layers of the earth

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

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

• Mantle
• Crust 
• Core

Which of the following is true regarding the composition of the lithosphere?

• The lithosphere is mostly liquid, with some medium-density materials, such as silicon.

• The lithosphere is more plastic and flows slowly compared to the solid crust of Earth.

• The lithosphere includes the core and the lower portion of the mantle.

• The lithosphere includes the crust and the uppermost portion of the mantle, which is solid and rigid.

The layers of Earth are the crust, mantle, and core, with the core being divided into inner and outer layers. Which of the following does NOT describe the layers of the Earth?

• The inner core makes up the majority of Earth's mass.

• The mantle is composed of molten rock.

• The core is made up of dense elements, such as iron and nickel

• The crust is extremely thin when compared to the core or mantle.
