Final answer:
True, Girls typically begin puberty earlier than boys, starting around age 10, with changes including breast development and menarche, while boys usually start around age 11 to 12.
Step-by-step explanation:
Puberty, the period of sexual maturation, follows a generally predictable timeline but can vary among individuals. On average, girls initiate puberty around the age of 10, a year or so earlier than boys who typically commence puberty between 11 to 12 years. The progression through puberty is swifter for girls, typically taking around 4 years, while boys undergo a more extended process lasting about 6 years. For girls, the initial signs include the development of breasts and pubic hair, marking the onset of physical changes. This is succeeded by a growth spurt, often occurring around mid-puberty, and culminates in menarche, the first menstrual period, signifying the completion of the puberty process. While the timeline provides a general framework, individual variations are common, emphasizing the dynamic and multifaceted nature of the pubertal journey.
