Here's a breakdown:

* Lithospheric plates: The Earth's outer layer (the lithosphere) is broken into these large, rigid plates.

* Subduction: One plate (the denser one) slides beneath the other, sinking into the Earth's mantle.

* Consequences: Subduction zones are associated with many geological features, including:

* Volcanoes: Molten rock (magma) from the melting plate rises to the surface, forming volcanoes.

* Earthquakes: The movement of the plates along the subduction zone causes earthquakes.

* Deep ocean trenches: The bending of the upper plate creates a deep depression in the ocean floor.
