Unit 5 Plate Tectonics Test LIFT

The part of the earth that includes the crust and the upper mantle and is split into tectonic plates is the

• lithosphere
•  crust
• asthenosphere
• mantle

The hottest layer

• crust
• inner core
• mantle
• outer core

The thinest layer

• crust
• inner core
• mantle
• outer core

The thickest layer

• crust
• inner core
• mantle
• outer core

This layer is completely liquid

• crust
• inner core
• mantle
• outer core

This layer is completely solid due to the intense pressure it is under

• crust
• inner core
• mantle
• outer core

This layer is solid

• asthenosphere
• mantle
• outer core

The theory stating the continents were once joined in a large mass that broke apart.
