a normal fault
In a normal fault the hanging wall moves downward. With this type of fault, the hanging wall also shifts horizontally away from the fault line.
As the Earth's crust becomes denser, it typically moves downward into the mantle in a process known as subduction. This occurs at convergent plate boundaries, where an oceanic plate subducts beneath a continental plate or another oceanic plate. The denser oceanic crust sinks into the mantle, leading to geological phenomena such as earthquakes and volcanic activity.
The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
tectonic plates shifting. One moves under another and this causes the growth of new crust
Normal faults move because of tension, which causes the hanging wall to move downward relative to the footwall. This type of faulting occurs in areas where the Earth's crust is being pulled apart, and can create features such as rift valleys and horst-and-graben structures.

The esophagus moves food downward without performing any digestive functions.
In a normal fault, the crust moves along a downward sloping fault plane, with the hanging wall moving down relative to the footwall. This movement is caused by tensional stresses pulling the crust apart.
The earth's crust moves and the crust moves up When you have something like the rifting of a continent, the lithosphere heats up and causes it to rise. sinking of craton edges can be caused by things like tectonic loading.
Convection currents.
The earth crust consists of about 7 big plates, continents, and when they move towards each other 2 things can happen. 1. one plate moves under the other 2. the collide and both 'rise'. The plates constantly moves because of the different temperatures of the magma under the earth's crust.
Fault-block mountains are caused by normal faults, where blocks of the Earth's crust are tilted and uplifted along a fault line. As the hanging wall block moves downward relative to the footwall block, it creates a steep mountain range with a characteristic block-like appearance.
