Continuing from the previous chapter, if you don't want to read it, you can't read it" Each silent crater on the surface of the planet shows that they have had a prosperous era in which they have been, but why is it that only the volcano of the earth is still unwilling to be lonely, and the roaring magma is not telling us the story of its own experience" "However, the question arises. ”"Unlike other planets, the volcanoes on Earth have not stopped erupting, and the number of earthquakes on Earth is significantly higher than on other planets, which indicates that the lava in the Earth's interior is still very active and the temperature is still high, and it also shows that the rocks formed on the Earth's surface are not capable of completely blocking the hot lava.""
The layers of rock on the earth's surface are not thick enough, and lava will often erupt through lava channels to form volcanoes or lava fluctuations, which will impact the earth's crust and cause earthquakes.""
Through the search of information, we know that compared with other planets, the thickness of the Earth's crust is indeed one of the thinnest of the planets and their moons in the solar system, with an average thickness of only 30 k, which is even thinner than the Earth's moon moon, while the crust of other planets is usually between 60 and 100 k."
Bai Hao could only listen quietly, "So, what kind of situation can cause the phenomenon that the earth's crust is thinner than the crust of other planets?"
"If the earth has the same cooling process as other planets, then the average thickness of the earth's crust should be about 100k, at least 60k, but in fact it is not." ”"The reasonable explanation for this situation is that, first, the material that makes up the earth is different, and the drop in temperature is different from that of other planets, and second, the formation process of the earth's crust is disturbed by external factors, and some kind of object has become a wall that hinders thermal radiation.""
Our knowledge tells us that we don't take the first interpretation to think that Earth is inherently different from other planets.""
For an object that relies on radiation to lower its temperature, it is first necessary to ensure that its temperature can be transferred to the surface relatively smoothly from the inside to the outside without being hindered.In this way, the overall temperature can be evenly dissipated, and if the internal temperature cannot reach the surface normally, the heat radiation to the outside world cannot be carried out normally. ”"So, does the Earth's shell be thinner than other planets to accelerate the Earth's temperature drop, or slow down the Earth's temperature drop" "If the Earth is an ordinary planet, then there is no reason why it is thinner than other planets.Conversely, if the surface of the earth is in the process of changing from a liquid state to a solid state.If the heat transfer channel is isolated by a thin shell in advance, then.The Earth's thermal radiation is also hindered, and the temperature drop is slowed down, which in turn makes its shell less thick than it normally would. ”"Based on the above situation, we put forward a set of hypotheses about the formation of the earth's environment.""
Hypothesis 1: In the process of the earth's evolution, and it was still in the liquid state, it suffered from sudden low temperature cooling, which led to the premature lithification of the earth's crust, so that the high temperature in the earth's interior could not be transmitted to the earth's surface normally, thus forming the earth with high internal temperature and thin rock layers.What kind of material is the earth subjected to that cooled down and caused the earth's crust to form prematurely?"
"It is clear whether the atmosphere is rocky or seawater, and our eyes fall on the seawater. ”"Hypothesis 2: Water causes the early formation of the earth's crust The atmosphere does not cause the earth to form the crust in advance, and lava itself does not form the earth's crust in advance for no reason, but water is fully capable of this.According to the physical properties of water, water has fairly good fluidity at room temperature. ”"With enough water, it is entirely possible to solidify a hot liquid surface of the Earth into a solid shell in a short period of time, thus blocking the Earth's passage of heat into space.Very lucky.We do have a large amount of water on the surface of our planet that can accomplish this task. ”"The second hypothesis we get is that the presence of water caused the early formation of the Earth's crust.""
Hypothesis three: Water is a foreign object to the earth.Obviously, here we deny that water is a product of the earth itself, and we do not think that the planets themselves carry so much water.One reason is that there is no room for such a substance as water inside a hot liquid.So, where does the water on Earth come from, and are there any stars in space that can provide water?"
One possibility is the comet", "Hypothesis 4: coincidence, or coincidence", "In the case of various conditions and assumptions, what time window is needed before and after and the number of participants is the fundamental reason why the earth cannot be replicated" "Premise 1: appropriate time" "With comet, a substance that provides a large amount of coolant, it is not enough, and many conditions need to be met."
First of all, the formation of the earth's crust requires that the earth is still in the early stages of formation, when the earth's crust has not yet formed.Otherwise, the earth's crust has already formed on the earth.At this time, no amount of water to cool down is useless, it will only increase the thickness of the earth's crust, making the earth even colder.Secondly, that period cannot be too early.If it is too early, the temperature of the earth will be too high, and a large amount of seawater will be vaporized into space. ”"So, we say that the curing of the earth's surface needs to be done in an appropriate period of time, not earlier, not later.""
It's a very demanding and very necessary condition.""
Premise 2: The right amount of water" "The amount of water is also a very important condition.If there is too much water, the earth may be enveloped by water, and it is impossible to expose the land at all, similar to Europa, there can be no less water, and if it is less, it will not form a rock layer of sufficient thickness, or even be completely vaporized, and the high temperature inside the earth can also smoothly reach the surface of the earth, maintaining thermal radiation to the universe, and cannot become the current earth. ”"Some people will say: this is impossible for the comet we know to be so big," "how big can a comet really be," "let's see how much sea water there is." ”"There are about 1.3 billion cubic meters of water on Earth, and if the volume of seawater is the volume of a comet, the diameter of this sphere is about 10 times that of an ordinary large comet, and the volume of a common comet over 1000k is usually between 10k00k.And the diameter of our earth satellite moon is "", from which it can be seen that the volume of seawater is still much smaller than the volume of the moon. ”To be continued.If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation
