Rocks and Layers of the Earth

Which layer of Earth do scientists believe is most likely made of solid metals?

• crust
• outer core
• inner core
• mantel

 Which layer of Earth is the thinnest? 

• crust
• outer core
• mantle
• inner core

Which letter in the diagram identifies the layer scientists believe to be in a liquid state?

• Location A
• Location B
• Location C
• Location D

Where in the diagram might you expect to find rocks of the lowest density?

• Location A
• Location B
• Location C
• Location D

Which of the following events led to the formation of the layers of Earth?

• A slow deposition
  
• A constant cooling
• A large impact
• A spinning rotation
  

Which layer of Earth is composed of liquid rock? 

• crust
• lithosphere
• inner core
• outer core

Which is the best description of the characteristics of the asthenosphere?

• Solid , but flowing
• Hot, but solid metal
• Liquid, but dense
• Brittle, but shifting

The lithosphere is composed of rock that can be described as being

• Pressure would change from very high to none
• Density would change from least to most dense
• Plasticity would change from flexible to rigid
• Heat would change from relatively hot to cool

Which of the following describes a change in moving from Earth’s crust to the outer core?

• Pressure would change from very high to none
• Density would change from least to most dense
• Plasticity would change from flexible to rigid
• Heat would change from relatively hot to cool

The lithosphere consists of the 

• upper mantle and the crust
• lower mantle and the outer core
• inner and outer core
• crust and the entire mantle
