Thats the only thing I can think of if you have options I could answer better.
The answer to this question is the second item in the choices which is "where older buildings were built on a thick layer of sediment". We know that seismic vibration is the sound or movement generated from the ground. This happening is unwanted and cannot be controlled. Once this occurs in higher magnitude it would cause great damage to our structure were buildings made of rock collapse.
Organisms that are buried in sediment may decay or dissolve away leaving a mold<span>. If the space is subsequently filled with sediment, an external </span>cast<span> can be made. </span>Molds<span> and </span>casts <span>are three dimensional and preserve the surface contours of the organism.</span>
