Divergent+Boundaries

=Title:= A divergent boundary occurs when 2 plate tectonics move away from each other. (separate)



=Locations:=

Continental<>Continental is located in the east Africa Rift Valley. It is still above sea level, and at an early stage of development. It is also occupied by lakes.

Oceanic<--->Oceanic is located in the Mid-Atlantic Ridge. There is a convection current below which causes magma to rise. The ridge is high compared to the surrounding sea floor.

=Associated Geologic Features:= Divergent boundaries form a **rift valley** ( linear shaped lowland between highlands and mountain ranges) and **volcanic islands** (they occur when plates move apart to create gaps which hot lava rises to fill). Most divergent boundaries that are between oceanic plates are called **mid- oceanic ridges**.
