Earth's Mechanical Layers

The central or inner most part of the earth, made of 2 layers.  

• Mantle 
• Crust
• Core

What two layers make up the core?  

• Mesosphere and 
  Asthenosphere 
• Inner and Outer core
• Lithosphere and Outer Core
• Inner core and Mesosphere

Middle part of the mantle that is partially molten rock, or putty like, or semisolid.

• Asthenosphere
• Mesosphere
• Lithosphere
• Crust

Made of mostly iron and nickel.

• Mantle and crust
• Mantle and core
• Inner core and outer core
• Crust only

Outer most layer of the earth.

• Core
• Mantle 
• Crust

Thin layer that has two layer called oceanic and continental.  

• Crust
• Core
• Mantle
• Atmosphere

Includes the crust and upper mantle that is divided into several constant moving plates of solid rock that floats on the layer below it. 

• Asthenosphere 
• Mesosphere
• Lithosphere 
• Crust

A cold rigid layer or brittle layer located on the outside. 

• Inner core
• Outer core 
• Crust 
• Lithosphere

The inner most layer is ...

• hot, metallic liquid
• hot, metallic solid
• cold, brittle
• cold, molten

Thickest layer of the Earth that is mostly solid, except for the semi solid upper part. Made of three mechanical layers.

• Mantle
• Crust 
• Core
