Hi Mr.Wood this is Owen from 2nd period science and I am awensering question 1.
I think it will kill them because they might get hypothermia. Also, it might have to make them move because it will get so cold. Yes it will change e way they get there food because it might get to cold for the animals and if animals don't live there they cant get food. Lastly, they probably wont be able to drive because there engine in there car has frozen.
Sincerely Owen Priest
