Understanding Earth's Layers
The Earth consists of several distinct layers, starting from the thin, brittle crust that we inhabit, which varies in thickness from about six kilometers beneath oceans to approximately 70 kilometers beneath continents. Beneath the crust lies the mantle, which behaves like a solid but flows slowly over long periods, akin to thick glass. The outer core consists of liquid iron, generating the Earth's magnetic field, while the inner core is solid, primarily made of iron and nickel. This layered structure impacts geological phenomena, including earthquakes and volcanic activity.
