Earth's Interior Layers Quiz

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
