Study Notes
Earth's Interior Layers
- Earth's interior is layered
- The diagram shows the layers of Earth, from outermost to innermost: crust, mantle, outer core, inner core
- The crust is the outermost and thinnest layer
- The mantle is the thickest layer, and composed of solid rock
- The outer core is a liquid layer, made of mostly iron and nickel
- The inner core is a solid sphere, made mostly of iron and nickel. It is the hottest and densest part of Earth.
- The inner core is solid due to intense pressure
- The outer core is liquid due to lower pressure
- The composition of each layer, from outermost to innermost is: rock, mostly solid rock, mostly iron and nickel, mostly iron and nickel
- The state of each layer from outermost to innermost is: solid, solid, liquid, solid
Comparing Layers
- The densest layer is the inner core
- The least dense layer is the crust
- The hottest layer is the inner core
- The coldest layer is the crust
