Final answer:
Social solidarity is the dimension of cohesion known as peer bonding, which becomes highly significant in adolescence as peers become a primary agent of socialization.
Step-by-step explanation:
The dimension of cohesion also known as peer bonding is referred to as social solidarity. This concept relates to the social ties that bind a group of people together through aspects such as kinship, shared location, and common interests. In adolescence, peer bonding becomes particularly significant as individuals begin to form their own identities, pulling away from parental influences and relying more on their peer groups. The peer group is a critical agent of socialization, teaching social norms and influencing behaviors and attitudes during the formative years. High-quality relationships within peer groups can contribute to positive outcomes, such as better grades and fewer behavioral problems in school.
