WebOne such tectonic process is known as “rifting,” where a tectonic plate gets extended and forms structures as in East Africa on Earth. These rift structures have been observed on Venus as well, but it is unclear how they formed under Venus' high surface temperature and pressure.

WebExplanation: The breakup of the continents that formed Pangea was caused by rifting, which is the process where the Earth's crust is pulled apart due to tectonic forces. This led to the formation of new ocean basins, such as the Atlantic Ocean, and the separation of the continents.

"WebTo study the rifting process and the formation of the axial deeps, we interpret three new reflection seismic profiles perpendicular to the rift axis. The eastern ends of the three profiles reach different axial zones of the Central Red Sea Rift ( Figure 1 b), providing a chance to reveal evolution from axial deeps to the inter-trough zones.

WebThe development of a rifting affecting the South Iberian Margin generated basins with alpine-like platforms (extended and wide, and structured in horsts and grabens), characterized by marine domains which are deeper from north to south, forming the Prebetic (to the north) and the Subbetic (to the south) of the EBZ [7,8,9]. WebSep 14, 2024 · Continental rifting is the process by which continental lithosphere undergoes horizontal extension, creating a rift zone (Burke & Dewey, 1973). During rifting, the lithosphere stretches roughly perpendicular to the trend of the rift. We distinguish between active and inactive rifts, based on the timing of extension.

WebMay 1, 2013 · A considerable controversy exists about the role of the mantle during rifting, the subsequent formation of oceanic crust, and the precise nature of volcanism in the rifting process. There are two end-member extremes of passive rifted margins: (1) volcanic rifted margins and (2) magma-poor rifted margins.
