Don’t put a random answer istg- chile anywayss 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.

first let's look at what "unconformity" means "An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous." -google.

So that would make the answer D, "Igneous rock forms between sedimentary layers."

(also, the fact you said "chile" compelled me to look it up and help you're hilarious)

the indians would be mad that they would have to move since it caused many deaths known as the trail of tears they would of taken it to the supreme court but discrimination would have mad them lose
