Interesting geography story

Take some time out of your busy study to read interesting geography stories, let your brain relax and learn something. The following is an interesting geographical story I compiled for you. Welcome to reading.

Minamata Bay is a picturesque bay in Japan. For many years, fishermen in Minamata Town have been living on rich seafood. 1950, a strange phenomenon happened in the town. Some cats suddenly got strange diseases, walked unsteadily, kept cramping their limbs, and finally jumped into the sea and drowned. People think it is novel, but it has not attracted enough attention.

Before long, some local residents got this strange disease. Symptoms are very similar to those of a sick cat. At first, they were inarticulate and expressionless, and began to stagger. Later, their muscles trembled, their bodies bent like bows, they shouted wildly, and finally they died in extreme pain. This strange disease is the world-famous Minamata disease.

In recent 20 years, people have been looking for the cause of Minamata disease, dissecting the bodies of many patients and crazy cats, and it was not until 1969 that the truth was clarified. It turns out that there is a nitrogen fertilizer company in Minamata town, which uses mercury as a catalyst in the production process. The waste water and waste residue discharged by this company contain mercury. When mercury enters animals, it will paralyze the central nervous system and lead to death over time.

The seawater in Minamata Bay is polluted by this kind of mercury-containing wastewater and waste residue all the year round. Fish, shrimp and shellfish in the sea are all poisoned by mercury, and all kinds of creatures living in the sea form a? Food chain? Big fish eat small fish shrimp, small fish shrimp eat smaller zooplankton, zooplankton eat phytoplankton. Although the concentration of mercury in seawater is not high, it passes through? Food chain? It accumulates on big fish one by one, and with the gradual enhancement of biological drug resistance, the concentration of mercury is increased by 1 10,000 to110,000 times or even millions times than that of seawater. Cats and people eat aquatic products with high mercury content and get terrible Minamata disease.

This Minamata disease is not accidental, but actually caused by environmental pollution. Environmental pollution has seriously damaged the natural resources and ecological balance, affected the living habits of organisms and threatened the survival of mankind.

Life on the earth and its living environment constitute the largest ecosystem biosphere. Between organisms and the environment, between organisms, the circulation of matter and the flow of energy are continuous, and the ecological balance is maintained. The ecosystem itself has a certain self-purification ability. However, since the industrial revolution in the18th century, the population has been increasing, industry and agriculture have gradually realized mechanization, electrification and chemicalization, while the living standard has been improved, the environmental problems have become increasingly serious.

There are two reasons for environmental problems: one is caused by natural causes, such as various natural disasters and various endemic diseases; Second, it is caused by human factors, which is also a more important aspect, such as the arbitrary exploitation and abuse of natural resources and the arbitrary discharge of harmful substances; Improper construction of some large-scale projects; The continuous expansion of urban population has produced various urban environmental problems, such as traffic congestion, housing shortage, reduction of green area, air, water, noise, solid waste pollution and so on.

Minamata disease is the waste fire, waste gas and waste residue discharged from industrial production with the development of industrial production. Three wastes? ) the harm to the environment. Because? Three wastes? It destroys the natural self-purification ability and marine ecological balance of marine ecosystem, thus affecting the health of fish and human beings.

It is a historical necessity that mankind develops forward and the economy continues to prosper. While developing economy, human beings also cause environmental pollution, which in turn harms human beings. Therefore, we must pay attention to protecting the environment, effectively eliminate environmental pollution and protect the geographical environment on which we live.

Interesting geographical short story Part II Titanic was once proudly called in the history of world navigation? An unsinkable ship? The hull is equivalent to the length of three and a half residential buildings and is praised by the European and American press? Sea city? . 191April 15, it was carrying 2207 passengers and crew on its maiden voyage and collided with the same floating iceberg for only 12 seconds, resulting in the tragedy of 15 13 passengers being killed. This brilliant maiden voyage brought it the bad luck of being buried at the bottom of the sea.

Titanic set sail for new york from Southampton, England on April 19 12. The wealthy businessman Dajia and British and American celebrities who boarded the ship want to spend a wonderful week on this brand-new miracle ship. Below the deck, there are hundreds of immigrants living in the lower cabin. They want to cross the Atlantic and start a new life on the other side.

The first few days passed safely, but on the fourth day, the operator received an emergency telegram from the ship sailing ahead, reminding them that the iceberg was floating abnormally south and had reached the nearby sea area. On Sunday, April 14, Titanic received an urgent telegram with the same content. However, these warnings were not taken seriously by the arrogant crew. The first alarm was thrown aside and was not reported to the captain for several hours. The next two times were never sent to the command room. Just after dusk, the temperature began to plummet. Although the signs of iceberg approaching are very obvious, Titanic neither changed course nor slowed down.

After nightfall, Edward? Captain Smith set up an iceberg observatory. At 23: 40, the lookout first found the iceberg, and the duty officer ordered a sharp turn to the right chord. But it's too late. The iceberg knocked the outer wall of the ship's string open a gap 100 meter long. Most passengers only felt a slight vibration, which hardly attracted anyone's attention, but the engineers on board decided that the ship was hopeless after inspection. They think that if there are only four water tanks on board 16, the ship can still float on the water, but unfortunately, the outer walls of the five bottom tanks are torn by icebergs. Most of the passengers in the third class got up because the floor of their room had been flooded by the sea. The operator uses Morse code to send out the latest SOS distress signal, which is the first time to use this signal in a shipwreck. At midnight 12: 05, according to the captain's order, the lifeboat began to launch.

Passengers don't know that all lifeboats have only 1 178 seats, which can only accommodate half of the total number of people, but according to the laws at that time, this life-saving condition is quite sufficient. At first, the passengers did not panic. They don't believe there will be any danger at all, because the Titanic is? Never sink! ? It was not until the hull tilted dangerously that they lost their previous composure. Women and children leave the ship first. The first-class passengers boarded the lifeboat first, and only four women were killed in the shipwreck. Of the 272 women in second class and third class, only 96 survived. At one time, the door of the third-class cabin leading to the deck was even locked to prevent the passengers below from rushing onto the deck. On the increasingly inclined deck, the band has been playing the music of the mob.

At 2: 40 in the morning, the Titanic almost stood upright in the water, and then plunged into the Atlantic Ocean at a depth of 3,000 meters. The immigrants who stayed in the dark cabin were buried at the bottom of the sea with the Titanic, and all the people on the deck were thrown into the cold sea, which became the funerary objects of the famous shipwreck in this ice sea.

The iceberg that led to the sinking of this luxury ship is actually not a mysterious thing, but a huge piece of ice floating in the polar waters. Every spring and summer, it is formed by the rupture of polar ocean ice due to rising temperature, and gradually disappears when drifting to temperate and tropical regions. Their size varies greatly, and large icebergs can reach several kilometers long. Such a behemoth is a great threat to maritime navigation.

The sinking of Titanic shows that the power of nature is enormous, and human beings must not be blind and arrogant. We must pay enough attention to various natural phenomena, otherwise tragedy will be inevitable.

Once upon a time, there was a landlord who was obsessed with money. He will do anything for money. One day in late spring and early summer, two generations of love saw the rich cheat money by betting with the poor, and they were thinking about how to punish the rich man. Afandi said to the rich man:? Do you know how long a day and a night are?

The rich man said without thinking. A day and night is a day. You don't have to ask.

Two generations of love say:? What you said is not entirely correct. In some places, a day and night is not a day, but a year. ?

Wang Man, a rich man, said angrily. Every day and night is a day there, and there will be a place where day and night are a year! Do you dare to bet with me

Avanti asked? How much to bet

Onlookers are also talking, a day and a night is a day, how can it be a year? Speaking of two generations of love, the rich man knows that he is very smart, but he thinks that this boy always destroys my great events, and he must show his past cowardice today. Thinking of this, the rich man sneered: bet 120 gold? !

Afandi smiled and said:? One hundred and twenty is one hundred and twenty. I am willing to write down written evidence as evidence and never go back on my word. ?

The rich man was so happy that the two sides made a bet in public. The audience is sweating for two generations. Once they lose, where can we find the one hundred and twenty gold?

Two generations of love brought the rich to the north, camping all the way, and cold and danger threatened them all the time. The rich man has never suffered so much, but at the thought of 120 gold, he is still reluctant to take risks with two generations of love. Walking and walking, the days are getting longer and longer. Finally, one day, they went through all the hardships and came to the North Pole. A day or two passed, and before sunset, the rich man was in a hurry. After five or ten days, the sun has not set, and the rich are puzzled. January and February passed, but the sun still didn't set, and the rich man was already disheartened. Finally, the rich man almost ate up the dry food he brought, but the sun still didn't go down. In order to go back alive, the rich had to give up.

Everyone knows that one day and night is equal to one day, that is, 24 hours. Why is a day and a night in the Arctic a year?

The earth revolves around the sun while rotating. The rotation of the earth around its axis from west to east is called rotation. One revolution of the earth is a day and night, with 24 hours. The movement of the earth around the sun is called revolution, and the earth makes one revolution, that is, one year. An important feature of the earth's revolution is that the orbital plane and axis of the earth's revolution always remain 66.5? And the North Pole always points near the North Star. Because of this important feature, during the earth's revolution around the sun, the sun sometimes shines directly in the northern hemisphere, sometimes in the southern hemisphere, and sometimes at the equator. In a year, the direct point of the sun is always at 23.5 north latitude? 23.5 degrees south latitude? Move back and forth between.

On March 2 1 every year, the direct point of the sun is at the equator, and the Arctic sun does not set all day. 24 hours a day is spent in the daytime. This is an extreme day. Later, as the direct point of the sun moved northward, the polar day gradually expanded, and by the summer solstice in the northern hemisphere, the polar day expanded to the Arctic Circle. After that, the direct point of the sun stopped moving northward and began to move southward, and the polar daytime range of the Arctic gradually narrowed. Daylight saving time in the Arctic will not end until around September 23rd, when the sun will directly cross the equator again. During this period, the closer to the North Pole, the more days the polar day lasts, and the polar day lasts 19 1 day. During this period, there was no night in the Arctic, and it was all day, that is, half a year's day.

After the autumn equinox in the northern hemisphere, the sun shines directly into the southern hemisphere, and the North Pole begins to block the sun all day. I spend 24 hours a day in the dark, which is an extreme night. Until the vernal equinox in the northern hemisphere the following year, the North Pole was spent in a long night. The closer you get to the North Pole, the more days the polar night lasts. The number of polar nights in the Arctic is 174 days. During this period, the North Pole was dark for half a year.

The situation in Antarctica is opposite to that in the North Pole, but the days and nights are different from those in the North Pole. So we say that the North and South poles, a year is a big day and night, half a day, half a night.
