During adolescence, several physical, emotional, and social changes take place as individuals transition from childhood to adulthood. Here are some typical examples of changes that occur:

1. Physical Changes:
   • Puberty: Adolescents experience growth spurts, and their bodies undergo hormonal changes. For girls, this includes breast development, menstruation, and widening of hips. For boys, changes include the growth of facial hair, deeper voice, and increased muscle mass.
   • Sexual Maturity: Both boys and girls develop secondary sexual characteristics, such as the growth of pubic hair and changes in reproductive organs.
2. Emotional Changes:
   • Mood Swings: Hormonal changes can cause fluctuations in mood, leading to feelings of sadness, anger, or happiness within short periods. Adolescents may also experience heightened emotions as they deal with new challenges.
   • Increased Sensitivity: Teenagers often become more sensitive to criticism and may experience anxiety or stress about how they are perceived by others.
3. Social Changes:
   • Peer Influence: Adolescents tend to place more importance on their relationships with friends and may be influenced by peer pressure. Friendships become more central to their lives, and fitting in socially is often a major concern.
   • Seeking Independence: Teenagers typically seek more autonomy from parents or guardians. They start making more decisions for themselves and may test boundaries as they develop a sense of identity and independence.

These changes are normal and part of the process of growing into adulthood, though they can sometimes lead to challenges for both adolescents and those around them.
