What are the layers of the Earth and their characteristics?
Understand the Problem
The question is focused on understanding the different layers of the Earth and their characteristics. It aims to convey information about the Earth's structure and the properties of each layer.
Answer
Crust, mantle, outer core, inner core.
The Earth is composed of four main layers: the crust, mantle, outer core, and inner core. The crust is the outermost solid layer, the mantle is semi-solid rock, the outer core is liquid iron and nickel, and the inner core is solid iron and nickel.
Answer for screen readers
The Earth is composed of four main layers: the crust, mantle, outer core, and inner core. The crust is the outermost solid layer, the mantle is semi-solid rock, the outer core is liquid iron and nickel, and the inner core is solid iron and nickel.
More Information
Earth's layers are distinguished by their physical and chemical properties. The crust is thin and solid, the mantle is mostly solid with slow movement, the outer core is liquid, and the inner core is the densest and hottest layer.
Tips
A common mistake is confusing the mantle's semi-solid state with a completely solid state. The mantle behaves plastically, allowing for slow convective movements.
