Top 15 strange natural phenomena (1)

Blue tide, glowing mushrooms, rainbow fire . are strange natural phenomena, rare to witness.

1. Blue tide

Bioluminescence inside the waves is caused by phytoplankton.

In the world there are many phytoplankton species capable of bioluminescence. The most common luminescent species, inhabiting oceans is 'dinoflagellate' algae, the algae that cause red tide. Dinoflagellate algae belong to single-celled organisms.

Dinoflagellate algae float on the surface of the sea and move around the waterways, creating electrical impulses around the proton, preventing water from getting into the microorganisms. These electrical impulses then produce voltage-sensitive proton channels, which activate a variety of chemical reactions, including the luciferase protein - responsible for forming neon blue light inside algae.

In September 2011, a blue tide at Leucadia Beach, California, scientists also discovered that some dinoflagellate algae contain dangerous toxins that are harmful to human health, the process of growth and development. fish and many other sea creatures. Besides, algae also use the luminescence ability as a powerful weapon to prevent threats from other organisms.

2. Mushrooms glow at night

Photoluminescent fungus is a poisonous plant, also known as 'ghost mushroom'.

Researchers believe that the fungus also shines in the way of a firefly, thanks to a mixture of luxiferin and luciferase. Luciferase is an enzyme that helps to support the reaction between luciferin, oxygen and water to produce luminescent solution.

However, until now, there is no evidence to confirm the presence of luciferin and luciferase on luminescent fungi. The reason why the fungus glowing until now is still a mystery without explanation. For fungi, the scientists theorized that they luminescent to attract insects to help them disperse germs to form new fungi.

3. Rainbow fire

In fact, the fire rainbow phenomenon has nothing to do with rainbows or fire. A fire rainbow is a special optical phenomenon, which has a multicolored pattern parallel to the horizon (also called five-colored clouds). This phenomenon occurs when clouds carry many countries of almost uniform size. These clouds diffuse or bend light, causing light to follow different wavelengths, or colors.

4. Nacreous clouds

Nacreous clouds look like thin films, gently curled up and then flattened out, spread out and then shrink in the sky in the morning and evening.

Nacreous clouds are often formed in extremely cold areas of the low stratosphere, with an altitude of 15-25km, directly above the troposphere clouds. The reason they shine so strongly before dawn and after sunset is because they are still exposed to sunlight.

This phenomenon is a direct consequence of people emitting too much methane gas, reacting with ozone and forming chlorine clouds. The appearance of nacre cloud is a worrying sign showing that the phenomenon of Earth is getting warmer.

5. Snow curls into a tube

Snow rolled into tubes is a rare natural phenomenon, they only occur when there is a harmonious combination of temperature, humidity, wind speed, terrain and snow conditions.

Snow rolls formed on flat bare land or rested slightly, the surface covered with a smooth layer of ice or hard snow. Snow will fall or pile on the ground. Strong winds will speed up the snow and curl little by little.

The new wet snow, clinging to the ice surface, the newly formed snow will slip and curl. The wind is the agent that moves the snow rolls to thicker.

When the snow is too heavy to wind, it cannot move or collide with obstacles to stop moving. Because they are only created when there are special climatic conditions, it is easy to understand why people are rare. Not only are they rare but they are also fragile. If the temperature rises or falls, they will collapse.

6. Cylindrical basalt forest

Blocks of basalt are formed by volcanic eruptions, they are erect stones, a rock formations are quite spectacular geometry, distributed in grid lines with 6 hexagonal shapes all the way .

This fascinating natural stone complex is one of the masterpieces of natural landscapes located in the coastal coast of Ireland.

7. Rain of animals

There are strange rains that carry thousands of toads falling from the sky. Rain phenomenon accompanied by other rare animals occurs more than "toad" rain, but has also happened in some countries in the world.

Explaining this bizarre phenomenon, most natural researchers have argued that at that time, a strong tornado had swept the toads and clones, after thousands of miles of road, when the whirlwind weakened vortex, rain appeared, these entangled animals also fell to the ground along with the rain.

However, this is only part of the explanation for the occurrence of strange rains. In fact, the rain accompanied by the appearance of "animal" species is still a mysterious phenomenon of nature that people are still trying to discover.
