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.

Explain the process of seafloor spreading.

How fast are the plates at the Mid-Atlantic Ridge moving apart?
