Origins and physical features

The Jordan Rift Valley was formed many millions of years ago in the Miocene

 moved northward and then eastward away from Africa. One million years later, the land between the Mediterranean and the Jordan Rift Valley rose so that the sea water stopped flooding the area.

The lowest point in the Jordan Rift Valley is at the shores of the Dead Sea, which is also the lowest point (on land) on the surface of the earth at 400 meters below sea level. Rising sharply to almost 1,000 meters in the west, and similarly in the east, the rift is a significant topographic feature over which few narrow paved roads and difficult mountain tracks lead. The valley north of the Dead Sea has long been a site of agriculture because of water available from the Jordan River and numerous springs located on the valley's flanks.

The Dead Sea Transform

, and the displacement along it is oblique, with approximately 10–15 km of extension in addition to the more substantial left lateral (sinistral) strike-slip. The evolution of the rift, according to this latter model, started in the late Miocene with the linear series of basins that propagated gradually along their axes to form the present rift valley. The elucidation of the nature of the Dead Sea Transform/Rift is a matter of ongoing study and discussion.

The Jordan Valley is several degrees warmer than adjacent areas, and its year-round agricultural climate, fertile soils and water supply made it a site for agriculture dating to about 10,000 years ago. By about 3000 BCE, produce from the valley was being exported to neighboring regions. The area's fertile lands were chronicled in the Hebrew Bible
