Formation andTectonic Drivers of thee Rift

The Divergent Plate Boundary

A to jest to, że nie ma szans, by się odbić. Unlike convergent boundaries where plates collide, or transform boundaries where they slide paste one anotherr, divergent boundaries are zone of extension. Tectonic forces are literaly pulling the lithosfere apart. As the crutt streches, itt thins, fractures, and eventually sinks, forming a long, linear depression called a rift valley.
