Plate Tectonics Review

Plate movement is caused by _______________________________.

• the rotation of the Earth
• Earth's magnetic field
• convection currents in the mantle
• continental drift

What would you be most likely to find at a divergent boundary between two pieces of oceanic crust?

• Deep Ocean Trench
• Mid-Ocean Ridge
• Hot Spot
• Island Arc

A weak spot in the crust where magma has come to the surface is called a

• volcano
• deep-ocean trench
• mountain
• lava

• Deep-Ocean Trench
• Mountains
• Rift Valley
• Island Arc

Name the boundaries in the order that they appear...

• transform, divergent, convergent
• divergent, convergent, transform
• divergent, transform, convergent
• convergent, divergent, transform

• Oceanic meets continental crust, where a TRENCH is formed.
• This is a convergent boundary, where earthquakes and rift valleys form
• The is a divergent boundary, where volcanoes and mountain ranges form
• This is a transform boundary, where earthquakes happen

A chain of underwater mountains is called a

• Mountain
• Rift valley
• Deep-Ocean trench
• Mid-Ocean Ridge

The OLDEST seafloor is located? 

• Closest to the mid-ocean ridge
• Farthest from the mid-ocean ridge

The most dense seafloor is located? 

• Closest to the mid-ocean ridge
• Farthest from the mid-ocean ridge

The COOLEST rock on the seafloor is located? 

• Closest to the mid-ocean ridge
• Farthest from the mid-ocean ridge
