Morphology
The compound 'rocket propulsion' is directly built from 'rocket' (a rocket vehicle) and 'propulsion' (the force that drives something forward), so a learner who knows both words can infer it refers to the means or force that propels rockets. While some technical details (e.g. stored oxygen, combustion) are specialized, the core idea is compositional and follows common noun+noun naming patterns, making it accessible to B1 learners.
Etymology
Rocket propulsion is easy to remember with a balloon: when you let a filled balloon go, the air rushes out the back and the balloon flies forward. A rocket does the same but carries its own 'air' to burn, so propulsion means this push from fast gases that moves a craft even in empty space.
