rift
The landform feature that generally marks a divergent plate boundary is the plate tectonic. This is mainly responsible for the changes on the surface of the earth.Ê
The feature that marks the location where one tectonic plate is pushed underneath another plate is called a subduction zone. In these zones, the denser oceanic plate is typically forced down into the mantle beneath a lighter continental plate or another oceanic plate. This process can lead to the formation of deep ocean trenches and is often associated with volcanic activity and earthquakes.
The rift valley along a mid-ocean ridge marks where tectonic plates are moving apart. As the plates separate, magma rises to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
New oceanic crust is created at the mid-ocean ridges where rift volcanoes feed solidifying magma from the asthenosphere to both sides of the divergent plate boundaries. The mid-ocean ridge marks the line where heat from the Earth's interior is being carried to the surface by convection currents in the mantle. At the opposite end of the convection currents, colder, denser, and older oceanic crust is being drawn down into the asthenosphere, the birth to death of oceanic crust occurring in roughly 150 million year cycles.
The land feature that marks the division between Africa and Asia is the isthmus of Suez. Its found in Egypt and is about 125 kilometers wide.
ripple marks

Ripple marks are a feature of mountains that are not a direct result of mountain building.
The Mid-Atlantic Ridge is not actually a tectonic plate, but a divergent boundary between plates where new oceanic crust is being created on the floor of the Atlantic Ocean. To the north, it marks the boundary between the Eurasian Plate and the North American Plate. To the south, it separates the African Plate from the South American Plate.

The Mid-Atlantic Ridge separates the North American plate from the African plate. This ridge runs through the Atlantic Ocean and marks the boundary where the two plates are moving apart.
