Plate Tectonics Practice

This layer is a mix between solid and liquid

• crust
• inner core
• mantle
• outer core

The most dense layer

• crust
• inner core
• mantle
• outer core

What two specific continents fit together most noticeably?

• Africa and North America
• South America and Europe
• South America and Africa
• Antartica and Africa

undersea mountain ranges containing steep narrow valleys.  New ocean floor is formed here.

• Mid-ocean Ridge
• Applachian Mountains
  Appalachian Mountains
• Pacific spreading belt
• sea floor spreading

What direction do plates move at a transform boundary?

• toward each other
• away from each other
• slide past each other

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries

Where does the heat come from that drives this convection current in the mantle? 

• The sun
• The crust
• the mantle
• the core

The tectonic plates float on the 

• lithosphere
• lower mantle
• outer core
• asthenosphere

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary
