What physical process occurs during an airburst when a meteoroid enters the atmosphere at high speeds?
Answer
The object compresses the air in front of it, creating extreme heat and pressure that shatters the rock
When a meteoroid travels at tens of thousands of miles per hour, the atmosphere cannot move out of its path quickly enough. This results in the object rapidly compressing the air in front of it. This compression generates an immense shockwave and extreme localized heat and pressure. If the object is not structurally strong enough, these forces cause it to fracture and disintegrate mid-air. This process releases the object's kinetic energy as a shockwave, which can cause significant damage on the ground even if the physical pieces of the rock do not reach the surface.
