convergent boundaries are where two lithospheric plates move together (collide) and the more dense plate sinks under the less dense plate. define subduction zone.

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

The collision between two plates that are moving towards each other is called a convergent boundary. When two continental plates converge the result is the formation of large folded mountains. The classic example is the collision between the Indian plate and the Asia plate. The result is the Himalayan mountains.

When two plates move towards each other, the boundary is known as a convergent boundary. When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone.

The newest, thinnest crust on Earth is located near the center of mid-ocean ridge—the actual site of seafloor spreading. The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge.
