What is fault describe the different types of fault with neat sketches?

Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.

What are the different types of fault?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.

What are the types of fault and explain each?

Normal faults form when the hanging wall drops down. Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together. Transcurrent or Strike-slip faults have walls that move sideways, not up or down.

What are the 3 major types of faults?

There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip. Figure 1 shows the types of faults that can cause earthquakes. Figures 2 and 3 show the location of large earthquakes over the past few decades.

How are the different types of faults different?

Different types of Faults 1 Where the crust is being pulled apart, normal faulting occurs, in which the overlying (hanging-wall) block moves down… 2 Where the crust is being compressed, reverse faulting occurs, in which the hanging-wall block moves up and over the… More

How to explain different types of keys with neat sketches?

Explain different type of keys with neat sketches. Explain different type of keys with neat sketches. Splines. A sunk key is a key in which half the thickness of the key fits into the keyway on the shaft and the remaining half in the keyway on the hub.

What kind of fault occurs on a gently inclined plane?

Where the crust is being compressed, reverse faulting occurs, in which the hanging-wall block moves up and over the footwall block – reverse slip on a gently inclined plane is referred to as thrust faulting.

What kind of faults move sideways past each other?

3. Crustal blocks may also move sideways past each other, usually along nearly-vertical faults. This ‘strike-slip’ movement is described as sinistral when the far side moves to the left, and dextral, when the far side moves to the right.
