Chapter 29: Antarctic Meteorites (7)
Dosse finally closed the notebook, stood up and said, "All right! Brende immediately stepped forward and asked, "Dossie, where did this meteorite come from?" Dossi watched their findings with excitement in her eyes. I don't know where it came from, but what I do know for sure is that it's an iron meteorite. Probably from a metal-rich planet that floated in space for a long time and ended up at the South Pole. As soon as her words fell, several people showed surprised expressions.
Brende asked, "How do you know?" ”
Dossi smiled and explained: "I can deduce its material from its density, from its surface features, and from its weight. After speaking, he looked at the expressions of several people, and found that everyone was looking forward to her answer, "Hmm! This is the power of science, and through observation and experimentation, we can learn the truth about this world. ”
Fusco was deeply attracted by Dossi's words, and he looked at Dossi, his eyes full of admiration and yearning.
Vico came back to his senses, pointed to the meteorite and asked, "What about this meteorite?" Take it back or put it here? Dossi looked at the meteorite seriously, thought for a while, and then said, "We can take some samples from the meteorite and bring them back, and we can hand them over to the research department to study its composition and structure." ”
Brende nodded and said, "Good idea, then let's get started." With that, he took out his tools and began to cut the meteorite. Others also came up with tools to help Brende.
In the process of cutting the meteorite, Dossi explained to others as he observed: "The composition of meteorites is generally divided into three categories: stony meteorites, iron meteorites, and stony-iron meteorites. The one in front of us, based on its density and surface characteristics, I can preliminarily judge that it is an iron meteorite. ”
Vico listened and exclaimed, "Are these all treasures from space?" ”
Dossi nodded and said, "It can be understood that way. Meteorites are treasures in space, they carry information about the universe, and they are an important way for us to understand the universe. ”
After some time of hard work, they managed to cut a sample from the meteorite. Brende packed the sample into a box and carefully put it away.
Then, together, they put the meteorite back in its place and covered the incision with snow so that it would not be discovered by others.
They stood next to the crater, as if they saw it shining with a mysterious light, and their hearts were filled with awe. They knew that although the adventure was over, the mystery of this meteorite had just been revealed. They believe that in the days to come, they will embark on an expedition again, to find more mysteries, to discover more unknown secrets.
The five Antarctic elves held each other's hands tightly, and they knew that no matter how difficult the road ahead might be, they would walk it together. They have learned the importance of unity and friendship from this adventure, and they have learned that only by uniting can they overcome difficulties and find true treasures.
They looked at the starry sky in Antarctica, and their hearts were full of anticipation. They look forward to the next adventure, they look forward to discovering more secrets, they look forward to exploring more unknowns. They know that their adventure has just begun, and that their future is full of possibilities.
Dossie's Tips:
Hello everyone! I'm Dossie, and today I'm going to share with you - a gift from space - meteorites!
A meteorite is a rock or metal mass that comes from a celestial body other than Earth and falls to the ground without being completely burned up when it enters the atmosphere. Meteorites can be divided into different types such as stony meteorites, iron meteorites, and stony-iron meteorites.
The main component of stony meteorites is silicate, and a small amount of metallic elements such as iron and nickel are also mixed. They are usually black or brown in appearance, and they may also have unique features such as potholes and ravines on the surface.
Iron meteorites are mainly composed of iron and nickel and may also contain small amounts of silicates and other metallic elements. They are usually silver or gray in color, and may have distinct textures or furrows on the surface, indicating their extraordinary origin in the universe.
A stony-iron meteorite, as the name suggests, is a hybrid of a stony meteorite and an iron meteorite, and its unique structure and texture are even more fascinating.
And Antarctica is one of the largest meteorite collections in the world, because the environment of the region is very special, meteorites can be preserved here for tens or even millions of years without being weathered or polluted.
Antarctica, the end of this ice-capped world, is home to one of the world's largest collections of meteorites. The special environment here allows meteorites to be preserved for tens or even millions of years, without weathering and pollution. These Antarctic meteorites come from a variety of sources, including asteroids and comets, which are heated and melted as they enter the Earth's atmosphere, eventually forming meteorites. There are very many types of Antarctic meteorites, including stony meteorites, iron meteorites, stony-iron meteorites, etc., some of which also contain rare elements and minerals.
The study of meteorites is of great significance for us to understand the origin and evolution of the solar system, the chemical composition and evolutionary history of the earth. At the same time, Antarctic meteorites are also favored by collectors because of their scarcity and preciousness, and some meteorites have even achieved staggering prices at auction.
