Earth's Surface and Plate Tectonics

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 coolest layer

• crust
• inner core
• mantle
• outer core

The thinest layer

• crust
• inner core
• mantle
• outer core

Where 2 plates are moving together

• Divergent Boundary
• Convergent Boundary 
• Transform Boundary 

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

The process for new oceanic lithosphere forming at mid ocean ridges

• Continental Drift
• Seafloor Spreading
• Plate Tectonics
• Pangaea

Ocean trenches always form at subduction zones where dense oceanic crust subducts.

• True
• False

Volcanoes never form along subduction zones.
