World special geographical phenomenon 1 the craziest mysterious geographical phenomenon

1, red tide

The phenomenon of red tide is not that blood covers the ocean, but that algae and plankton are numerous and flood the waters. In some cases, the aggregated microorganisms dyed the seawater bright red. Some red tides are harmless, but some, such as toxic substances in the China Sea, will harm marine life.

2. monarch butterfly migration

These orange and black butterflies travel across a large area of the United States and migrate collectively because of the weather. The colder the weather, the monarch butterflies will migrate farther south to ensure warmth. The journey across such a long distance is so long that no butterfly has made it all the way, so they gave birth to as many children as the forest and let them fly on. The trip was a great success.

3. Milk cloud

Although sometimes called "European clouds", these clouds, which are mainly composed of ice, are more like honeycomb suspension. They stretch for hundreds of miles and seem static and threatening-reasonable. The appearance of such clouds is a warning to storms, extreme weather and even tornadoes.

4. Flame Rainbow

There is an atmospheric phenomenon, which only occurs when the sun is high and sunlight passes through clean high clouds, especially those composed of hexagonal crystals. Sunlight shines through the clouds to the vertical side, scattering and showing a dazzling spectrum, reminiscent of a wide range of rainbows. Now we know the real reason for these rainbows. If we didn't know them, maybe they would be more dazzling!

5. Taos hum

In the small town of Taos, New Mexico and other parts of the world, low-frequency buzzing can often be heard. Most of the buzz comes from things related to machinery and industry, but no one can be sure of the source of Taos' voice. Even if the sound in the building is enhanced, only 2% people can hear it, so Taos' hum is hard to trace.

6, fox fire

These luminous mushrooms can only be found in tropical areas and damp rotten bark in late summer, and can only be widely seen in the wettest season. However, the light they emit is far from the artificial light we are used to. The latest evolution of this luminous mushroom was discovered several years after it was collected in a national tourist park near Sao Paulo, Brazil.

7.blue hole

Although they are usually round, these underwater caves can be of other shapes and sizes. The main reason is that an underground cave collapses into an opening when it is extended. The deeper the hole, the bluer it is. There are blue holes in Belize City, Egyptian Red Sea and Caribbean Sea, but the deepest one is Deanes Blue Hole in Bahamas.

8.sandstorm

Sandstorms are common in the desert, and the reason is not mysterious. Usually the wind only blows up some dust and then flies away. But if the wind blows up too much dust at a time, it becomes a terrible force, which can destroy fields and even cause casualties. In fact, some sandstorms are so big that they can be seen from space.

9. Aurora

It is usually called aurora because the sun emits a current called plasma, which is emitted by high-energy charged particles running in outer space at a speed of 1000 km per second. This plasma flow from the sun is called the solar wind. When it interacts with the earth's magnetic field, the particles are captured by the ionospheric magnetic field and move with it. So only when the particles on the earth collide with the solar wind, the northern lights are obtained and the southern lights are obtained.

10, Moroccan goat tree

It is said that the reason why goats only climb some trees that grow in Morocco is that this tree produces an olive-shaped fruit. Some farmers deliberately climb trees with goats, not out of curiosity, but because goats spit out the seeds in their fruits, which can be used to make Moroccan nut oil needed in cooking and cosmetics. Unfortunately, these trees and fruits are disappearing because goats climb too much.

1 1, lucid dream

The idea of controlling dreams with self-awareness during sleep is popular because of Inception, just like controlling objects in virtual reality simulation. The Greek philosopher Aristotle once observed that when a person falls asleep, something in his consciousness will mark that what happens next is just a dream. Many people have experienced this phenomenon, and even Baidu has a strategy, although it may be time-consuming.

12, snow roll

This phenomenon of big snowballs rolling down the mountain has been found in North America and Britain. Snowballs roll like tumbleweeds and get bigger and bigger like ordinary snowballs. But because the middle part is fragile and not as strong as other parts, the wind will blow holes in the middle-just like doughnuts. Because of the bad formation conditions, snow rolls are rare. Once found, it will be enough for Wang Xingren to grab a headline.

World Special Geographical Phenomena 2 Top Ten Strange Geographical Phenomena in the World

The World Islands

1, the "world island" of the United Arab Emirates.

The World Island is an artificial island with an area of 5-5 square kilometers, including a beach of about 1 square kilometer. Located in the waters near Dubai, United Arab Emirates, it consists of 300 small islands with an area ranging from 20,000 to 80,000 square meters. The shapes of these islands have been carefully designed to form the shape of a country or a region, which looks like a map of the world as a whole.

Barnaway terraces

2. Barnaway terraces in the Philippines

Barnaway terraces are also called "the eighth wonder of the world" by some people. If measured from beginning to end, the total length of terraced fields in Barnaway is 22.27 million kilometers. Besides, such a huge project was actually built with original tools. It has been 2000 years since the local people built huge terraces to increase the farmland area.

Rock of Gibraltar

3. Rock Hill, Gibraltar

The majestic rock mountain of Gibraltar is the product of the violent collision between the African plate and the European plate about 55 million years ago. For many years, this rocky mountain has been used as a fortification by the British, and a complex underground exit and tunnel system has been built. People often use "as strong as the rock mountain of Gibraltar" to describe the military bases in this area.

Joseph Glacier, New Zealand

New Zealand's unique ice and snow environment has created the natural wonder Franz Joseph Glacier, and the length of the glacier is still increasing. According to the records of scientists in 2005, Franz Josef Glacier grew by 297 18 meters every day. Joseph Glacier has a history of more than 7000 years since its formation. Including the part extending to the ocean, the total length of the glacier is at least 1 1 mile.

5. Carlsbad Cave, USA

A long time ago, Carlsbad Cave was once a huge deep cave, where countless marine life lived. After 200-500 million years, due to the evaporation of a large amount of water, the cave that used to be an ocean paradise became the most fascinating rock concentration camp in the world. Here, visitors can still find stalactites and stalagmites containing limestone. In addition, 6,543,800 Mexican tailless bats have also settled in the giant cave. Carlsbad Cave is 480 kilometers deep, and the part that human eyes can see only accounts for one tenth of the whole cave.

6. Stone Forest in Kunming, China

People who travel to China and Yunnan will not miss the Stone Forest in Kunming. The stone forest covers an area of 12 square kilometers and consists of a large area of surface limestone. Now people see the Kunming Stone Forest, which has undergone at least 200 million to 700 million years of natural transformation. Visitors here especially like to visit the strange "wind tunnel". From August to165438+1October every year, gale will visit the wind tunnel every 30 minutes, and the stay time is about 2 to 3 minutes.

7. The largest iceberg in Antarctica

So far, the largest iceberg in the world discovered by human beings is the B 15 iceberg in Antarctica. B 15 iceberg area 1 1, 3.96 million hectares. On June 5, 2003, iceberg B 15 broke into two parts in the southern waters of New Zealand, and split into two icebergs. The fracture of B 15 iceberg has caused serious consequences: the ocean was suddenly blocked by icebergs, and a large number of penguins died.

8. Canada's "Magnetic Mountain"

Cishan is located in moncton, New Brunswick. This strange phenomenon was discovered in the 1930s, when the driver claimed that his car was dragged by a wonderful force when driving on the rolling slopes of the city, even when the engine was turned off. In fact, the driver's experience is just a bizarre illusion, which is caused by the ups and downs of the terrain.

Silbury mt

9. Silbury Hill in England

Wiltshire people in England are most proud that their hometown has the largest man-made earth mountain in Europe-Silbury Mountain. This man-made mountain, which is 39 meters high and covers an area of 2 hectares, was built around 2500 BC. Silbury Mountain is mainly composed of chalk, and it takes 6,543,800 man-hours to build it.

10, Turkey's "Elf Chimney"

Capadocia's so-called "elf chimneys" are actually some super-large conical rock formations. The soft rock resembles a conical spire, and the top of the spire is endowed with a softer basalt "hat" by nature. The charm of "fairy chimneys" lies not only in their peculiar appearance, but also in the fact that great natural architects have turned them into natural apartments suitable for living after countless times of wind and rain washing.
