Plate Tectonic

The completely liquid layer of Earth is called the...

• outer core
• inner core
• mantle
• crust

What is the cause of all crustal activity?

• magnetic-pole reversals
• faults in mountain ranges
• energy from the sun
• convection current in the mantle

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• subducting

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• submergent

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• strike slip

What geologic feature/event you be most likely to find at a transform boundary?

• Earthquakes
• Volcanoes
• Mountains
• Rift Valleys

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of oceanic crust?

• Rift Valley
• Mid-Ocean Ridge
• Island Arc
• Flat land

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of continental crust?

• Mid-Ocean Ridge
• Mountain
• Rift Valley
• Island Arc

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

Convection currents in the Earth's mantle are caused by

• Less dense hot magma moving downward
• Less dense hot magma moving upward
• Tectonic plate movement
• More dense cooler magma moving upward
