Plate Boundaries

Do subduction zones have volcanoes?

• True, subduction zones often have volcanoes due to the melting of the subducted plate.

• No, subduction zones do not have volcanoes.

• Yes, but only in oceanic regions.

• Subduction zones have volcanoes only when tectonic plates collide.

What is a transform boundary?

• A type of boundary where tectonic plates collide.

• A boundary where tectonic plates slide past each other.

• A boundary that forms when tectonic plates pull apart.

• A boundary that is characterized by volcanic activity.

What kind of plate boundary is formed when two plates collide?

• A divergent boundary

• A transform boundary

• A convergent boundary

• A lateral boundary

What type of boundary is associated with the formation of mountains?

• Divergent boundaries

• Transform boundaries

• Convergent boundaries

• Lateral boundaries

What is the role of magma in subduction zones?

• Magma cools and solidifies underground, forming new rock layers.

• Magma rises to the surface in subduction zones, often resulting in volcanic eruptions.

• Magma is expelled into the atmosphere, causing climate change.

• Magma remains stagnant and does not affect the surrounding geology.

What is the stress in convergent boundaries called?

• Tension

• Shear

• Compression

• Bending

What is subduction?

• A process where two tectonic plates collide and create mountains.

• A process where one tectonic plate moves under another and sinks into the mantle.

• A method of measuring tectonic plate movement over time.

• A phenomenon that occurs when tectonic plates slide past each other.

What is the main feature of a transform boundary?

• Vertical movement of plates away from one another.

• Horizontal movement of plates past one another.

• Formation of new crust at the boundary.

• Subduction of one plate beneath another.

What is the difference between oceanic and continental plates?

• Oceanic plates are thicker and less dense than continental plates.

• Oceanic plates are denser and thinner than continental plates.

• Continental plates are denser and thinner than oceanic plates.

• Oceanic plates and continental plates are identical in density and thickness.

What is a divergent boundary?

• A boundary where tectonic plates collide and create mountains.

• A boundary where tectonic plates move apart, often leading to the formation of new oceanic crust.

• A boundary that remains stationary while surrounding plates move.

• A boundary where tectonic plates slide past each other, causing earthquakes.
