Ever wondered how scientists know so much about Earth's interior, even though we can't directly observe it? The answer lies in understanding seismic shadow zones. This video breaks down the fascinating process behind their formation and what they reveal about our planet's hidden layers.

In this explanation, you'll learn:
► How different types of seismic waves (P and S waves) behave as they travel through Earth's diverse layers.
► The role of refraction and reflection at core-mantle boundaries in creating areas where waves can't be detected.
► Why S-waves have a larger shadow zone compared to P-waves, and what this tells us about the outer core's composition.
► How analyzing these shadow zones provides crucial evidence for the existence and properties of Earth's liquid outer core.
