7 ways asteroids destroy life on Earth

Strong winds, high pressure, heat radiation are three of the asteroid's effects when colliding with the Earth are capable of killing humans and many other organisms.

Scientists at the University of Southampton, UK, point out 7 different risks when the Earth collides with an asteroid, according to News.com.au. They published their findings in an article entitled " Asteroid Impact and Direct Risks to People ", published in AGU April 19.

The team used computer simulations to assess the risk posed by 50,000 different asteroids. The results show that asteroids that collide directly with land or explode in the sky cause more destruction and death than when they plunge into the sea and create a tsunami.

Gust

The wind formed when asteroids collided with the Earth causing the most serious effects. They can blow people and objects around, destroy houses. Researchers believe that just one asteroid measuring 18 meters wide is enough to cause many deaths and injuries.

The pressure is too high

Shock waves are created when asteroids explode in the air, or fall to land and sea. It causes a lot of damage and injuries to people, such as breaking the internal organs. Even if the asteroid is large enough, shock waves can crush the victim's body.

Shock waves also destroyed buildings, causing windows to fail, causing indirect injuries to humans with countless broken glass pieces flying in the air.

Heat radiation

When the asteroid collides with the Earth, it creates giant fireballs and burns buildings. High temperatures will destroy anyone standing near the place of the collision.

Humans can avoid fireballs due to the small space rock burned in the atmosphere by sheltering in the basement. But when a larger asteroid is able to collide with the city, people need to be evacuated to limit the number of deaths and injuries.

Create big craters

Asteroids colliding with the Earth often create a giant crater. Sometimes the force is so strong that the asteroid almost melts instantly. However, your ability to stand correctly in the crater area is quite small.

Eruption material (ejecta)

The process of forming craters can throw a large amount of rocks and debris into the air. The debris continued to be burned after the fireball was gone. However, both large craters and eruptive matter are considered low risk factors because humans have been killed by other asteroid effects.

If the asteroid is large enough, it will push more material into the air, blocking sunlight. If these materials exist in the atmosphere long enough, it causes plants to die and other organisms on Earth starve to death.

Tsunami

If an asteroid falls into the sea, it certainly causes a large tsunami. Tsunamis are capable of killing people living in coastal areas, away from the impact site.

Seismic shock

The collision with the asteroid will most likely create an earthquake. However, earthquake factors often do not kill as many people as other impacts.
