Final answer:
The stage of physical development during adolescence is called puberty. It involves the maturation of sexual and physical characteristics, growth spurts, and hormonal changes. These changes have an impact on emotional and mental development as well.
Step-by-step explanation:
The stage of physical development during adolescence is called puberty. Puberty is the time when sexual and physical maturation occurs, leading to significant changes in the body. These changes include the development of secondary sexual characteristics, such as breast growth in girls and the deepening of the voice in boys. Puberty also involves growth spurts, increased sweat production, and the onset of menstruation in girls. These physical changes are accompanied by hormonal changes that have an impact on emotional and mental development as well.
The pre-adolescence stage typically covers ages 11 to 12 years and is often characterized by the onset of puberty. While it is considered a unique stage, few of the more obvious physical changes, such as sexual maturation, are present. There is, however, significant cognitive and psychosocial development, introducing abstract thought and greater understanding of cause and effect.
As adolescents transition to adulthood, they go through early, middle, and late stages. By early adulthood, physical maturation is complete, and individuals are at the peak of their physical abilities. Each stage of adulthood brings its own physical, cognitive, and social changes.
