Layers of the Earth

The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates “float” and move on this layer

• Exosphere
• Asthenosphere
• Mesosphere
• Thermosphere

The thin, solid, outermost layer of Earth; is either continental (landmasses) or oceanic (ocean floors)

• Earth's mantle
• Earth's core
• Earth's lithosphere
• Earth's crust

The cool, rigid, outermost layer of Earth that consists of the crust and the uppermost part of the mantle; broken into pieces or segments called plates

• Plateosphere
• Lithosphere
• Crustosphere
• Mantlecore

The solid layer of Earth between the crust and the core; made of dense silicates

• mantle
• lithosphere
• crust
• core

The outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron

• Inner core
• Mantle
• Crust
• Outer core

The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core

• Middle core
• Inner core
• Outer core
• Central core

A characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow

• Plasticity

• Liquid
• Solid
• Gas
