Answer :
Although the best main cause of mass extinction is suspected to be a massive asteroid impact it is also estimated that volcanic events like explosions and lava seem to have created much more deaths and increased the rate of destruction by a much further extent.
It is suspected to be in about 4 mass extinction events while asteroid impact is suspected to be in just 1.
Although there could be a number of factors amounting to mass extinction and there could be multiple differences in their occurrence but there is one big similarity between them.
