The type of rock layers found on one side of the fault will either be repeated higher or lower on the other side of the fault. This proves that one side of a fault has moved (slipped).
Fault
Along a fault, rock layers can become displaced, offset, or tilted. This is due to the movement of the Earth's crust along the fault line, resulting in different rock layers being shifted relative to each other.
A fault that occurs on folded rock layers is likely to be a thrust fault, where one block of rock is pushed up and over the other. This type of fault is common in areas where horizontal compression forces have folded the rock layers.
Not necessarily. Rock layers along a strike-slip fault may be offset if they are dipping.
A Fault
The relative age of the fault is younger than the sedimentary rock layers it cuts across. The fault must have formed after the deposition of the sedimentary rock layers, as it disrupts them.
Faulting is caused by stress in the rock layers, the stress can break and crack the rock causing a fault. There are two types of faults a normal fault and a reverse fault.
A Fold (anticline or syncline) - but it is not a fault. A geological Fault is a break in the rock, with the rock on one side moved relative to that on the other..
The rock layers that a fault passes through had to have already existed for them to break and create a fault. This is analogous to the door panel of your car had to have already existed for it to bend and create a dent.
If a fault occurs in an area where rock layers have been folded, the type of fault it is likely to be is thrust faulting. This type of fault will have the ground on one side of the fault, move up and over adjacent ground.
FAULT
What is the relative age of a fault that cuts across three horizontal sedimentary rock layers?A. The fault is older than the middle layer. B.The fault is younger than all the layers it cuts across.C. The fault is the same age as the top layer. D. The fault is older than all the layers it cuts across == ==
