Name the correct order of rifting events.
balandron [24]

Rifting events:

• crustal up-warp,  

• rift valley (linear-shaped lowland between several mountains)

• linear sea,  

• ocean

Development of the rift starts when the upper part of the lithosphere starts to extend. Extension leads to the development of isolated basins. Major rifts occur along the central axis of most mid-ocean ridges, between two tectonic plates.
