The day of the first atomic bomb explosion – level 1


On July 16, 1945, the United States does the first successful test of an atomic bomb. It happens in New Mexico.

The atomic bomb is a top-secret project. The United States wants to be the first country which makes an atomic bomb.

The explosion of the bomb makes a big cloud. The cloud looks like a mushroom. The cloud is 12 km high. People can feel the power of the explosion 160 km away.

Three weeks after the successful test, the United States uses an atomic bomb against Japan.

Difficult words: top-secret (extremely secret), explosion (a moment when an object quickly changes into many small pieces).

What would be the long-term effect of the atomic bomb on the US-Japan relationship?
