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.
â¢ Lithification refers to the processes by which unconsolidated sediments are transformed into solid sedimentary rock. Most sedimentary rocks are lithified by means of compaction and/or cementation. Compaction occurs when the weight of overlying materials compresses the deeper sediments.
