2.1.1 The 4 Tectonic Plate Boundaries and the Hazards

Along the edges of the tectonic plates, (a)   .

• The real action happens
• Plates remain static
• Plates dissolve
• Nothing significant

What are plate boundaries sometimes also called? (a)  

• Plate cores
• Plate centers
• Plate margins
• Plate edges

Match the following plate boundaries with the correct description of magma activity.

• Boundaries that do not exist in plate tectonics

• Convergent plate boundaries

• Boundaries where magma is rising up in the mantle below

• Divergent plate boundaries

• Boundaries where plates move towards each other, potentially causing volcanic activity

• Static plate boundaries

• Boundaries where plates slide past each other without creating or destroying lithosphere

• Transform plate boundaries

Where do divergent plate boundaries mostly appear?

• Near river deltas

• In the middle of continents

• On mountain tops

• At the bottom of the sea

What natural hazard is commonly found at constructive boundaries?

• Volcanoes

• Tsunamis

• Hurricanes

• Tornadoes

What happens to the oceanic plate when it moves towards a continental plate?

• It is forced underneath

• It floats above

• It disintegrates

• It remains static

What is created when two continental plates crash head-on?

• Mountains

• Lakes

• Valleys

• Islands

What type of boundary occurs where tectonic plates are sliding past each other?

• Convergent boundaries

• Transform boundaries

• Divergent boundaries

• Static boundaries

Why don't volcanoes occur at collision boundaries?

• The temperature is too low

• Too much water

• No magma rising up underneath

• The pressure is not enough

What causes earthquakes at conservative boundaries? (a)  

• The plates get stuck and then jump
• Magma explosions
• Rapid plate creation
• Sudden temperature changes
