Why Does The Earth Have Layers?

Have you ever wondered what is actually hidden miles beneath your feet? In this video, we answer the ultimate geological question: Why does the Earth have layers? We travel back 4.5 billion years to explain how a molten young Earth separated into distinct zones based on density through a process called differentiation. We break down the simple science behind all four major layers, exploring the thin rocky crust, the massive churning mantle, the liquid metallic outer core, and the intensely pressurized, solid inner core. #science #scienceinahurry #stem #geology #earthscience #earth #space #astronomy #nature #education
