What is mushroom cloud?

Question

Atom bomb explosion.

Answer 1

A mushroom cloud is a distinctive mushroom-shaped cloud of smoke, flame, or debris resulting from a very large explosion. They are most commonly associated with nuclear explosions, but any sufficiently large blast will produce the same sort of effect. Volcano eruptions and impact events can produce natural mushroom clouds.

Mushroom clouds form as a result of the sudden formation of a large mass of hot low-density gases near the ground creating a Rayleigh-Taylor instability. The mass of gas rises rapidly, resulting in turbulent vortices curling downward around its edges and drawing up a column of additional smoke and debris in the center to form its "stem". The mass of gas eventually reaches an altitude where it is no longer less dense than the surrounding air and disperses, the debris drawn upward from the ground scattering and drifting back down (see fallout).

The largest mushroom clouds to be photographed resulted from the impact of fragments of Comet Shoemaker-Levy 9 on the planet Jupiter, some of which rose hundreds of kilometers above the cloud layers.
Mushroom clouds are formed by many sorts of large explosions, though they are best known for their appearance after nuclear detonations. Nuclear weapons are usually detonated above the ground (not upon impact,or else they would dig a big hole in the ground) in order to maximize the effect of their spherical expanding fireball. After immediate detonation, the fireball itself begins to rise into the air, acting on the same principle as a hot-air balloon.

Answer 2

A Mushroom cloud is the visual aftereffect of a Hydrogen Bomb Explosion

Answer 3

When an atomic bomb explodes, a fireball creates shock and heat waves that destroy structures in the immediate vicinity of the blast. The rising fireball sucks up debris to form a mushroom cloud. Damage can occur over large distances. For example, the radius for severe damage could be approximately 18 km (11 mi) for a 10-megaton blast. Radioactive fallout may be dispersed worldwide through global atmospheric processes.

Answer 4

Exactly. Mushroom cloud is a descriptive name for the distinctive cloud that accompanies very large explosions, especially atomic blasts. The cloud rises so high that it reaches a thinner part of the atmosphere, where it widens sharply. Mushroom clouds are well known as a sign of the explosion of a nuclear bomb, but they can also be a part of volanic or impact events.

Answer 5

It always shows up after an atomic explosion or H-bomb.

Answer 6

i think a mushroom cloud is radioactive debris produced by a nuclear explosion or radioactive gas.

Answer 8

mix bleach and ammonia together in your toilet, then jump back and watch the seat blow off. lol. j/k kiddies, do not ever mix bleach and ammonia together. slaps self on the hand...bad pirate girl. off to the crow's nest with you for a time-out...again.
