Why do rockets break up?

Rockets can break up due to various factors, including structural failure from excessive aerodynamic forces, engine malfunctions, or issues related to fuel and propulsion. For instance, if a rocket experiences unanticipated stresses during ascent, it may exceed its structural limits. Additionally, failures in guidance systems can lead to loss of control, causing disintegration. Environmental factors, such as extreme temperatures and pressures, can also contribute to a rocket's breakup.
