Layers of the earth

• The 3 layers of the Earth are crust, mantle, and core
• Which layer of the Earth is pure liquid made of iron and nickel?

  Outer core
• The crust and the uppermost mantle make up the solid layer of hard rock called the lithosphere
• A is the crust. B is the Mantle. C is the outer core. D is the inner core

  
• Which layer of Earth is characterized by rock that is plastic, or soft enough to flow?

  Asthenosphere
• Which layer of the earth is made out of solid iron?

  Inner core
• Asthenosphere is the mechanically weak and semi-fluid layer
• Continental crust is less dense
• Oceanic crust is more dense
• What type of crust does not subduct?

  Continental
• Scientists determine what Earth’s interior looks like by using seismic waves
• This is the hottest layer of the Earth

  Inner core
• This layer contains most of Earth's mass.

  Mantle
• Oceanic Crust is mostly made of basalt
• Continental crust is mostly made of granite
• What is the outermost layer of the Earth?

  Crust
• What is the innermost layer of the Earth?

  Inner core
• Which layer of the earth consists of molten?

  Outer core
• Which layer lies directly above the outer core?

  Mantle
• What layers make up the Lithosphere?

  Crust and upper mantle
• Oceanic crust is younger and newer
• Continental crust is older and more buoyant
• Oceanic crust is constantly renewed and destroyed
• What is the name of the layer that exists in the mantle where convection occurs?

  Asthenosphere
• The outer core generates Earth's magnetic field
• Temperature and pressure of the outer core causes molten metal to move
• The boundary between the crust and mantle is called the Mohorovičić discontinuity
• Gutenberg discontinuity is what separates the mantle from the core
• Lehmann discontinuity is the boundary between inner and outer core
