Meteorite blast in Russia injures hundreds

When a meteorite enters the atmosphere at high speed, friction causes it to heat up and melt, forming a fireball that can reach 3,000 degrees Fahrenheit. This can lead to an explosion in the atmosphere, creating a shockwave. An example of this occurred over Eastern Russia, where a meteorite exploded at an altitude of 10 to 20 kilometers, resulting in a shockwave that injured hundreds of people.
