Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the associated phenomenon (nuclear)?Radioactive fallout, the descent of radioactive particles entrained in the cloud
2. How does a mushroom cloud form?The explosion creates superheated gas that is less dense than the air. The gas rises, pulls in air and debris, and when it reaches a height where its density matches the air, it spreads out to make the cap.
3. Why do mushroom clouds look like mushrooms?The rising hot gas makes a tall column (the stem) and when it spreads out at the top it forms a round, cap‑shaped part, just like a mushroom.

Rayleigh–Taylor Instability: A phenomenon occurring at the interface of two fluids of different densities when the lighter fluid is accelerated into the heavier fluid.
Entrainment: The process by which a moving fluid draws in and incorporates surrounding fluid or particles.
Stabilization Altitude: The atmospheric level at which the rising plume's density matches the ambient air, halting vertical ascent.
