In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides , with the brightest air bursts known as superbolides .
The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere since the 1908 Tunguska event, [23] [24] [25] and the only one confirmed to have resulted in many injuries, [26] [Note 1] although a small number of panic-related injuries occurred during the Great Madrid Meteor Event of 10 February 1896.
Desert glass – natural glass found in deserts formed from the silica in sand as a result of lightning strikes or meteor impacts. Differentiated – a meteorite that has undergone igneous differentiation. (See: achondrite) Differentiation – usually the process of a planetesimal forming an iron core and silicate mantle.
Scientists believe they can find a meteor blast in Earth’s history strong enough to change the climate and, as a result, the animals that lived on Earth. Evidence may exist for a comet shockwave ...
[100] [101] The Chelyabinsk meteor was estimated to have caused over $30 million in damage. [102] [103] It is the largest recorded object to have encountered the Earth since the 1908 Tunguska event. [104] [105] The meteor is estimated to have an initial diameter of 17–20 metres and a mass of roughly 10,000 tonnes. On 16 October 2013, a team ...

Conical shockwave with its hyperbola-shaped ground contact zone in yellow. A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.
