Detailed explanation-1: -If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
Detailed explanation-2: -They are comprised of small pieces of debris, typically no larger than a grain of dust or sand, which continually crash into the Earth’s atmosphere. As that debris plunges deeper and deeper, friction with the atmosphere causes it to ablate – burning up from the outside in.
Detailed explanation-3: -The collision may have caused much more dust than usual to enter Earth’s atmosphere. The influx of dust may have caused a global cooling that turned Earth into a colder, icier world. These peer-reviewed results were published on September 18 in the journal ScienceAdvances.
Detailed explanation-4: -Paul explains, ‘The asteroid hit at high velocity and effectively vaporised. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere. ‘It sent soot travelling all around the world.
Detailed explanation-5: -Asteroids, some of them quite large, fall into the Sun all the time. Absolutely nothing happens. In fact, if the entire Earth hit the Sun, nothing would happen to the Sun. Even if all of the planets in the solar system fell into the sun they’d all vaporize in an instant.
