What types of fault is formed when plates diverge or pull apart?
Tension in Earth's crust pulls rock apart, causing hanging walls. In a normal fault, the fault is at an angle, so one block of rock lies above the fault while the other block lies below the fault. The block of rock that lies above is called the hanging wall. The rock that lies below is called the footwall.

The block of rock that lies above is called the hanging wall. The rock that lies below is called the footwall.
What do you call a block of rock that lies below the plane of the fault?
A block of rock that lies below the plane of a fault is called the "footwall." In contrast, the block of rock that lies above the fault plane is referred to as the "hanging wall." The terms are commonly used in geology to describe the relative positions of these blocks in relation to a fault.
What is a block of rock above a fault?
A block of rock above a fault is called the hanging wall. In a fault, the hanging wall is the block of rock that is positioned above the fault plane, while the block below the fault is called the footwall.
What is a block of rock that lies below the plane of a fault?
A block of rock below the plane of a fault is known as the hanging wall. It is the rock mass that is located above the fault plane and typically moves downward relative to the footwall during fault movement.
What is the foot wall and hanging wall?
In geology, the footwall is the block of rock that lies below a fault plane, while the hanging wall is the block of rock that lies above the fault plane. These terms are used to describe the relative positions of rocks on either side of a fault.
What is land mass called above a fault?
The land mass above a fault is typically referred to as the hanging wall. This is the block of rock that lies above the fault plane in a fault system. Opposite to the hanging wall is the footwall, which is located below the fault plane.
What is the area rock immediately above a fault surface?
The area of rock immediately above a fault surface is called the hanging wall. It is the block of rock that hangs or rests above the fault plane.
Difference between hanging wall and footwall?
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.The names come about from the mining industry because important ore minerals were commonly deposited along fault planes. In a mine along a fault, the miner would be standing on the block lower block and hanging his lantern from the upper block (hence, foot wall and hanging wall).In perfectly vertical faults, you cannot designate a footwall or a hanging wall.
What is another name of a normal fault?
In a normal fault, the fault is at an angle, so one block of rock lies above the fault while the other lies below it. The rock above it is the hanging wall and the rock below it is the footwall. In a normal fault, the hanging wall moves downwards relative to the footwall.
What is the definition of a hanging wall?
The hanging wall is the block of rock that lies above an inclined fault plane or dip in the Earth's crust. It moves down relative to the footwall during faulting or mining activities.
When a fault is not vertical a hanging wall and what are formed?
When a fault is not vertical, a hanging wall and footwall are formed. The hanging wall is the block of rock above the fault plane, while the footwall is the block of rock below the fault plane. These terms help geologists describe the displacement and movement along the fault.
