Final answer:
Adolescence involves teenagers developing their system of moral and ethical values, experiencing psychosocial changes, and tackling the challenge of identity versus role confusion.
Step-by-step explanation:
Adolescence is the time when teenagers will compare themselves to each other as they develop their system of moral and ethical values. During this crucial developmental stage, which spans roughly from ages 12 to 18, teens work through the task of identity versus role confusion, facing questions like "Who am I?" and "What do I want to do with my life?". As they explore various roles and beliefs, this period is characterized by several psychosocial changes, such as an increasing need for peer acceptance, heightened self-awareness, and a shift toward greater emotional independence from parents. Additionally, teens may engage in romantic relationships for the first time and grapple with the physical developments of puberty, which can influence their self-esteem and body image.
