Learn about the strangest and rare 10 natural phenomena in the world

1.1.Super Cell

SuperCell is the strongest and most powerful thunderstorm and has the ability to control local weather for up to 32 kilometers.

A phenomenon that is rare and common in areas such as the plains of Argentina, southern Brazil and Uruguay and the Tornado alley in the Great Plains region of America.

2. volcanic lightning

A phenomenon in which both lightning and volcano occur at the same time, a phenomenon puzzling scientists, they interpreted it occurs when the volcano sends charged particles wave shipments, which combine with the negative charges in the atmosphere, resulting in volcanic lightning.

3. Frosts

They occur in autumn and early winter. These flowers form when the air is cooler than the ice layer below, where the water vapor directly turns into frost, and the thin layers of ice form flowers-like shapes.

4. Rainbow Fire

A phenomenon common in the United States, during the summer, and is accompanied by fire, and is not related to the rainbow that appears in the winter, but it happens by chance when the line of the sun is equal to the distribution of snow masses of clouds, where these blocks play the role of glass prism, The light is analyzed into colors such as rainbow, and also takes the form of flame.

5. Vertical basalt

As a result of the refraction of lava flows in the cold, in a direction that is perpendicular to the original flow, they form unique formations. These forms vary depending on the rate of cooling of the lava flows, where rapid cooling leads to very small columns less than 1 centimeter in diameter Slow cooling causes larger columns.

6. Snow bars

This phenomenon was first discovered in the 1960s, but first filmed in 2011, during the documentary "Frozen Planet," a strange phenomenon that occurs when cold water flows into the cooler waters of the ocean and takes the form of ice tubes. These forms are fragile at the beginning, Then it becomes stronger when ice accumulates.

7. Water cisterns

They are swirls that occur on the surface of the water, formed in the shape of the hose. This phenomenon occurs in different places, especially in the tropics and subtropical regions, which are common in New Zealand, Antarctica, Great Lakes and Europe, To reach speeds of 305 kilometers per hour.

8. Ice cakes

It is formed when the air vortexes move above the surface of the earth, with the snow atoms moving in it. They vary in size. They can be up to two feet in diameter by wind. Their composition requires a wide ice surface and strong winds to move them.

9.sun dogs

This phenomenon, known scientifically as "parhelia," occurs as a result of the sun's rays on clouds with snow masses that act as a glass leaf that redistributes circular sunlight, producing a white halo around the sun.

This phenomenon occurs anywhere, at any time during the year, but it only occurs clearly when the sun is low in the sky.
