Earth's crust recycles itself at subduction zones
Earth's tectonic plates continuously recycle old crust at subduction zones, a vital process that shapes our planet and maintains its delicate balance.
Earth's outer shell is broken into massive plates that constantly move. At subduction zones, one dense plate dives beneath another, effectively recycling the planet's crust. This process pulls rock deep into the mantle, where intense heat melts it, eventually forming new crust at other locations.
