One caveat: If your toddler is overweight, at risk for becoming overweight, if you have a family history of obesity, high blood pressure or heart disease, your pediatrician may recommend that your toddler drink 2% milk from age 1 to 2 instead of whole milk. But don't give her 1% or skim milk before age 2.
The final sediment thus reflects the energy of the transporting medium. Lithification (Diagenesis) - Lithification is the process that turns sediment into rock. The first stage of the process is compaction. Compaction occurs as the weight of the overlying material increases. Compaction forces the grains closer together, reducing pore space and eliminating some of the contained water. Some of this water may carry mineral components in solution, and these constituents may later precipitate as new minerals in the pore spaces.
It is to be noted that the variations in salinity are the result of certain physical processes like evaporation, precipitation and freezing. Salinity decreases in case fresh water is added to the ocean water. It may be through any of the processes such as precipitation, influx of fresh water by rivers, surface runoff or the melting of snow and ice etc.
