An impact can be a collision or a crash.
From late Latin impactus , 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 home could not withstand the impact of the hail and ended up collapsing with its inhabitants inside,” “When both players "They jumped to head, there was a strong impact between their heads and they had to be hospitalized."
Impact is also the mark or sign left by the aforementioned crash: “The impact of the meteorite in the field can be clearly seen from the helicopter” , “The bullet impacts on the door of the business are a clear testimony of the violence of the robbery” , “The living room wall shows the impact of a ball, irrefutable proof that someone was playing soccer inside the house.”
A emotional blow
The emotional shock caused by surprising or disconcerting news and the effect produced by an event on public opinion are known as impact.
“When he found out about his son's death, the impact was enormous”, “Lara is still trying to get over the impact: it is clear that she needs more time” y “The president's resignation caused a great impact on society” son expresiones que muestran este uso.
An emotional blow is mentioned as an impact.
Environmental impact
The notion of environmental impact , on the other hand, refers to the effect that human activity generates on the environment .
It is common for the concept to be used to name the collateral effects that a certain economic exploitation has on the natural environment: “Mining is a very profitable activity for companies but with enormous environmental impact for the people.”
ancient kites
Studies carried out on a brooch belonging to Tutankhamun have revealed that one of its stones may belong to a comet that hit our atmosphere around 28 million years ago, according to what analysts announced through the scientific interest magazine « Earth and Planetary Science Letters . This is a discovery capable of clarifying many of the questions surrounding the origin of the Solar System.
Apparently, when said comet entered the earth's atmosphere, it exploded over Egypt and the heat it radiated brought the sand to a temperature of around 2,000 degrees Celsius. This impact left behind a considerable amount of silica glass that is generally known as Libyan desert glass and that has been of great interest to scholars in various areas for years.
Regarding the brooch of the ancient pharaoh, it presents the figure of a scarab polished in a crystal of this type, with its characteristic yellow color. Jan Kramer, one of the experts from the University of Johannesburg in charge of this research, assures that this is the first example of a comet nucleus that humans have ever known.
It is also believed that diamonds of microscopic dimensions emerged from the explosion. According to Kramer, carbon support material is needed for the production of diamonds, 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 .
It should be noted that the discovery of comet material 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 into space to collect tiny samples, which they study once they arrive on Earth.
