One could even theorize that the enormous weight of all the soil and rock of the layers of the earth would create such great friction that a tremendous amount of heat would be the result. Melting all the matter of the earth's core. The eruption of a volcano could be evidence of this "melted earth" eventually spewing to the surface, once the built up steam and pressure of this phenomenon is finally released.
They do not have evidence. In fact most pf things are not even true. The only thing they say they did was put a stick on the ground and with a shockwave they knew what was inside the earth. My opinion is that the core is not what scientists say it is. Due to the fact that we know more about the moon than our own planet.
Based on the physical properties of the earth;The core is divided into outer core and inner core.the liquid layer of the earth core is the outer core,while the inner core is solid.
The core is in the center of the Earth.
Actually, no. But if something falls into the earth's core, and it is very heavy, like lets say for example: If a Building falls into the earths core, then the whole earth will erupt, causing the earth's core to rotate, then the earth's core will be unstable and the whole world will erupt.
The earth's core principal ingredient is magma.
Magnets were attracted to the cor of earth.
there are convection currents in the upper core.
Tidal heating supports the dynamo theory. Magnetized lunar rocks and asteroids are used for evidence of this.http://phys.org/news/2012-10-evidence-dynamo-asteroid.htmlEarth's outer core contains liquids that conduct electricity.Earth's outer core is a liquid. Earth's core contains mostly iron and nickel.
The temp has been shown to rise by temps observed in very deep mines. The theory behind the conclusion is that the Earth is still undergoing cooling, and consists of a molten core, of liquid rock called 'magma'...which is seen rising to the surface thru volcanos.
The effect that Earth's gravity has on other planets and the sun can be calculated. This degree of gravity that is demonstrated points to a heavy core that is metal. Fragments of nickel-iron meteorites that are remnants of planetary collisions also indicate that other planets have a nickel-iron core.
Seismic wave behavior provided the key evidence for the iron composition of Earth's inner core. The way seismic waves travel through the core suggests it is solid and made mostly of iron, due to how iron behaves under high pressure and temperature conditions. This information is corroborated by studies of meteorites and high-pressure experiments that simulate the conditions of Earth's core.
One piece of evidence is that seismic waves pass through the Earth's core, indicating that it is not a solid mass. Additionally, the Earth's magnetic field is believed to be generated by the movement of molten iron within the outer core. Lastly, experiments conducted in labs using high-pressure and high-temperature conditions have simulated the Earth's core and showed that it behaves as a liquid.
Scientists infer that the Earth's core is made of a different material from seismic waves generated by earthquakes. The behavior of these waves as they travel through the Earth's interior suggests that the core is composed of iron and nickel, based on its density and the way the waves travel through it. Additionally, the behavior of magnetic fields around the Earth supports this conclusion.
One piece of evidence for the Earth's central core being solid comes from seismic waves that travel through the Earth. S-waves are unable to travel through liquid, so their absence in the Earth's core suggests it is solid. Additionally, studies of the Earth's magnetic field and how it behaves support the idea of a solid inner core.
Evidence supporting the idea that Earth's core is composed of an iron-nickel alloy includes seismic studies showing that the outer core is liquid and has lower density than the inner core, which is solid and denser. Additionally, the Earth's magnetic field, generated by the movement of molten iron and nickel in the outer core, aligns with this composition. During Earth's formation, heavier elements like iron and nickel sank to the center due to their high density, a process known as planetary differentiation, which resulted in the formation of the core.
Rock found on the moon is similar to rock found on the earth. The earth also has a relatively large iron core whereas the moon has a much smaller one. The earth is also on an axis, which is a result of it's impact with the moon.
Indirect evidence from Seismic Waves, and direct evidence from rock samples.
