Ever wondered what’s actually beneath our feet? 🌍 Earth isn’t solid all the way through — it’s made up of several massive layers stacked deep inside the planet. The outer layer is the crust, the thin shell where continents, oceans, cities, and all life exist. Compared to the rest of the planet, it’s incredibly thin. Below that lies the mantle, a huge layer of extremely hot rock that slowly moves over millions of years. These slow movements help drive tectonic plates across the surface, shaping mountains, oceans, and earthquakes. Deeper still is the outer core, a vast ocean of molten iron and nickel. This liquid metal constantly moves and swirls, generating Earth’s magnetic field — the invisible shield that protects the planet from harmful solar radiation. At the very centre sits the inner core, a solid sphere of iron and nickel under unimaginable pressure. Even though temperatures are similar to the surface of the Sun, the intense pressure keeps it solid. Together these layers fo...
