Topic:
Suppose a comet collided with the Earth; what would happen then?
Write a short essay predicting the consequences of such a collision.
I sometimes think with awe about the possible consequences for life in Earth if a comet collided with our planet. Scientists, indeed, say that a similar incidents took place many thousands years ago, & provoked the extinction of many giant animal species, including dinosaurs.
An enormous crater would form & possibly causes a volcanic eruption which would send heavy layer of particles & ash high up in the sky that can stop the sun rays from reaching the Earth, & our planet would be in the dark for many years & hence the temperatures would drop considerably.
In addition, this collision would lead to climate change. That’s to say that rainfalls & snowfalls would be irregular, heavy & long lasting. They could also lead to floods & the rise of sea level. Thus, many regions of our planets earth would be totally immersed.
Another possible consequence of this collision would be a gigantic earthquake that would destroy many inhabited areas & kill a large number of people. If it is near an ocean, a tsunami could develop & flood vast area of land, & of course causes great damage.
To conclude, we can say that facts in the past have shown that disastrous effects have been caused by the collision of a comet with earth & the same could be repeated in our times. This is why governments devoted budgets to space programmes to find ways of preventing another accident of this kind.
