From late Latin impactus, he impact is the collision or collision of two objects or beings . For example: "The impact between the train and the bus left three people dead and dozens injured.", “The precarious housing did not support the impact of hail and ended up by collapse with its inhabitants inside ”, "When both players jumped to head, there was a strong impact between their heads and they had to be hospitalized".
Impact is also the paw print or signal that leaves the aforementioned shock: "The impact of the meteorite on the field can be clearly seen from the helicopter", "The bullet impacts at the door of the business are a clear testament to the violence of theft", "The wall of the room shows the impact of a ball, irrefutable proof that someone was playing football inside the house".
He mood hit caused by a News surprise or disconcerting and the effect produced by an event in public opinion they are known as impact: "When he learned of his son's death, the impact was enormous.", "Lara is still trying to overcome the impact: she obviously needs more time", "The resignation of the president caused a great impact on society".
The notion of environmental impact , on the other hand, refers to the effect that generates human activity on the environment . It is common for the concept to be used to name the collateral effects that a given economic exploitation has on the natural environment: “Mining is a very profitable activity for companies but of enormous environmental impact for the people”.
Studies on a brooch belonging to Tutankhamon have revealed that one of its stones may belong to a Kite which impacted our atmosphere about 28 million years ago, analysts said through the journal of scientific interest "Earth and Planetary Science Letters"It is a discovery capable of clarifying many of the questions that revolve around the origin of the Solar System.
Apparently, when said comet entered the earth's atmosphere, exploded over Egypt and the heat it radiated brought the sand to a temperature that was around 2,000 degrees Celsius. This impact left behind a considerable amount of silica glass that is generally known as desert glass of Libya and that years ago is of great interest for scholars of various areas.
With respect to the brooch of the old pharaoh, it presents the figure of a polished beetle on a glass of this class, with its characteristic yellow color. Jan Kramer, one of the experts from the University of Johannesburg in charge of this research, says that we are facing the first copy of the nucleus of a comet that the human being has known.
It is also believed that diamonds of microscopic dimensions emerged from the explosion. According to Kramer, carbon support material is needed for diamond production, which usually occurs in the depths of our planet, where the pressure level is very high; but in the same way it is possible that an impact of considerable magnitude generates the necessary pressure on the surface, precisely what happened when the comet collided with the Earth, and on this the scientist bases his theory.
Finally, the finding of material Comet on the Earth's surface can result in savings of several billion for NASA and ESA (its European version); Every year, these associations send expeditions to space to collect very small samples, which they study once they arrive on Earth.
