Why are nuclear bombs detonated above ground?

Nuclear weapons For the Hiroshima bomb, an air burst 550 to 610 m (1,800 to 2,000 ft) above the ground was chosen “to achieve maximum blast effects, and to minimize residual radiation on the ground as it was hoped U.S. troops would soon occupy the city”.

What happens if nuclear bomb explodes in Ocean?

At the maximum diameter of the first oscillation, a very large nuclear bomb exploded in very deep water creates a bubble about a half-mile (800 m) wide in about one second and then contracts, which also takes about a second. Blast bubbles from deep nuclear explosions have slightly longer oscillations than shallow ones.

Does a nuclear bomb hit the ground?

When a nuclear weapon is detonated on or near Earth’s surface, the blast digs out a large crater. Some of the material that used in be in the crater is deposited on the rim of the crater; the rest is carried up into the air and returns to Earth as radioactive fallout.

Did the atomic bomb explode before it hit the ground?

The bomb never hit the ground, but exploded about 2,000 feet above the city – a height intended to cause maximum damage.

What is the biggest difference between a conventional bomb and atomic bomb?

How does a Nuclear Bomb differ from a Conventional Bomb? A conventional bomb releases most of its energy in the form of blast. Atomic bombs on the other hand, release 50 per cent energy as blast, 35 per cent as heat and 15 per cent as nuclear radiation.

What if we nuke the North Pole?

A single nuke would change a bit of ice and snow to water vapor which would promptly re-freeze. There would be a crater which would probably not be visible in a season or two.

How did little boy explode?

Little Boy triggered a nuclear explosion, rather than implosion, by firing one piece of uranium 235 into another. When enough U235 is brought together, the resulting fission chain reaction can produce a nuclear explosion. The plug was propelled down the cannon barrel by several thousand pounds of high explosive.
