Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock.
Reverse fault hanging wall and footwall.
If we hold the foot wall stationary where would the hanging wall go if we reversed gravity.
The hanging wall will slide upwards right.
In a non vertical fault where the fault plane dips the footwall is the section of the fault that lies under the fault while the hanging wall lies over the fault.
When movement along a fault is the reverse of what you would expect with normal gravity we call them reverse faults.
Where the fault plane is sloping as with normal and reverse faults the upper side is the hanging wall and the lower side is the footwall.
The movement along the thrust fault is the foot wall goes down and the hanging wall goes up.
This is a landform made from volcanism.
The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults.
Strike slip faults have a different type of movement than normal and reverse faults.
Its also called a reverse fault because a normal fault has the foot wall going up and the hanging wall.
The names come about from the.
The reverse faults occur when the hanging wall works its way up the footwall.
This is the result of tension built up.
2 1 volcanism is the process by which molten rock reaches the earth s surface in order to make new landforms.
These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing.
The line it makes on the earth s surface is the fault trace.
It is a flat surface that may be vertical or sloping.
The fault plane is where the action is.
When the fault plane is vertical there is no hanging wall or footwall.
