According to plate tectonics theory, Earth’s outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth’s surface over time by merging, or separating, continents.
Scotese studies how plate tectonics and a warming climate will change Earth’s appearance in the future, and he has made multiple animated maps based from his research.
