WebChapter 2 Plate Tectonics Assignment My answers are highlighted like this. 1. Explain why the discovery of the fossil remains of Mesosaurus in both South America and Africa, but nowhere else, supports the continental drift hypothesis. If Mesasaurus were able to travel such distances we would have found their fossils in more places as well. WebA rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional …

WebThe concept of rift–raft tectonics was developed by Penge et al (1993) to describe structures formed above a salt substrate along the shallow margins of the East Central Graben. These structures were formed initially during the late Triassic–early Jurassic basement extension and modified by later Jurassic and Cretaceous phases.

In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where … See more Most rifts consist of a series of separate segments that together form the linear zone characteristic of rifts. The individual rift segments have a dominantly half-graben geometry, controlled by a single basin-bounding … See more Many rifts are the sites of at least minor magmatic activity, particularly in the early stages of rifting.
