Which of the following landforms is not produced by faulting?

The landform that is not produced by faulting is a sill. Sills are horizontal intrusions of magma that solidify between layers of sedimentary or volcanic rock. They are not formed by faulting, which occurs when rocks along a fault line move relative to one another due to tectonic forces. On the other hand, a fault scarp is a cliff or steep slope that is created by the displacement of rock along a fault line. A rift valley is a lowland region that forms between two diverging tectonic plates. A horst is a raised block of land that is bounded by normal faults. Therefore, the correct answer is sill.
