Answer:
Earth is ever changing
Explanation:
As you can see in the passage it points out facts about volcanoes. We wouldn't have those along with mountains and trenches. Earth has been moving through out time. And will continue to move about and shift it's self. This is how you can get one species to a whole other part of land. In the past Earth's continents have been shifted and because of that this is how we find a warm, wet land plant in Antarctica.
I hope this helps!!!
