4 Tectonic Plate Boundaries

What happens at constructive plate boundaries when magma rises to the surface?

• It leads to powerful earthquakes.

• It forms mountains.

• It creates new crust that moves apart.

• It causes plates to collide.

Which process occurs when an oceanic plate is forced beneath a continental plate at destructive boundaries?

• Sliding of plates past each other.

• Formation of bold mountains.

• Subduction due to the oceanic plate's higher density.

• Collision of plates with equal density.

What is the primary cause of earthquakes at destructive boundaries?

• Continental plates sliding gently past each other.

• Volcanic eruptions releasing pressure.

• Plates grinding and getting stuck on each other.

• Magma rising to the surface.

What distinguishes collision boundaries from other destructive boundaries?

• They involve oceanic plates sinking beneath continental plates.

• They form mountains without volcanic activity.

• They create new crust as plates move apart.

• They conserve the existing crust.

Why don't volcanoes form at conservative boundaries?

• The plates are being subducted beneath each other.

• The plates are colliding head-on.

• The plates are sliding past each other without magma rising.

• The plates are moving apart.
