Puberty, Teenagers. Adolescence typically describes the years between ages 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or tween years (ages 9 through 12).
Puberty occurs during adolescence, which begins as early as age 10 and is usually completed by age 17. For girls, a rising level of oestrogen (female hormone) sets the process in motion. Pelvis and breast development are followed by a spurt in height and then the growth of underarm and pubic hair.
