Satisfactory answero( o Level 62010-11-29The temperature and pressure in the Earth's interior are so high that the rocks inside melt into magma! Follow-up: Why is there pressure and why is there temperature:
The magnetic field strength of the earth's core is very large, so that the object inside is unstable in structure, heated, and temperature rises on the basis of strong magnetic resonance, and finally melts, and after becoming a fluid, it moves directionally under the action of the magnetic field, further strengthening the magnetic field strength, and constantly circulating! Follow-up: Why hasn't the earth melted yet?
Since the inner core of the earth is a series of conductive fluids for directional motion, by modern physics, this layer of fluid forms a circulation, so that there is an electromagnetic shield, that is, the magnetic field at the core is very large, and the magnetic field outside the core is sharply reduced! In addition, due to the special stratigraphic structure of the earth, the external effect of the internal magnetic field is almost zero!
This explains your suspicion, in fact, it is the existence of this gyrome that naturally puts the earth in a kind of equilibrium: a huge flow of energy inside, and calm and harmony outside! At the same time, because of this layer of circulation, scientists have not been able to use effective equipment to explore the condition of the inner core, because the detection of the external requires high sensitivity, and entering the inner core, it must withstand a huge electromagnetic field!
This is still a problem for the world!

Mars is known to be a typical terrestrial planet, so Mars has long been considered by scientists to be one of the most likely planets for extraterrestrial life. But the reality is that the surface of Mars is full of desert sand dunes, and there are frequent dust storms all year round. It can be said that the environment is very harsh.

The temperature and pressure in the Earth's interior is so high that the rocks inside melt into magma!

In geology, there is no magma.
The concept of layers is just trembling in the earth's crust and mantle.
In between, there is an asthenosphere, which is recognized as the birthplace of magma.
The asthenosphere, also known as the asthenosphere, is located below the upper lithosphere of the upper mantle at depths of 80-400 kilometers. The top-bottom interface of the asthenosphere is not very certain, and there is no open and void closed interface between the asthenosphere and the lithosphere, which has the characteristics of gradual transition.
The formation of the asthenosphere is a long geological evolutionary process. Asthenospheric lava is produced by the need for heat, water and volatile substances, mainly from radioactive elements deep underground.
Decay and the Earthsphere.
The differentiation process is released. When the released heat energy and light components rise to the bottom of the low-temperature and hard lithosphere, they are blocked by the lithosphere and gradually accumulate, resulting in the eventual formation of the asthenosphere, so the formation of the asthenosphere is the product of the development of the earth to a certain stage of bucket cave cracking.
The asthenosphere is generally considered to be the main source of magma.
-
Of course, the earth has a magma layer of acacia magma, and it is very thick, but the earth's magma layer is not called a magma layer called a mantle, the earth's crust is under the mantle, and inside the mantle is a large amount of hot lava. The center of the feast and laughter is the core of the earth.
-
The Earth does not have a layer of magma. In geology, there is no such thing as a magmatic layer, just an asthenosphere between the earth's crust and mantle.
-
There must be, when the temperature reaches a certain condition, and somewhere on the earth is not so hard, it will turn into magma.
-
The earth has three layers: the crust, the (i.e., the lithosphere), the mantle, and the core. The rock is trapped in the lower part of the crust, the next layer of the lithosphere, in the upper layer of the mantle, that is, between the crust and the mantle.
-
Yes, about 90,000 kilometers inside.
-
Magma in the Earth's mantle layer.
The magma is located underneath the earth's crust, the lithosphere.
The next layer is in the upper layer of the mantle, that is, between the crust and the mantle. Magma is a high-temperature, complex silicate salt deep in the earth's mantle.
Melt. The physical properties of this cavity melt.
It's special, it's like a hard solid and a soft liquid.
Causes of magma formation
There are two main types of magmatic rocks: intrusion and ejection. Rocks formed by the slow cooling of magma at a certain depth of the earth's crust are called intrusive rocks. It takes a long time for intrusive rocks to consolidate into rocks.
Geologists have estimated that it will take about 64,000 years for a 2,000-meter-thick granite body to fully crystallize; Rocks formed by magma erupting or overflowing to the surface and condensing are called ejecta rocks. Due to the rapid accumulation and decrease of magma temperature, the time of consolidation and diagenesis of the ejecta rock is relatively short. 1 meter thick basalt.
It takes 12 days to crystallize, 3 years for 10 meters thick, and 9,000 years for 700 meters thick. It can be seen that the time required for intrusive rocks to consolidate is much longer than that of ejecta rocks.

The earth has the earth's crust, (i.e. lithosphere) mantle, the core.
These three layers. Magma.
At the lower end of the crust, that is, under the lithosphere, and in the upper layer of the mantle, between the crust and the mantle. Magma is a hot, complex silicate deep in the earth's mantle.
Melt. The physical properties of this melt are peculiar, it resembles both a hard solid and a soft liquid.
The Earth is one of the nine planets of the solar system.
One of them, millions of kilometers away from the Sun. It has a diameter of 12,756 km; The density is Woola Duang cubic centimeters. The Earth has only one natural satellite, the Moon.
The shape of the Earth is an ellipsoid, slightly uplifted at the equator, slightly flattened poles, and the radius of the equator is more than 20 kilometers longer than the radius of the pole. The Arctic region is about a meter higher than the Antarctic region.
Lowered to the next meter, it is shaped like a large duck pear lying upside down. Actually, these irregular parts of the earth are insignificant to the earth. Judging from the Earth** photographed by an artificial earth satellite, it is more like a standard round ball.
The rotation of the Earth. The direction is from west to east, and it revolves around the sun at the same time. The combination of the Earth's rotation and its orbital motion produces the alternation of day and night and the changing seasons on Earth.
The speed at which the Earth rotates is uneven. At the same time, due to the gravitational effects of the sun, moon and planets, as well as the various effects of the atmosphere, oceans and internal materials of the earth, the direction of the earth's axis of rotation in space and the earth itself must change. The inertial centrifugal force generated by the rotation of the earth causes the spherical earth to gradually expand from the poles to the equator, becoming the current slightly flattened spheroid.

Upper mantle layer and deep into the earth's crust.
Primary magma is formed from molten material trapped by the Earth's core. The earth's core captures molten matter, rents ballast, and some other substances, forming a huge thick molten layer. The composition of these substances is uneven. The primary magma solidified to form the most primitive earth's crust.
The various intrusive rocks we see, such as ultramafic rocks, mafic rocks, neutral rocks, acidic rocks and alkaline rocks, as well as all kinds of magma erupted by volcanoes, are all regenerated magma, but the depth of the channel is different and the degree of differentiation is different. The Earth's core traps molten material and some other materials to form a huge thick molten layer. Digging and excavating.

Human beings have to find a way for themselves, because the earth is a starting point for human beings to go farther after all, because the previous generations of life on the earth have proved that the earth will not allow a creature to exist forever, and it must be changed, so we have only just entered space for decades and continue to explore which planet can be a suitable habitable planet for human beingsBecause life on Earth seems to be unable to escape the end of destruction in the end, because 5 generations of life have proven it before.

This is because the earth used to be a sphere of magma, but after billions of years of changes, its surface slowly cooled, forming the home we live in today, and the magma inside it still exists and has not cooled, so the internal environment of the earth is magma.
-
Because the earth evolved through the cosmic explosion, at first it was magma that slowly absorbed matter, forming the earth and various planets, so the internal environment of the earth is all magma.
-
Because the earth was a fireball in the beginning, not only was there magma inside, but also magma outside, and after many years, the surface of the earth cooled down before it was suitable for human habitation.
As we all know, the earth has undergone many geological activities since its inception, and the eruption of volcanoes has made us understand that the interior of the earth is hot。After geologists surveyed, we also know that under the land we walk, not only is there hot magma flowing, but also a large amount of radioactive elements that are decaying. >>>More
Because the vertical stability of the earth's gravity is generally recognized in our daily life, the earth's natural force, that is, the earth's gravity, is commonly known as the "earth's fixed gravity" (also to distinguish particle microgravity). The theory of studying the meaning, function, laws and characteristics of "the earth's natural force, that is, the earth's fixed gravity", is the "earth's fixed gravity", referred to as "the earth's gravity", which is the earth's natural force generated by the earth's material mass as a whole, that is, the earth's gravity, which occurs in and to the center of the sphere, also known as the spherical gravity. The natural force of the earth, that is, the energy of the earth's body (earth) and the earth's outer space (sky) reached by the earth's gravitational force, condenses in the direction of the earth's core, and this cohesion is carried out in a vertical downward way to stabilize the energy of the things it reaches. >>>More
Because the earth itself is tilted, the globe.
This is also made to conform to the reality and facilitate people's understanding of geographical knowledge. There is an angle between the Earth's orbit and the Earth's orbit, and this angle is calledYellow and red cornersIt has important astronomical and geographical significance, and is also the fundamental reason for the division of the four seasons and five zones on the earth. >>>More
Mars really resembles Earth! Mars orbits its axis every 24 hours, which is not much different from the Earth's rotation period. It should be that the tilt of the axis is about the same as that of the Earth, so there are also seasonal changes on Mars. >>>More
It's just that the diameter of the earth is relatively large, so people can't feel the arc, and if you get to a high enough height or leave the earth, you can feel the arc.
