The dip of the inclined layers are shown using strike-and-dip symbols. If the layers are horizontal, they are depicted with a symbol that is a circle with a cross inside. On the geologic map, the faults are shown as heavy black lines with an arrow indicating the direction and amount in which the fault dips.

Based along line A-A', why is the outcrop width of the Kincaid Limestone (Mkc) greater on the eastern side of the syncline than on the western side?

The unit is faulted and dips more steeply on the western side than it does on the eastern side.

It is eroded along an unconformity below the Rosiclare Sandstone.

It is eroded along an unconformity below the Tar Spring Sandstone.

The unit dips ore steeply on the eastern side than it does on the western side.

2. The arrows on the faults indicate which way the fault dips. What type of fault is most common in the area along A-A'?

Thrust faults

Reverse faults

Normal faults
