This video is about 70 million years ago, when the North Pole was far away from the sun so they had been in the darknes about 6 weeks in winter, the North Pole was so cold and there wasn't a lots to eat at that time because the trees was in dormacy.....Because of that, with 4 months of darkness during the long winter, Dinosaurs had to move to another place to find more food and better condition to survive.....They had to walked 5000 miles, nearly the distance from New York to Los Angeles to escape the darkness and cold!

I choose this video because I like dinosaurs and want to understand more about their life also their habit.

New Word:
