What is the ocean called the earth? Ocean-the heart of the earth

The ocean blood of the earth

I think the first one is better.

Forests are called the lungs of the earth. Auxiliary function of photosynthesis of green plants: absorbing carbon dioxide to produce oxygen.

Because it exceeds the consumption of respiration, the oxygen of the earth is mainly provided by green plants, and some of them also absorb some other harmful gases. So it is called the lung of the earth.

Paper and disposable chopsticks are made of wood, so the forest must be cut down, which will destroy the forest. If the forests that absorb carbon dioxide decrease, it will lead to the greenhouse effect.

Forests are the lungs of the earth. Wetlands are called the "lungs" of the earth. Forests are the lungs of the earth. Wetlands are called the "lungs" of the earth.

-Wetland is called the "kidney" of the earth!

Why is the earth called the global village? Because the world is developing towards integration, the development of information industry and transportation makes the communication of the whole earth more and more convenient and close, just like in the same village. After all, the reason why the earth is called the global village is because of the integration of the world! Hope to adopt!

Lesson 29 Why is the earth called the global village? This is a metaphor for the earth. With the rapid development of modern science and technology, the distance between time and space on the earth is shrinking, and international communication is more frequent and convenient. The whole earth is like a small village in the vast universe.

With the emergence of electronic media such as radio, television and internet, and with the rapid development of various modern modes of transportation, the time and space distance between people has suddenly shortened, and the whole world has shrunk into a "village". The term "global village" was first put forward by Canadian communication scientist M McLuhan in his book Understanding Media: An Extension of Man.

This swamp is called kidney of the earth. Why? Marsh is a kind of wetland,

The definition of wetland in the Convention on Wetlands is specifically expressed as follows: "Wetland refers to a water body with static or flowing water, or fresh water, brackish water or saline water, whether natural or artificial, long-term or temporary swamp, peat land or water body, including water body with water depth less than 6 meters at low tide." According to the broad definition of wetland, rivers, lakes, swamps and coral reefs are all wetlands; In addition, wetlands also include artificial wetlands, such as reservoirs, fish (shrimp) ponds, salt ponds, rice fields and so on.

Swamp can play an important role in resisting floods, regulating runoff, purifying water pollution and conserving water resources, so it is called kidney of the earth.

What is an ocean-going ship because it can resist some risks?

Not yet stable.

The ocean is called the hometown of life on earth. What is the reason? Marine life began with single-celled organisms and gradually evolved. Coastal fish can grow feet on shore, some adapt to land and enter the jungle, and then gradually evolve into various types of life. If traced back to the source, basically all life evolved from the ocean.

It can be said that man evolved from fish, because scientists also found five-finger type in deep-sea fish species. Hope to adopt!

Why is the wetland called kidney of the earth? Wetland (a kind of wetland) is a kind of resource and plays an extremely important role in protecting the environment. Wetlands can regulate floods and droughts caused by uneven precipitation; A large number of water surfaces such as lakes, rivers and reservoirs and their aquatic plants can adjust the climate; The natural characteristics of wetland vegetation can prevent and reduce the erosion of coastline, estuaries, rivers and lakes; In low-lying coastal areas, the basement is permeable, and fresh water is generally located above deep salt water, which is usually maintained by coastal fresh water wetlands. Therefore, wetlands can prevent seawater intrusion, ensure water supply for ecological communities and residents, and prevent land salinization; The water flowing into the aquifer from the wetland can become a part of the shallow groundwater system and can be stored and replenished in time. Wetlands can be used as direct water source or supplementary groundwater, and can effectively control floods and prevent soil desertification, and can also intercept sediments, toxic substances and nutrients, thus improving environmental pollution; It can store carbon in the form of organic matter, reduce the greenhouse effect, protect the coast from wind and waves, and provide clean and convenient transportation ... It is called "kidney of the earth" because of its rich and beneficial functions.

Why is Mars called the earth brother? What is certain now is that the "Tasis" mountain range on Mars, like the Hawaiian Islands, was formed by the drift of the crustal plate. The "Nice in Malinet" Canyon, which is 6 times longer and 8 times deeper than the Grand Canyon in the United States, was formed for the same reason as the Great Rift Valley in East Africa. These are the conclusions drawn from the magnetic analysis of rocks collected by Mars. It can be concluded that Mars is neither lifeless nor cold forever. Moreover, the formation period of the "Tarsis" mountain range on Mars is the same as that of the "Marinenis" Canyon on Earth, the Hawaiian Islands and the Great Rift Valley in East Africa. So there are many similarities between the landform on Mars and the earth. Although the research on this is not comprehensive, scientists are not disappointed because they have found the key to open a new field. Jack Connani, a researcher at NASA, said: "Based on the study of the structure of Mars, we have been able to explain some obvious features of the surface of Mars. But what is more rewarding is that we have now drawn a more accurate map of Mars. " In September this year, NASA published a research result, which showed that some drastic changes had taken place on the surface of Mars. Experts believe that there has been an earthquake or "global warming" on this red planet. However, all these findings may not be authoritative, because they are only obtained by studying the data returned by the detector, and the service life of the detector is now three times that of the expected life. From near to far from the sun, Mars is the fourth planet. To the naked eye, it is a striking bright lux star. It travels slowly among the stars. When looking at Mars from the earth, it sometimes goes straight and sometimes goes backwards. The darkest apparent magnitude of Mars is about+1.5, etc. And at the brightest time, it is brighter than the brightest star Sirius, reaching -2.9. This is because the Earth and Mars are in their respective orbits, and the distance between them is always changing. Mars is as bright as fire, its brightness is constantly changing and its position is uncertain, which is confusing. So China called Mars "sparkling" in ancient times. In western ancient Roman mythology, it was imagined as Mars, the god of war in armor and covered in blood, that is, Ares in Greek mythology. Ares had a noble life. His father is Zeus, the king of the gods, and his mother is Hera, the queen of heaven. Astronomically, the symbol of Mars is the combination of the spear and shield of Mars. Mars is the fourth planet in the solar system, but it is also the innermost planet. Mars, English name Mars, is the god of war in Roman mythology. It is about 265,438+0.7 million kilometers away from the sun, and its striking red exterior makes it difficult to be observed at night. When the average gas temperature of Mars is -63℃ and the rotation period is 24.6 earth balls, the common rotation period is 687 earth ball days. Like the earth ball, the scene at four o'clock is different. The Martian mass is 0.64 185x 1024 kg, and the gravity field intensity is 3.69ms-2. Mars used to have water, but now it is almost exhausted, but the poles of Mars should be covered with ice. There are two satellites: Desmos and Hobbes. The atmosphere of Mars consists of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon, 0. 13% oxygen, 0.08% carbon monoxide, a little water, nitrogen oxides, neon, krypton, xenon and (HDO). Mars has many characteristics similar to that of the earth. It is 227.94 million kilometers away from the sun, about 1.5 times the distance between the sun and the earth. The angle between the rotation axis and the orbital plane is 24, which changes all the year round like the earth. It is less than half the rotation of the earth, that is, 24 hours, 37 minutes and 22.6 seconds. So the length of day and night of Mars and Earth is basically the same, but the period of revolution around the sun is almost equal to two years for Mars. Because Mars is far from the sun, its period of revolution is 687 days. Mars is about half the diameter of the earth; 1/6 smaller than the earth; The mass is only110 of the earth; The atmosphere of Mars is much thinner than that of the earth. Its main components are carbon dioxide, accounting for 95%, nitrogen accounting for 3%, and a very small amount of oxygen and water. The average temperature of Mars is minus 23 degrees Celsius. Due to the thin and dry atmosphere of Mars, the temperature difference between day and night is very large, which is much larger than that on the earth. Due to the low surface temperature and low air pressure on Mars, carbon dioxide and water in the atmosphere are almost saturated. As long as the temperature drops slightly, carbon dioxide and water vapor will condense. There is little water in the atmosphere of Mars. Scientists estimate that if all the water ice on Mars melts into water, only an ocean with a depth of 10 meter can be formed on the surface of Mars. Compared with the vast ocean on the surface of our earth, the water on Mars is negligible. Because Mars is a close neighbor of the earth. It shares many characteristics with the earth. They all have satellites, moving sand dunes, sandstorms raised by strong winds, and white ice caps at the north and south poles, except that the ice caps on Mars are dry ice. Mars rotates once every 24 hours and 37 minutes, with an axis inclination of 25 degrees, which is almost the same as that of the Earth. There are obvious seasonal changes on Mars, which is its main similarity with the Earth. But beyond that, Mars is very different from the Earth. The surface of Mars is a desolate world, and carbon dioxide in the air accounts for 95%. The dense carbon dioxide atmosphere causes the high temperature on Venus, but on Mars, the situation is just the opposite. The atmosphere of Mars is very thin, and its density is less than 1% of the earth's atmosphere, so it is impossible to store heat. This causes the surface temperature of Mars to be extremely low, rarely exceeding 0℃. The lowest temperature at night can reach-123℃. Mars is called the red planet, because its surface is covered with oxides, so it appears rust red. The surface of Mars is mostly desert, with a lot of red oxides, ochre gravels and solidified lava flows. There are often violent winds on Mars, which can raise dust and form a super-large sandstorm that can cover the whole planet of Mars. Every sandstorm lasts for weeks. Because Mars is similar to Earth, it has always been considered that there is the possibility of extraterrestrial life. Recent scientific research shows that there is no proof of life on Mars. On the contrary, there are more and more signs that Mars is more like a barren and dead world. Nevertheless, some evidence still points out that there may have been life on Mars. For example, the analysis of a meteorite from Mars found in Antarctica shows that there are some tubular structures similar to bacterial fossils in this stone. All these continue to interest people in the existence of life on Mars. Let me show you some information: the ecliptic angle of the earth is 23 degrees 27 minutes, and the ecliptic angle of Mars is 24 degrees 37 minutes, which makes them have similar seasonal changes; The rotation period of the earth is 23 hours and 56 minutes, and that of Mars is 24 hours and 37 minutes, which makes the human biological clock completely adaptive if you want to immigrate to Mars. The distance between the earth and the sun is 1.0 astronomical unit, and that of Mars is 1.6 astronomical unit, which makes the surface temperature of Mars not too different from that of other planets. Mars has a thick atmosphere with signs of flooding ... and there are many more to list. It is very rare to find such a planet like Earth in the universe.
