From time to time, there may be phenomena that surprise us. Sometimes, the birth of some phenomena may even make it difficult for scientists to understand. This is due to the rarity and singularity of their occurrence. For many peculiar phenomena, it is lucky to be able to meet them, because they are rare and magnificent, but for other peculiar phenomena, the damage they cause is not what humans want to see. Today, we are going to share with you a few rare natural phenomena:5 peculiar natural phenomena that are hard to see on earth.

In fact, there have been many ground cracks on the earth. Perhaps the most famous of these is the Great Rift Valley in the African continent. It is one of the most famous geological regions on earth. Stretching more than 3,000 kilometers from the Gulf of Aden in the north to Mozambique in the south, it marks the division of the African continent into the Somalia and Nubian plates. Scientists estimate that within 10 million years, the Somalia plate will be separated from the rest of Africa, and then a new ocean basin will be formed.

Although this is An extremely slow process, but every once in a while, new cracks will appear, highlighting the power of the earth’s tectonic force. In recent years, a large crack 15 meters deep and 20 meters wide appeared near the small town of Maemash, west of Nairobi, the capital of Kenya, destroying a major road and several houses.

Nature sometimes creates things that remind us of human creation. For example, the pancake-shaped ice cubes that can be seen in the Antarctic and Arctic regions. This ice cube resembles a pancake. It has a round shape with a thin middle and upwards on all sides. These round objects are composed of foam or slush with ice on the top. When they float on the water, they collide with other objects to form a circle. Its edges are thought to be formed by rising temperatures during the day and colder nights.

At first people can I saw these birds perching on the railing, but when the vehicle passed by, they suddenly flew up. The flocks of birds are all over the sky, forming an incredible sight against the sun. Because there are too many cars, they have to leave the lane.

Although hail does not happen often, I believe many people have seen it. It is a solid precipitation, a sudden natural disaster. The hail rain is large or small, but the hail that most people see is either relatively small or does not cause much harm. But in human history, there have been some very severe hail rains. For example, in 2017, hail erupted in a town in central Argentina, which is easily reminiscent of the end of the world. The violent hail hit several cities and towns. In just 15 minutes, 1.5 meters high hail was dumped, and many vehicles were trapped in it. At first, local people took pictures of this rare phenomenon with their mobile phones, but as the hail became bigger and bigger, even after hail that was bigger than tennis, people realized its danger. Many vehicles were trapped by the 1.5-meter-high hail, and many vehicles and houses were dented by the hail. After the hail melted, they flowed on the roads of the town like a river.

Ice tsunami is a rare phenomenon in which a large amount of ice rushes onto land from a lake or sea. This rare phenomenon occurred in Lake Erie on the border of the United States and Canada in February last year. Strong winds hit there at the time because the extremely high wind speeds approaching 110 kilometers per hour pushed a lot of ice and water into the eastern coastline of Lake Erie. The strong southwesterly wind caused the lake water and ice to rise rapidly at the eastern end of Lake Erie, pushing the 9-meter-high ice dome into the residential area of ​​Hoover Beach and forcing people to evacuate there.
