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.
High concentrations are also in sub-tropical regions due to high rates of evaporation (clear skies, little rain, and prevailing winds) and in landlocked seas in arid regions. At high latitudes, salinity is low. This can be attributed to lower evaporation rates and the melting of ice that dilutes seawater.To sum up, salinity is low where precipitation is greater than evaporation, mainly in coastal or equatorial regions.hroughout Earth's history, certain processes have served to make the ocean salty. The weathering of rocks delivers minerals, including salt, into the ocean. Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean.
