An ocean trench is where old crustal material is pushed under another plate where it is melted and turned into magma.
The mid-ocean ridge is the world's longest continuous mountain range, stretching over 65,000 kilometers (40,000 miles) across the globe. Located primarily along divergent tectonic plate boundaries, these underwater ridges play a crucial role in shaping Earth's geological landscape through the process of seafloor spreading and volcanic activity.
