Grassfield HS Plate Tectonics Review

The result of an active transform tectonic boundary 

This crustal boundary collision causes one crustal plate to be subducted below the other

How many types of tectonic plates are there?  

When a continental plate collides with another continental plate this feature forms

Which is not a type of volcano

Tectonic Plates are moved by these currents in the Asthenosphere

The folded mountain range that was created when Africa and N. America collided 

The thickest part a continental plate is  

The core is a solid layer of the Earth.  it is made mostly of the elements  

A volcanic mountain range in South America that borders an active convergent boundary 

Plate boundaries that have a lot of tectonic activity are called 

This dinosaur fossil has been found on several continents (an evidence of continental drift) 

The largest volcanoes and the most violent  

On the seafloor younger crust is near the _______ and older crust is nearest the ___________. 

The deepest place on the planet is 

When a divergent boundary exists between two continental plates this feature forms? 

This man proposed the theory of Continental Drift  

This boundary causes plates to slip or slide past each other sometimes causing earthquakes

The largest tectonic plate is the 

Harry Hess used this technology to find the Mid Atlantic Ridge

The naval officer pictured here, located the Mid Atlantic Ridge

A part of the Earth that contains the crust down to bottom of the rigid upper upper mantle.

Roughly how long ago did Pangea exist?   

Most Volcanic Activity and Earthquakes generally happen along what locations

Name of the the supercontinent that was once home to all continents? 

The type of igneous Rock found under Oceanic Plates

The highest parts of the Atlantic Ocean 

The boundary shown below is  

Oceanic crust is mafic,  _________ and more _________ than thick, felsic Continental Crust

Which volcano is long and generally low.  Found on the Hawaiian Islands.
