Web(ii) Block mountains may be formed when the side blocks of two faults move downward whereas the middle block remains stable at its place (fig. 11.1 B). It is apparent that the middle block projects above the surrounding surface because of downward movement of side blocks. Such block mountains are generally formed in high plateaux or broad … Web11 feb. 2024 · The basin and range topography develops over a few million years as fault lines move gradually, or more abruptly during tens of thousands of earthquakes. The colder upper crust cracks and breaks along faults (like peanut brittle), causing earthquakes and forming long mountains (ranges) separated by valleys (basins). how to round numbers in alteryx

Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust. Large areas of bedrock are broken up into blocks by faults. Blocks are characterized by relatively uniform lithology. The largest of these fault blocks are called crustal … Meer weergeven Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone.

Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
