Understanding Plate Boundaries

The video explains tectonic plates and their interactions at plate boundaries. It covers three main types of boundaries: convergent, divergent, and transform. Convergent boundaries occur when plates collide, potentially causing one to slide under the other. Divergent boundaries form when plates move apart, leading to phenomena like seafloor spreading, where new sea floor is created as molten rock fills the gap. The video uses sponges as a model to illustrate these concepts.

What is the term used for the area where two tectonic plates meet?

• Plate boundary

• Volcanic arc

• Seismic zone

• Fault line

Which type of boundary is formed when tectonic plates collide?

• Divergent boundary

• Subduction zone

• Convergent boundary

What can occur when two tectonic plates collide?

• They push one another up or slide under each other

• They cause a tsunami

• They create a volcanic island

• They form a new ocean
