Divergent boundaries:
Diverging boundaries is when the tectonic plates move away from each other, causing a gap in the surface which is then filled with magma that creates new crust along the boundary. These are called convection currents.
As a result of this, earthquakes occur along the faults and volcanoes form where the magma reaches the surface. Either new crust is created or plates pull away from each other.
When a divergent boundary crosses the land it causes rift valleys which are 30-50km wide. An example of this is the East Africa Rift in Kenya. When a divergent boundary crosses the ocean floor, the rift valley is narrower and is only a kilometre or less and it runs on top of a mid oceanic ridge. An example of this is the Mid-Atlantic Ridge.
