Why Does The Earth Have Layers?

The video explains how Earth's structure is determined by layers of varying density, which we study through seismic activity. It traces the formation of elements in the universe, leading to planet creation. The Earth's core is discussed, highlighting the role of seismic waves in understanding its composition. The video also covers Earth's magnetic field, generated by the liquid outer core, and the planet's gradual cooling process.

What role do seismic waves play in understanding the Earth's inner structure?

Discuss the impact of Earth's cooling on its outer core and atmosphere.
