Plate Tectonics Quiz

Which statement best defines a "subduction zone"?

• A region where two plates slide past each other without creating landforms

• A deep trench formed by erosion at continental margins

• A process where one tectonic plate sinks beneath another into the mantle

• An underwater mountain chain formed by diverging plates

Which of the following are the three main types of plate boundaries?

• Normal, reverse, strike-slip

• Volcanic, seismic, and oceanic

• Convergent, divergent, transform

• Subduction, trench, ridge

What best describes the movement at a divergent plate boundary?

• Plates collide, and one slides beneath the other

• Plates grind past each other horizontally

• Plates pull away from each other, creating new crust

• Plates remain stationary but push upward

What combination of features is most likely to be found at a convergent boundary between an oceanic and continental plate?

• Rift valley, new crust, volcanoes

• Trench, subduction zone, volcanic arc

• Mid-ocean ridge, magma rise, basalt crust

• Fault line, crustal cracking, shallow focus earthquakes

Which landforms are commonly formed at each type of plate boundary?

• Mountains at divergent, trenches at transform, and ridges at convergent

• Trenches at divergent, island arcs at transform, and faults at convergent

• Mid-ocean ridges at divergent, volcanic arcs at convergent, and fault lines at transform

• Fold mountains at divergent, volcanic arcs at transform, and ridges at convergent

Which of the following best defines transform plate boundaries?

• Plates move away from each other

• Plates collide with each other

• Plates slide past each other horizontally

• Plates fold and form mountain ranges

The Philippines is officially recognized as having 7,641 islands. From which type of plate convergence did many parts of the Philippine Archipelago originate?

• Continental-Continental

• Continental-Oceanic

• Oceanic-Oceanic

• Oceanic-Transform

Why are volcanoes and earthquakes common at convergent plate boundaries?

• Because plates slide past one another without pressure

• Because plates pull apart and form mid-ocean ridges

• Because land remains stable during plate interaction

• Because one plate subducts under another, creating magma and pressure buildup

Which landform is most likely formed at a divergent boundary?

• Volcanic island arc

• Mid-ocean ridge

• Ocean trench

• Fold mountain

A scientist observes a deep trench and volcanic arc near a subduction zone. Which plate boundary is involved, and what processes are occurring?

• Passive boundary; plates are stationary, causing minor activity

• Transform boundary; plates are grinding past each other, forming ridges

• Divergent boundary; plates are moving apart, forming new crust

• Convergent boundary; one plate is sinking beneath another, forming volcanoes and trenches
