Rifting is the initial stage of continental collapse and the opening of the ocean during plate tectonic movements. It is the prototype of an ocean basin.
But not all rift valleys will evolve into oceans. For example, the prehistoric rift valley that stood in front of Lin Shuhang and Crazy General did not form an ocean basin because it stopped developing hundreds of millions of years ago.
According to the map of the island, after crossing this prehistoric rift valley and continuing for more than a thousand kilometers, you can re-enter the territory of the Titans and reunite with those giants you have not seen for a long time.
However, it is not easy to cross this prehistoric rift valley.
This prehistoric rift is hundreds of meters wide, and Lin Shuhang's "Desperate Leap" is of no use. Because his "Desperate Leap" can only jump about 100 meters at its furthest.
Of course, the "rock climbing skills" that the giants are proud of may be able to climb over this canyon, but the "rock climbing skills" cannot be used at any time and in any place.
Looking at the situation in the rift valley, it is very pessimistic. Because this is a very special rift valley. There are rivers in the valley, and they are not ordinary rivers, but extremely high-temperature volcanic lava.
Yes, you heard it right, this prehistoric rift is flowing with boiling magma!
Magma is a professional term in geology. When a volcano is active, not only steam, stones, crystal chips and molten clumps erupt from the crater, but also hot and viscous molten material overflows from the crater. The former is called
They are volatile matter and pyroclastic material, the latter of which is called a lava flow.
This kind of high-temperature, viscous, volatile molten material produced deep in the upper mantle and crust and whose main component is silicate is called magma.
Due to the heat preservation effect of the earth's crust, the temperature becomes higher toward the center of the earth. The earth's core is in a solid state due to high pressure. The high-temperature material under the earth's crust is in a liquid state, which is magma.
On today's Earth, if there is no plate movement, volcanoes will not erupt (except for the early Earth), and the Earth's internal energy is only slowly dissipated through rock conduction.
As the Earth spins slower and slower, plate movement and volcanic activity will gradually subside, just like the moon today, lifeless.
The magma activity in this rift originates from the continent 30km away and below 6km from the oceanic crust, which is the asthenosphere of the earth. However, the material of the asthenosphere is not magma. The asthenosphere is in a semi-plastic state under the huge lithostatic pressure. Only
When the pressure decreases, such as when the earth's crust cracks, it turns into magma and moves in the direction of low pressure. Secondly, when the temperature increases, magma can also form and melt the overlying rock layers to form a volcanic eruption.
Therefore, the geological conditions of the origin of magmatism are the cracks in the earth's crust (including oceanic crust), that is, the mid-ocean ridge rift valley.
In addition, there is also magma activity where the two continental plates collide, but the crust here is very thick. The thickness of about 60 kilometers allows the magma to cool only in the form of intrusive rocks, and there are few volcanic eruptions.
The magma overflowing from the surface is like molten steel freshly baked in a factory, red and hot.
According to scientists, the temperature of magma is generally between 900-1200°C, and can reach as high as 1400°C.
Under clear weather and good perspective, the relationship between the color of a lava flow and the corresponding temperature is:
White≥1150℃
Golden yellow ≥1090℃
Orange ≥900℃
Bright red (cherry red)≥700℃
Dark red≥550~625℃
Vaguely red ≥475℃
I lowered my head and looked at the bottom of the valley, and found that most of the magma flowing in the rift valley was dark red, which meant that the temperature of the magma was at least over 600 degrees. If you accidentally slipped and fell into this lava river, you can imagine what would happen.
, no matter how huge the creature is, it will become a wisp of scorched smoke, and there will be no chance to climb up.
Lin Shuhang had not lived enough yet and would never dare to take this risk easily, so he could only think of other ways to cross this prehistoric rift valley filled with hot lava people.
"How can we travel to the prehistoric Great Rift Valley?" Standing above the rift valley, looking at the hot lava river at the bottom of the valley, Lin Shuhang fell into deep thought.
"Isn't it easy to cross the rift?" Some viewers suggested: "Just make a ladder and climb over."
"Ladder?" This idea got other viewers talking.
Someone retorted: "Come on, old man, open your dog eyes and take a good look. The narrowest point of this rift valley is several hundred meters long. What kind of ladder is so long? Then again, even if the anchor has the ability to do this,
Plant a ladder several hundred meters long. If you have the skill and time to make a ladder, you would have taken a detour a long time ago, so why waste so much time here? What you are saying is simply unrealistic!"
"Yes, your idea is extremely stupid. If you have the time and skill to make a ladder, you have already passed by. Having an audience like you is simply the greatest misfortune for the anchor."
There was a quarrel in the live broadcast room about this.
"Since this Great Rift Valley cannot be crossed from the ground, what about in the sky?" Some viewers suggested: "Why not think about the problem from another angle? Find a way to cross it from the air?"
"Through the air?" Lin Shuhang was startled. He had to say that this alternative idea really aroused his great interest. Before, his mind had been fixed on the ground, and he did not think about leaping through the crack from the air.
valley.
Lin Shuhang asked with interest: "I'm very interested in your idea, old man. Tell me your suggestions. If I think it's feasible, I will definitely adopt your suggestions."
The viewer cleared his throat and began to express his thoughts: "Look, anchor, the narrowest point of this Great Rift Valley is only a few hundred meters away. For us ordinary people, this is an insurmountable and huge macro.
But don’t forget the issue of body proportions. You are a Titan, and your height is close to 60 meters. If you convert the proportions, this Great Rift Valley is only equivalent to a dozen of your height at most."
The other party is right. In the eyes of ordinary humans, this prehistoric rift is indeed an insurmountable huge gap. But don't forget that Lin Shuhang is a Titan. If converted into proportions, this rift is only a dozen or so at most.
Lin Shuhang's height, after all, his height is now close to 60 meters.
The man continued: "I have been following you silently since you started broadcasting. I found that you are a very special anchor. You have a smart mind and a pair of hard-working hands. My personal suggestion is,
You could try making a set of tools to fly across the chasm."
Hearing the other party's suggestion to make a set of tools to fly across the rift valley, Lin Shuhang felt that this idea was too absurd, just like the old man's previous suggestion to build a ladder, which was a bit unrealistic.
"Don't be ridiculous, old man." Lin Shuhang shook his head fiercely: "You overestimate my ability. You asked me to do a duster. I guarantee that my duster skills are the strongest on land and I can build airplanes.
I can't do it, because this is a barren prehistoric continent, where are the materials to build an airplane? I still know how much I weigh."
"NO! I didn't ask you to build an airplane. Not to mention that you can't do it by yourself. Even if I give you 100 helpers, you can't do it."
Lin Shuhang said dissatisfied: "Then you still suggest that I cross this great rift valley from the air? Are you kidding me?"
The audience member laughed and said: "Anchor, your thinking is too limited. Airplanes are not the only things in this world that can make people fly. As long as the power is strong, mountains can also fly."
Lin Shuhang frowned and asked: What about?"
"For example, rockets, kites, paragliders, heavy trebuchets, giant bows and arrows, giant slingshots, these things can allow you and the crazy general to fly across this great rift valley from the air."
Rockets? Kites? Paragliders? Heavy trebuchets? Giant bows and arrows and slingshots? This thought made Lin Shuhang's eyes shine as if he had seen a new world again.
Lin Shuhang banged his head and looked extremely excited: "Yes, why didn't I think of making these things to fly across the Great Rift Valley before?"
"Old Tie, your suggestion is good. If the Crazy General and I can successfully fly across this great rift valley, we will definitely give you a credit when we look back!"
"Haha, there is no need to remember the credit. As long as you bring more exciting live broadcast content to us die-hard fans in the future, I will be satisfied."
