yet come to a conclusion about this phenomenon. Some think the reason is parasites, while others blame strong sea winds. Old-timers think this place is haunted.

Some thought these red or blue flashes that appear at great heights were alien spaceships. Only after the phenomenon was caught on camera in 1989 was it proved that the sprites are "distant relatives" of lightning.

Red tide is caused by enormous amounts of tiny red algae near the water’s surface, a phenomenon similar to water blooming. Red tides are dangerous to sea dwellers because the oxygen content in the water decreases, while hydrogen sulfide and ammonia increase. A number of scientists connect the red tide with the first plagues of Egypt, where the waters of the Nile turned to blood, killing the fish.

If you’re in the mountains and look away from the sun, you can sometimes see the shadow of a giant surrounded by a rainbow halo. This is actually the shadow of the watcher himself cast on the mist. Small drops fracture the light, which then form the halo around the shadow.
This phenomenon is most frequent on Brocken, a mountain in Germany. It was once thought to be the doing of witches on Walpurgis Night.

The Mekong River in Thailand sometimes erupts with crimson fireballs that rise 30-50 feet above the water and disappear. They usually appear in October, and there’s even a festival dedicated to this phenomenon. Scientists explain it as inflammation of gases rising from the river; locals believe the balls to be sent by Naga, a half-snake, half-human living in the river.

Valley of falling birds

In Jatinga Valley, India, birds have behaved very unusually for centuries: they circle very low, and some even fall to the ground semi-conscious.
Birds usually find their way by the sun and the magnetic field of the Earth. The reason for their strange behavior must be in geophysical anomalies.

The Baltic Sea anomaly

A strange object was found on the bottom of the Baltic Sea, looking like a UFO. Scientists haven’t yet come to a consensus about its origins. It’s made of basalt, so it is not a spaceship. Theories are that it’s a result of glacier meltdown or a secret Nazi military facility from WWII.

Brinicle — an icy "finger of death"
This phenomenon occurs due to different freezing temperatures in arctic waters of different saltiness. It looks like a sudden icicle growth that turns into an icy spring at the bottom. It freezes any water animal it touches to death.
Brinicle was first hypothesized in 1974, but its existence was only proven in 2011. There’s only one video of it, caught by accident by the BBC.

Ice circles on rivers

Perfectly round and slowly turning circles of ice are formed by eddy flows in rivers. A piece of ice begins to turn, grinding down its corners on the surrounding ice and becoming a perfect circle. The phenomenon has been reported in Scandinavia, North America, Germany, England, and Russia.

The Crooked Forest is located right outside of Nowe Czarnowo, West Pomerania, Poland. The grove contains approximately 400 pine trees with bent trunks. They were planted sometime in 1939, but why or who made them crooked is unknown.
A hidden ocean beneath the Earth’s crust

The image above shows the mineral called ringwoodite, and it’s peculiar because of its pressurized water content. Recent studies show that deep in the Earth’s mantle, encased in a shell of rare minerals, lies a vast ocean, whose overall volume may well be equal or greater than that of all the oceans on the Earth’s surface. Ringwoodite proves its existence, because this mineral only forms under conditions of the mantle, yet in presence of water.
