Answer:
Puberty is the process of physical changes through which a child's body matures into an adult body capable of reproduction. It is initiated by hormonal signals surging through the body.
It's not just physical.
During puberty, a child's emotions may become stronger and more intense. Their mood might change more frequently, quickly, and randomly. The child may have strong emotions that they've never experienced before. It's common for them to feel confused, scared, or angry and not know why.
It also affects the brain. Research shows changes in hormones also attach to your brain cells and change how the brain learns and grows. These changes are useful because they help shape the brain for new forms of learning.
