What is the behavior of soil properties with depth according to the given study?

The weight per unit volume decreases with depth due to the moisture content of the sample.
The shear wave velocity generally increases with depth.
The number of cycles is inversely proportional to the maximum shear stress and the shear modulus.
The damping of the soil decreases with depth and is higher in saturated conditions.
The elastic modulus and shear modulus decrease with depth and are directly proportional to each other.
