Morphology

mushroom + cloud

The meaning is directly compositional: 'mushroom' describes a shape and 'cloud' is a visible mass in the sky, so a B1 learner who knows both words can infer a cloud shaped like a mushroom. The specialized association with explosions (especially nuclear) may require exposure, but the core visual/compositional meaning is transparent and follows a common cross-linguistic pattern.

Etymology

Mushroom cloud comes from the way smoke and hot air from a very large explosion rise, making a thin 'stem' and a wide top like a mushroom. That's why people call the tall cloud seen after a big explosion, often a 'nuclear' one.
