Answer 2

The correct answers are "They may cause extinction", "They may kick up dust and pollute Earth’s atmosphere" and "They may cause organisms and populations to die".

Step-by-step explanation:

The impact of a large asteroid or a comet is one of the most devastating events that had happened on Earth. The most widely known event of this kind took place approximately 66 millions of years ago causing the Cretaceous–Paleoge extinction, at which three-quarters of the plant and animal species on Earth faced they extinction. Therefore, the effects of large asteroid or comet impacts include that they may cause extinction and they may cause organisms and populations to die. Also, it is known that the most devastating effect of these impacts is that they may kick up dust and pollute Earth’s atmosphere, which results in large environmental damage that last for several years.
