Seafloor Spreading: Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges as tectonic plates move apart.
Tectonic Plates:Tectonic plates are large pieces of Earth's lithosphere that fit together like a jigsaw puzzle and move due to convection currents in the underlying asthenosphere.
Convergent Boundary:A convergent boundary is a type of plate boundary where two tectonic plates collide or come together. This can result in the formation of mountains or subduction zones.
