Which deductive reasoning provides enough contradicting the idea that earth's core is solid
The deductive reasoning that provides enough contradiction to the idea that the Earth's core is solid is seismological evidence.
Seismological evidence comes from the study of seismic waves, which are generated by earthquakes and other sources. These waves travel through the different layers of the Earth and can be detected and recorded by seismographs.
Researchers have found that seismic waves travel differently through the Earth's core compared to other layers, such as the mantle. These waves can be divided into primary (P) waves and secondary (S) waves, which behave differently depending on the physical state of the material they pass through.
Through seismological analysis, scientists have observed that S-waves cannot travel through the Earth's core, indicating that the core must be in a liquid or molten state. This is because S-waves are shear waves that require a solid medium to propagate, and the absence of S-waves in the core suggests a fluid or molten material.
On the other hand, P-waves can travel through both solid and liquid materials, and they do travel through the Earth's core. However, the speed at which P-waves travel through the core is significantly slower than their speed in the surrounding mantle. This supports the hypothesis that the core is composed of a partially molten, viscous material.
Therefore, based on seismological evidence, the deductive reasoning contradicts the idea that the Earth's core is solid and suggests that it is primarily in a liquid or molten state with some solid components.
