which statement explains one reason why unconformities occur? rocks along a fault break and move. igneous rock forms at earth’s surface. no sediment is deposited over a long time. igneous rock forms between sedimentary layers.

which statement explains one reason why unconformities occur? rocks along a fault break and move. igneous rock forms at earth’s surface. no sediment is deposited over a long time. igneous rock forms between sedimentary layers.

Answer

Brief Explanations:

Unconformities are gaps in the geologic record. When no sediment is deposited over a long - time, a gap forms in the rock layers, leading to an unconformity. Faulting (rocks along a fault break and move) is related to structural deformation, not directly to unconformities. Igneous rock forming at Earth's surface or between sedimentary layers doesn't directly explain the formation of unconformities.

Answer:

No sediment is deposited over a long time.
