While the immense pressure should keep iron and nickel solid, the temperature gradient in this region is so extreme that it overcomes the pressure, creating a churning, molten sea. Temperature: At the core, temperatures are estimated to reach a staggering 5,000 to 6,000 degrees Celsius, rivaling the surface of the Sun.
Seismic Waves Decoding Earth's Internal Structure and Hidden Layers
When tectonic plates grind against each other or release stored energy, they generate seismic waves that propagate through the planet like the ripples from a stone dropped in a pond. By meticulously recording these waves on a global network of seismographs, researchers can decipher the planet's internal structure.
The journey to the Earth core represents one of humanity’s most profound scientific ambitions, a quest to penetrate the planet’s innermost sanctuary and unravel the secrets of our planetary engine. This fluid motion is not merely a curiosity; it is the engine of our planet's magnetic field.
Seismic Waves Decoding Earth's Internal Structure and Hidden Layers
Key discontinuities, such as the Mohorovičić discontinuity (the crust-mantle boundary) and the Gutenberg discontinuity (marking the core-mantle boundary), were identified through these seismic patterns, revealing a stratified Earth long before any direct sample was ever seen. This immense weight would crush any conceivable vessel into its constituent atoms long before the destination was reached.
