... A nappe is a large sheetlike body of rock that has been moved more than 2 km (1.2 miles) from its original position. Nappes form during continental plate collisions, when folds are sheared so much that they fold back over on themselves and break apart. The resulting structure is a large-scale recumb ...

The Ridge push model suggests that the driving force of plate tectonics are divergent boundaries Suggests that as divergent boundaries are elevated above the rest of the ocean floor they push the lithospheric plates as they diverge It is likely that all these forces are contributing to tectonic move ...

Basalt
Basalt (pronounced /bəˈsɔːlt/, /ˈbæsɒlt/, /ˈbæsɔːlt/, or /ˈbeɪsɔːlt/)is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
