Subduction

The video explains the interaction between tectonic plates, focusing on the collision between continental and oceanic plates. It describes the subduction process where the denser oceanic plate is pushed under the continental plate, leading to deformation and slow descent towards the mantle. This process often results in the formation of deep ocean trenches, such as the Marianas Trench, which is the deepest in the world.

What typically occurs when a continental plate meets an oceanic plate?

What happens to the oceanic plate when it collides with the continental plate?

How fast does the oceanic plate slide down towards the mantle?

What geological feature is often produced as a result of this collision?

Can you name the world's deepest ocean trench mentioned in the text?
