In recent years, earthquakes and volcanic eruptions have been reported around the world, and this series of geological events has caused many people to wonder: what's going on inside the earth? Why are you so uneasy? Actually, it's all inextricably linked to plate construction. Do we really understand that
There's more than six big plates
It is generally accepted that the six main plates on the surface of the earth are the pacific, indian ocean, asia-europe, africa, america and antarctica. It's worth noting, however, that this is not all true! In fact, there are a number of small plates in addition to the six. The asia-europe plate, for example, breaks down the south-east asia plate and the philippines, arab, turkish, aegean and others. The american plate can also be divided into north and south american plates, and the indian ocean plate can be divided into indian and australian plates. It's not as simple as that. If it's just the six plates, it doesn't make sense. Can we see the complex geological conditions and not solve them? Of course not
And more importantly, these plates, no matter how big they are, they're still moving. Like the pacific plate, the new ocean crust that emerges from the mid-east pacific ridge moves west at an average of 5 cm per year, moving 10,000 km over 200 million years. How do you understand the changing landscapes on the surface of the earth if you keep thinking the plates are static? It's not true
So, don't underestimate the division of the plate, get to know it better, and it's really good for us to know the temper of the earth. In any case, the plate construction is far more complex than can be imagined, not just the six large plates on the surface。
Amazing finding: plate movement is not simply drifting
Many people may think that the exercise of the plate is simply moving around the surface of the earth, as if the ship was floating on water. Hey, that's a big mistake! The plate structure, also known as the global geodetic tectonics, refers to the massive horizontal movement of the rock coop on earth, not only with respect to the crust, but also to the top of the top mantle below moho. It's not a simple drift between aluminum and magnesium; it's a rock coil that moves like a conveyor belt across the mantle. Can this be the same? If that's the case, it's too simple to think of this complex operating mechanism on earth! Don't we want to figure out how the earth moved
It's worth noting that the plate is even more spectacular at the intersection. In general, the crust within the plate is more stable; the crust of the plate is more active in the area bordering the plate, and the world's volcanoes and earthquakes are concentrated in areas bordering the plate, such as the pacific rim and the mediterranean-himalayas. Two plates are fractured and often form a rift valley (e. G., the great canyon of east africa) or an ocean; two plates collide, often forming mountains on land. If it's too simple to think about plate motion, these geological wonders can't be understood。
So let's not be naive about the fact that board movement is a simple drift and that it's true how it moves, so we can better understand the geological transformation of the earth。
Unforeseen: the impact of plate construction is beyond imagination
Maybe some people think that plate construction has something to do with the formation of mountain water on the surface of the earth. Well, that's a little underestimation! The theory of plate construction has a great impact on geology and biology. It divides the top layers, minerals, flora and fauna of different continents and can be explained almost exclusively by the theory of plate construction. If the impact of plate construction is ignored, many questions about biological distribution and the distribution of mineral resources cannot be answered. Don't we want to solve these puzzles
More critically, the continued movement of the plates is changing the face of the planet over time. New mountain ranges may rise in plate collisions, and new metropolitan areas may be formed where the plate is fractured. It's all about plate construction. How can you understand how the earth has slowly become what it is
So, don't underestimate the impact of plate construction, which is quietly shaping the entire planet。

The science of plate construction, from birth to development, has experienced many setbacks and is constantly being refined. Now we know all its secrets, but that's not enough. There's a lot of unknowns inside the planet that we're going to explore. You know, the next time a geological wonder comes, can we say more precisely what the plate structure is behind it
In short, the matter of plate construction, which is complex and interesting, can give us a better understanding of the earth in which we live. Don't you know anything about it
