What can up and down faulting also be called?

Up and down faulting can also be called normal faulting or graben faulting, depending on the specific geological context. These terms refer to the movement of rock blocks along faults, where one block moves downward relative to the other.


What are the 3 different types of rock movement in earthquakes?

The three different types of rock movement in earthquakes are normal (extensional) faulting, reverse (compressional) faulting, and strike-slip (lateral) faulting. Normal faulting occurs when rocks are pulled apart, reverse faulting involves rocks being pushed together, and strike-slip faulting involves horizontal movement along a fault line.


What are the 2 types of faultung?

The two main types of faulting are normal faulting, where the hanging wall moves down relative to the footwall, and reverse faulting, where the hanging wall moves up relative to the footwall.


Describe the way a geologist can tell if a mountain chain was formed by the faulting of large blocks?

A geologist can tell if a mountain chain was formed by faulting of large blocks by looking for evidence of large-scale displacement along fault lines, such as offset layers of rock or distinctive patterns of tilting and deformation. Additionally, the presence of extensive fault networks and associated earthquakes supports the theory of block faulting as the mechanism of mountain chain formation. Topographic features, such as long, linear mountain ranges with distinct fault lines, are also indicative of block faulting.


What is contraction theory of diastrophism?

Contraction theory of diastrophism suggests that the Earth's crust undergoes compression, leading to the formation of mountain ranges and other structures due to the crust being forced to shorten and thicken. This theory explains the mechanisms behind the folding and faulting of rock layers, which are common features in regions with compressional tectonic forces.
