What is the difference between a foot-wall fault and the hanging wall fault?
Take the fault as an inclined plane with the earths surface as the horizontal plane.The foot wall side of the fault is always located to the side where the plane of the fault and the horizontal forms an acute angle.The hanging wall side of the fault is always located to the side of the fault where the plane of the fault and the horizontal makes an obtuse angle.The terminology takes no regard to the direction of motion of the blocks either side of the fault. Thus for a dipping fault, the Hanging Wall is the block positioned over the fault and the Foot Wall is the block positioned under it.
Explain why there is a difference in the surface topography on either side of the fault line?
i dont even know and earth science is stupid.
What is meant by the word fault in terms of an earthquake?
A fault scarp is a vertical relocation of the ground along either side of a fault, usually after an earthquake, one side being higher than the other. It often marks the surface extension of a fault below. Scarps can be small or large, in some cases creating steep cliffs. An earthquake is caused when the rocks in the earth are distorted (by the slow moment of the tectonic plates that form the continents) to the point where they break and move past one another along a crack called a fault plane. If this fault plane comes to the surface of the earth then after the earthquake, the rocks on one side may have been moved so that they are now higher than the rocks on the other side. This means that a cliff has appeared along the fault and this cliff is called a fault scarp.
What can happen at a fault zone?
In geology, a fault or fault line is a planar fracture in rock in which the rock on one side of the fracture has moved with respect to the rock on the other side. Large faults within the Earth's crust are the result of differential or shear motion and active fault zones are the causal locations of most earthquakes. Earthquakes are caused by energy release during rapid slippage along a fault. A fault that runs along the boundary between two tectonic plates is called a transform fault.Since faults do not usually consist of a single, clean fracture, the term fault zone is used when referring to the zone of complex deformation that is associated with the fault plane. The two sides of a non-vertical fault are called the hanging wall and footwall. By definition, the hanging wall occurs above the fault and the footwall occurs below the fault. This terminology comes from mining. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall hanging above him.
Fault-block mountains are formed when a shift takes place along a fault line and?
When one side of the fault rises or drops

What fault has the hanging wall moving up to the foot wall?
Answer : Normal Fault Explanation : Normal fault is the cliche kinds of fault.It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture.
What makes a fault different from other kinds of fractures in rocks?
Rocks on either side of a fault move along the surface of the fault.
What type of fault rocks on either side of the fault surface moves past each other?
strike-slip
How are fault lines important to fault block mountains?
Fault-block mountains form because of fault-lines. One side of a fault pushes over the other, causing blocks of rock to rise from the surface.
What is a thrust fault is a?
A blind thrust fault is a geological term for a type of thrust fault which does not appear on the surface - where a hanging wall makes an angle with the horizontal of less than 45 degrees, but is hidden from view.
Is there a need to inclined a little bit the side of the pattern why?
yes to known the inclined plane and understand the need to be inclined

Rocks on either side of this move past each other without much upward or downward movement?
The "plates" shift. They move up and down, side to side, and forced against each other, one side may shift above the other
What is the inclined plane on a screw?
The ridges around the side
How are scarps formed?
Scarps are vertical displacements of the ground surface along a fault, which may be represented by small rises or by steep cliffs. A fault scarp with relatively level land on each side is also called an escarpment.
What is a fault scarp?
A geological landform, a scarp is a vertical relocation of the ground along either side of a fault, usually after an earthquake, one side being left higher than the other. It often marks the surface extension of an existing fault below. Scarps can be small or large, in some cases creating steep cliffs which may later erode.
