The A Passive Margin is the area between two continents that is separated by an ocean. Passive margins consist of the sloping or tapering wedge from the continental surface or crust toward the ocean bed. They are found at ocean and continent boundaries. Oil and gas reservoirs are found in the passive margins and oil and gas exploration is carried out in these regions. Passive margins have been the reliable, accessible mainstay of exploration success worldwide for the last 25 years, and have hosted the spectacularly fast exploitation of deepwater resources (Angola, Nigeria, Brazil, Trinidad, USA Gulf of Mexico, Egypt, Australia and India).

These are a lot less steep continental slopes and larger continental shelves.

Geometry of passive margins. Rifted margin The variation in focal mechanisms across the margin suggests a spatially varying stress field. Although the later feature may not be a general characteristic, the empiricism that passive margin seismicity seems most evident on recently deglaciated margins suggests that deglaciation is at least partially responsible for the earthquakes. Passive margin: North Carolina's Outer Banks region showing coastal plain, rivers, tidal estuaries, lagoon, barrier islands, and shallow Atlantic continental shelf Emergent and Submergent Coasts In some regions around the world, tectonic forces are pushing rocks up along coastal regions, mostly in regions associated with active continental margins.

Because there is no collision or subduction taking place, tectonic activity is minimal and the earth's weathering and erosional processes are winning. This leads to lots of low-relief (flat) Passive margins consist of the sloping or tapering wedge from the continental surface or crust toward the ocean bed.

Passive continental margins are continental margins that are not tectonically active. These areas have flat lands and have a wide continental shelf , which is the submerged border of the continent.

Passive continental margins develop along coastlines that are not tectonically active, including much of the Atlantic Ocean coastline. Many passive continental margins have a continental rise, a very low‐angle ridge of sediment that forms between the continental slope and the abyssal plain (Figure ). The sediments that form the continental rise are Progression of continental rifting to sea floor spreading creates paired (conjugate) passive margins over which post-rift successions accumulate across crust transitional between fully continental and fully oceanic. Passive continental margins are continental margins that are not tectonically active.
