When liquids are subjected to lower temperatures, the kinetic energy of the molecules would decrease accordingly making them closer to each other and leading to a decrease in volume until the substance is solidified. Hope this answers the question.
Are you speaking of a density gradient, in which a more concentrated solution moves below a less concentrated solution?
In that case, the more concentrated solution has the greater density, and it will gradually sink below the less concentrated solution.
In the same way, a stone will sink in water, which is less dense than the stone.
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.Earthquake shaking and other factors can also induce landslides underwater.
