EARTH'S COLLISION WITH AN ASTEROID
An asteroid is a relatively small rocky body orbiting the
sun. Large numbers of these, ranging enormously in size, are found between the
orbits of Mars and Jupiter, though some have more eccentric orbits. I believe
that, if an asteroid hits the Earth, it could have many negative impacts on
life of this planet.
NASA states that in 1908, an asteroid estimated at 50 meters
across explodes above Tunguska, Siberia, blowing down trees across 2,000 square
kilometers and killing a thousand reindeer, but apparently no people. Because
the stony object exploded in the atmosphere, there's no crater. What would
have happened if the asteroid directly hit the Earth and at a highly populated
area? Well, it was a relatively small asteroid, but it is certain that millions
of lives would be lost.
Furthermore, we all know that it was a huge asteroid
that led to the extinction of the dinosaurs. Let’s say, what if such a
huge asteroid land on earth once again. When the dinosaurs, who were so strong
and huge could not survive it, there is no chance for us humans to survive. It could
be extinction of mankind and all other forms of life on earth. So I would say
if asteroids were to hit the Earth at about every 600 years, it could be true
danger for the lives on Earth.
