10 amazing natural phenomena
We admire nature and draw inspiration from it, even when we don't fully understand it. For example, our ancestors took lightning strikes and thunderclaps for the rage of the gods, although today we know the cause of these phenomena. Nevertheless, some natural phenomena remain a mystery even today, in the age of enlightenment and science.

Snow rolls. They're snow rolls. When there is suitable snow in an open area — with an icy cold layer at the bottom and a wet warmer layer at the top — and a gusty strong wind blows, it is quite possible to observe this rare phenomenon. The wind rolls the snow into a kind of haystack, the size of an Apple to a car.
Tubular clouds. These ominous-looking clouds sometimes portend severe tropical thunderstorms, but more often form when the storm has passed. Cloud "pockets" occur when an updraft lifts the moisture-saturated air above the clouds, after which heavy particles of water and ice fall down.
Ice flowers. For the formation of this phenomenon, specific conditions are needed — late autumn or early winter, when the earth is not yet frozen and the plants draw water from it. The air temperature drops sharply and the juice of some plants — for example, Verbesina virginica-breaks out, instantly freezing in an amazing configuration.
Basalt columns. Basalt is a rock formed from solidified magma. When solidified, it cracks like ordinary dirt, only the process in this case can last for centuries. Where molten basalt came to the surface tens of millions of years ago and cooled relatively quickly, today we can see a stunning colonnade.
Cloud hole. It's called the "hole-like band of falling precipitation", aka fallstreak hole. Occurs when something like a flying plane, ordinary dust or precipitation from a higher layer disturbs the rest of the cloud of supercooled water droplets that remain liquid even at -40°C. due to a chain reaction, the water turns into ice, falling down and making a nearly perfect hole in the cloud.
Brinicle. This underwater stalactite, which grows from the lower layer of sea ice, is an ice tube that stretches to the bottom with water that is much more salty than it flows around. Brynikl is formed quickly and continues to grow, even reaching the bottom, freezing to death small marine life like starfish.
Volcanic lightning. Also known as a" dirty thunderstorm", this atmospheric phenomenon is lightning in a cloud of volcanic ash during an eruption. The mechanism of their formation is almost the same as in a normal thundercloud, but with the participation of fragments of stone, ash and ice particles that collide and generate electric charges.
Sliding stones. Boulders, crawling up the bottom of a dry lake Racetrack Playa in Death Valley in the US has excited the imagination of scientists since the mid-twentieth century. Recent studies have shown that stones move on specific ice "rafts" that freeze on cold winter nights and melt as summer approaches. This is when a strong wind can drive stones from place to place at a speed of up to 5 m/min.
Calasparra. These ice formations can be seen in the mountains, at an altitude of more than four kilometers, especially often found in the Andes. Their other name - "penitent snow" - is due to their similarity to the figures of penitent monks. When the firn — a densely Packed, long-term snow-melts in conditions of dry air and high standing of the sun, there are similar figures.
Light poles. Lunar or solar light reflected on ice crystals of a certain type hanging in the air — flat hexagonal or columnar-forms this rare atmospheric phenomenon. Most often it can be observed in cold regions, including Russia.
