All rocks, once exposed on the surface of the Earth are subjected to processes of erosion, transportation and ultimately deposition. These topics are covered in detail in Geol. 201. For our current purposes, it is sufficient to state that such processes produce sediment which may ultimately be transformed into sedimentary rock. Sediment can be defined as any material that settles to the bottom of a fluid. Sedimentary rocks are classified in to three major categories based on the nature of the sediment. I. Detrital or Clastic Sediments These rocks are composed of fragments of pre-existing rock that have been eroded, transported and deposited in an accumulation that has subsequently been converted into a hard coherent sedimentary rock.
What is the age difference between a child an infant and a baby? infant 0 - 3 months baby 3 - 12 months toddler 1 - 3 years child 3 - 11 years in my opinion...
Infants between the age of 8-12 months are at particular risk, as the death of a parent during this period coincides with attachment and separation. As the age group moves up, children may act out in ways by retrograding to infant behavior. Adolescents may react by delinquency, or its opposite, overachieving. Early exposure to mortality also renders teens susceptible to suicide ideation. To note, the death of a parent often means the loss of family and social structure, hence often oldest child of many may assume the role of a parentified child.
