Understanding Subduction Zones

What is the primary characteristic of a convergent plate boundary?

• Plates remain stationary

• Plates move away from each other

• Plates slide past each other

• Plates move towards each other

Which type of crust is more likely to subduct under another?

• Neither crust subducts

• Continental crust

• Oceanic crust

• Both crusts subduct equally

What geological feature is commonly formed at a subduction zone?

• Plains

• Oceanic trenches

• Deserts

• Mountain ranges

What happens to the subducting plate as it moves deeper into the Earth?

• It remains unchanged

• It melts and forms magma

• It becomes colder

• It rises back to the surface

Which natural disaster is directly caused by underwater earthquakes at subduction zones?

• Hurricanes

• Tsunamis

• Droughts

• Tornadoes

What is a common result of pressure build-up at a subduction zone?

• Landslides

• Earthquakes

• Volcanic eruptions

• Floods

Which mountain range is an example of a subduction zone?

• Alps

• Andes

• Himalayas

• Rockies

What is the primary difference between subduction involving oceanic-continental and oceanic-oceanic crusts?

• The type of crust that subducts

• The absence of trenches

• The formation of volcanic islands

• The presence of earthquakes

What is the result of volcanic activity at oceanic-oceanic subduction zones?

• Expansion of plains

• Development of deserts

• Creation of volcanic islands

• Formation of mountain ranges

Which plate is typically older and more dense in an oceanic-oceanic subduction scenario?

• The younger plate

• Neither plate is dense

• The older plate

• Both plates are equally dense
